Q & A
Why did the original buyer sell the BMW M5 to the current owner?
-The original buyer sold the BMW M5 because they encountered a problem that was stopping them from fixing the car, which made the repair more difficult than expected.
What attracted the current owner to purchase this specific BMW M5?
-The current owner found the BMW M5 listed on eBay for £33,500, which was significantly cheaper than the usual price of around £50,000 for similar models, making it an attractive deal despite its crash damage.
What were the initial damages noticed in the auction photos of the BMW M5?
-The auction photos showed that the car had a front-end collision, missing the bonnet, bumper, headlights, and possibly a few coolers. Additionally, the driver's side wing looked repairable, but the passenger side needed a new inner wing and all the airbags were deployed.
What specific issue did the BMW M5 have that caused concern for the current owner?
-The car's oil cooler, positioned at the bottom front, was damaged, causing the oil to leak out. The owner was concerned about the engine potentially having run without oil, which could cause serious damage.
What makes the BMW M5 Competition model special?
-The BMW M5 Competition comes with a 4.4-liter twin-turbo V8 engine producing over 600 BHP, has four-wheel drive with an option to switch to rear-wheel drive, and is a high-performance sports sedan.
What was one of the main obstacles in moving the car into the garage?
-The car had no power, making it difficult to release the electronic handbrake and put the car into neutral. The owner had to manually work around these issues, including climbing through the back seats to access the battery.
What unexpected damage was discovered after purchasing the car?
-The car had significant structural damage, including a large hole and dent in the strut tower where the suspension sits. This damage suggested that the engine might need to be removed to complete the repairs.
Why is the strut tower damage particularly problematic for repair?
-The strut tower is made from special cast aluminum, which needs to be bonded to the car’s frame. It’s a critical structural component, and repairing or replacing it may require removing the engine due to limited access.
How did the owner plan to assess whether the engine was functional?
-The owner planned to bypass the damaged oil cooler by bridging the oil lines and refilling the engine with oil to see if the engine would start. The goal was to get the engine running before investing in further repairs.
What challenges did the owner face while trying to start the car?
-The owner faced multiple issues while trying to start the car, including power problems, the potential of a blown pyro fuse (a safety fuse that blows during airbag deployment), and the car not responding despite attempts to bridge connections.
Outlines
🚗 Taking a Risk on a BMW M5
The speaker didn't purchase the BMW M5 from an auction directly, but from someone who attempted to fix it and failed. The car was crash-damaged, and the previous owner couldn’t address the issues. The speaker explains the risk of buying crash-damaged cars, especially from those who have already tried and failed to fix them. Despite the damage, the speaker thought the car looked manageable for repair, especially since many parts behind the front-end damage seemed in decent shape. However, the speaker quickly realizes that this is going to be a far more complicated project than expected.
🛠 Power Struggles and Broken Components
The speaker details the challenges of getting the car powered up and into neutral to move it inside. After a few failed attempts with jumper packs and struggling to open the boot, the speaker finally gets power to the car. However, the digital display shows multiple errors, and there’s a significant challenge in disengaging the electronic handbrake. Even after accessing the gearbox and using a zip tie to put the car into neutral, the handbrake refuses to come off, further complicating the process.
🔧 Structural Damage and Engine Woes
The speaker reveals that the BMW M5 was purchased for £32,500 as a Category S (structural damage) vehicle, and similar models in good condition are priced at over £60,000. The critical issue is severe damage to the strut tower, which suggests the engine may need to be removed for repairs. Although the frame seems straight, the strut tower's damage might make this a very costly fix. The speaker remains hopeful that if the engine needs to come out, any existing damage could be addressed during the process.
🚦 Troubleshooting: Bridging the Oil Line
To get the engine started, the speaker bypasses the damaged oil cooler by bridging the oil lines. After draining what little oil remained and inspecting the turbos for debris, the speaker moves forward with attempting to start the car. However, the car still won’t start, leading the speaker to suspect a blown pyro fuse—a safety device that could have triggered when the airbags deployed. The next steps involve locating and investigating the fuse to diagnose the issue further.
🔋 Success and Unresolved Engine Issues
After bypassing the pyro fuse, the speaker finally gets the car to crank and briefly run, confirming that the engine isn't seized. Despite this minor success, the car doesn’t run consistently, and the root cause of the problem remains unresolved. The speaker signs off by promoting BMW-related merchandise and expressing excitement about tackling the next steps in the repair process, leaving viewers eager for updates on the project.

Highlights
The buyer purchased a crash-damaged BMW M5 Competition from someone who couldn't fix it after buying it from an auction.
The BMW M5 was listed for £33,500 on eBay, much lower than the usual price of £50,000, due to the damage.
The car has a 4.4-liter twin-turbo V8 engine with over 600 BHP, a key attraction despite the significant damage.
The car sustained a front-end knock, with damage to the bonnet, bumper, headlights, coolers, and more.
Airbags on both sides, including the dashboard and curtain airbags, were deployed, contributing to repair challenges.
A major issue is the oil cooler located at the front of the engine, which was destroyed in the crash, causing oil to leak out.
The car was labeled as a non-runner, with significant concerns about the engine running without oil and potential internal damage.
A structural damage issue was found with a hole and dent in the strut tower, which might require engine removal to repair.
The car has a category S designation, indicating structural damage, and was damaged over a year ago, yet remained unfixed.
Attempts to start the car failed initially, as the electronic handbrake wouldn't release without power, complicating the repair process.
After bypassing the oil cooler and refilling the oil, the engine still wouldn't start, possibly due to a blown pyro fuse.
A pyro fuse was found, and the team attempted a risky bypass with zip ties and jumper packs to try and start the car.
Finally, after numerous trials, the engine cranked but did not start, raising concerns about the extent of the engine damage.
The buyer expressed relief that the engine wasn't seized but remains uncertain about the full extent of the mechanical issues.
The video concluded with the anticipation of further costly repairs and possible engine damage, leaving the project's future uncertain.
Transcripts
I didn't buy this BMW M5 competition
from auction somebody else did but then
they sold it to me after they realized
one problem which was stopping them from
fixing it
buying a crash damage car is risky as it
is but buying it off someone who
couldn't fix it adds a lot more to the
risk now you're probably like me find a
car that you won or dream of owning
search on eBay or AutoTrader and then
put lowest price first or does that just
make me a cheapskate now I actually
found this BMW M5 listed on eBay for 33
500 pound and usually these cars go for
around 50 000 pounds if not more and
it's easy to see why the BMW M5 comp
comes with a 4.4 twin turbo V8 which has
over 600 BHP now actually managed to get
it cheaper than that but we'll get on to
what I paid for it later in the video
because I'm kind of thinking now it
might not have been worth it but on
First Impressions okay some of you might
think I'm mad but even on the list and I
didn't think this car looked that bad
it's had a front end knock but
everything really from the wing
backwards looks Sim half decent shape
for someone like me who doesn't really
have any type of skill is more of a
driveway mechanic that self-teaches
himself I thought this could be an easy
repair
but oh is this gonna be far from an easy
repair the car I bought this from was
kind of like myself he was repairing
cars on his driveway so looking at the
auction photos of this car you could see
well it needs a front end there's no
Bonnet there's no bumper headlights and
maybe a few coolers as well the driver's
side Wing looks repairable the passenger
side Wing not so much it would need a
new inner Wing which just requires a bit
of welding and all of the airbags are
blown including the dashboard and both
of the curtain airbags so really looking
at that damage we could probably repair
this on a driveway with no real special
tools required and have a decent M5 for
a lot less than the normal price but as
always when dealing with cars as I'm
sure you'll know it's not as easy as
that and in this specific case there's
two reasons why it's not as easy as that
and the first reason Hannah's going to
explain and why is that the engine
doesn't yeah this is a non-runner
because BMW decided to put their oil
coolers at the very bottom at the front
of the engine so if they're ever in any
accident they get absolutely smashed a
bit so this is dropped all its oil out
and you don't need to be a genius to
know what happens to an engine when it
has no oil in it we've just got to hope
it wasn't ran without it the oil cooler
looks
like it's just pulled out of the there's
the top of the oil cooler and there's
the pipe it looks like it's kind of like
I think it's definitely knackered I mean
that is yeah that's definitely
but it's like pulled out I think you've
got like a oil feed in here
and then the oil will turn in there
there's the auxiliary belt
oh dear what's that
[Music]
oh is that a pulley there oh
ah
no it's like a water pump oh my God
there's so much broken here oh even
that's broken
um charge cooler oh dear do we get
Hannah's approval on the M5 I mean don't
come for me but I don't like BMWs
this is a 4.4 liter V8 twin turbo it can
be like a thousand horsepower and look
at the interior four-wheel drive as well
and you can make it into rear wheel
drive it doesn't have a heated steering
wheel it doesn't have any Steel
[Music]
like me I never used to like BMW and
then you're in your drive on then you
like it now the engine has to come out
the M5 anyway to do a certain repair on
this but before I explain why we've got
to try and get the car into neutral so
we can push it inside the unit
we got power
[Music]
got no power
weirdly it seems like my jumper pack
didn't work so I went and fetched a
bigger one the battery's actually in the
boot so we're having to use the
terminals which are underneath the
Bonnet we've got 7.5 volts so flies
absolutely nothing but still nothing so
the only other option was to put the
jumper pack directly to the battery in
the boot but we can't open the boot
because you need electric to open the
boot so we're having to climb through
the back seats to gain access to it
unless you guys know of an emergency
release that I could have pulled to open
the boot but I didn't know so we're
crawling in the back red
foreign
we have a problem he got a reading no
nothing no
so there's three lines there's no
reading at all
what
oh
does that work yes we've got power we've
got power on we've got power on it must
just be really dead yeah our digital
display
Okay so we've got digital display oh
nearly a full tank of fuel come on so
loads of faults can you put this in
neutral
I don't want to start it that's the
thing do you know if I just pressed
press to start engine press brake pedal
I don't want to start the engine that's
the thing there's no oil in it I don't
think
you can get it in neutral
I can't even take the handbrake off
I think what we've got to do is get
underneath it there might be a notch in
the gearbox I'm pretty sure there's
gonna be a notch in the gearbox we can
work it into neutral but that doesn't
solve the handbrake not coming off the
back we're gonna need power to get the
handbrake off the bat oh we can open the
boot we can open the boot now
no we can't well it's not looking good
so far
so I've got the Jack out to see if we
can find something on the bottom of the
gearbox I've watched a video apparently
all you need is a zip tie to do this
let's see if that is true
uh there's the Box
is the gearbox
okay so is this
that lever apparently you pull it down
and then zip tie it
to the prop shaft and that will put it
in neutral I'm gonna put you guys there
let's see if I can do this
this turned out to be way more difficult
than it looks the prop shaft was in the
way of this lever and I had to somehow
bend the Zips around to hook it over the
lever which puts it into neutral I'm
smooth
I'm just gonna get it after a bit of
fiddling around I eventually got the zip
tie through the little hole on the lever
and it eventually could start to pull it
tight in hopes that that would pull it
in neutral
aha
okay everything if we pull that down
[Music]
oh
round two bigger zip tie I'm double zip
tied
holding that lever down
if that don't do it
I don't know what will
front wheel moves
bat wheel no
at least get a parking brake
see ya
[Music]
see if the handbrake will come off
okay the handbrake doesn't like coming
off
coming to think of it
this is the only BMW that I remember
having an electronic handbrake all of
them have manual handbrakes they thought
it was cool to have a manual handbrake
but all of a sudden they decided it's
not cool to have one
and which means you can't move it
when it's crashed so plan of action was
to plug the auto diagnostic into the car
and then put the handbrake into a
service mode which again didn't seem to
work
[Music]
turn off
why does it not turn off it says in
addition press the brake pedal I'm
pressing the brake
[Music]
finally we got the handbrake off and the
car was in neutral and we can now begin
to get the BMW M5 into the unit which is
getting me so excited to get started on
it now before I bought this car I did a
car vertical check on it and on the
check brought up something quite
worrying check this out so I put the
registration in and then I got my check
and straight away I can see there's been
no mileage fraud it's not been recorded
as stolen but there is an amber light
for an accident of course and there's no
outstanding Finance on it as I scroll
through the report I can see every time
an ownership's been changed and every
time a registration plate has been
changed on the car but that's not what
was Rory and me I can see the M5 got
written off as a category s but this was
in February 2021 last year so the car's
been damaged way over a year and nobody
has decided to fix it
[Music]
but just to mention the cool thing about
Carl vertical is that it works in over
20 different countries and it can
uncover a lot of hidden history like on
this C63 this car was crash damage and
cover vertical actually have the photos
from when the car was auctioned off at
the car crash auction website you won't
believe the amount of people which are
driving around in a car that they don't
know the full history of which is why I
urge you after this video ends to check
your car out or a car that you're
potentially about to buy by using car
vertical with the link in the
description box below and use code map
because that will save you a bit of cash
as well so the BMW M5 as is cost me 32
500 pounds it's a category s which means
structural damage it's a 2019 and
according to the seller this has only
got 10 000 miles on it M5 competition
with the same year the same spec but not
crashed you're looking at about 63 to 6
65 000 pounds so in my opinion I think
that leaves you with around ten thousand
pounds give or take to make this scene
worth it and get it back on the road and
for it to be a cheap BMW M5
that was until the previous owner found
this damage
[Music]
this is the damage which is gonna cause
hell there is a huge hole and big dent
in the strut Tower which is where the
suspension sits and for that reason we
think the engine has to come out
with the car being category s which
means structural damage which it does
have quite clearly I don't actually
think any of the frame is bent I think
it is all straight but we will have to
get it checked out good way to see
whether anything is obviously moved for
this structure is to check these struck
braces right here and well nothing in
his mood you can't see that the strut
Towers move back left right or Twisted
in any way the bolts look like they're
in the same place and on this side
yeah it's all the same on that side with
this chassis legs this part looks okay
that part looks like it's gone but we
can get that all measured but I think
this hole was caused by something
piercing straight through the Bonnet
there I don't think it's any sort of
stress on the suspension that's caused
it looks like something has literally
hit the Bonnet gone straight through it
and Pierce that huge hole and the worst
part about it I believe that strut Tower
is made out of a special cast aluminum
which needs to be bonded to the frame of
the car
this is a huge piece and a vital part of
the engine and it actually goes all the
way down there and further down the back
as well and I don't think we will try
but I don't think we will actually be
able to get to it and bond it and take
it off and put a new one on without
removing the whole engine because I
don't think we've got enough room to
play with here but if it's only that
part to replace the front end and the
airbags this could be a cheap repair
but that's if the engine's okay the only
positive to this is that if the engine's
got to come out any way to do the repair
then if there is any damage to the
engine then we can fix it whilst it's
out but that could get very expensive so
I think and I hope I'm right in saying
this I want to get this engine running
first before we start stripping it apart
to see if it actually works and the way
I'm going to do that is I want to bridge
the oil line from here
so here so that we're not going through
the oil cooler which is obviously broken
and then it should hold oil in the
engine and fingers crossed it ticks
overnighters
here we go
whilst I had the M5 up in the air I had
a quick inspection to see if I could see
any more damage but always looking good
so now I'm removing the hose out of one
end of the oil cooler and then I can
pull the old oil cooler away from the
car then I've got this super long
silicone hose which I'm going to use to
connect one oil cooler hose to the other
one doing the complete bypass of the
front oil cooler obviously this is not a
long term fix but it should work to get
the car started with the BMW being a
newer car it doesn't have a dipstick so
there's no way of telling how much oil
is actually in the engine so what I'm
going to do is drop what's left of the
oil into my oil tub and then I'm going
to refill it with the amount of oil that
it needs
well there's supposed to be 10 and a
half liters in this engine and only
well not even about three and a half
came out so I'm gonna put this back in
top it over some old oil or something
like that we just want to see if it's
running of course I'm going to replace
the oil at some point but yeah it's not
looking good at the minute
the only good point you could take from
this is that I didn't notice any metal
shards or anything unusual in the oil
that actually came out before I try and
start it as well I'm going to remove
this induction pipe just to check
there's no plastic or any debris that's
worked its way down and into the turbos
because if I start it and there is then
we could cause some serious damage there
[Music]
foreign
looking good and there's no play in the
turbo either
let's hope it stays that way right
now I don't know
I don't know whether this has a pyro
fuse in it which is the fuse which blows
off
um when the airbags go I've had a look
in the back here and it looks like
something is missing from this bit here
but other than that I can't see that it
actually has one so I think it's just
going to be trial and error
[Laughter]
yeah if it starts sounding crazy I'll
just straight turn it off that's a good
idea
just double check the oil now because if
some if it's awesome
services
how do I put the phone down I don't know
are you in any trouble yes I've got
other front ends hanging off the off the
car okay here we go just gonna send it
did that even crank
it don't want to go
oh oh I know I know I know I've still
got it in neutral underneath
[Music]
okay is that
yep so it should be in part I think this
is it now it should be in Park oh this
is the disorder and this is what risk is
about
I'm gonna I'm gonna do it
I'm gonna do it
[Music]
oh
still no luck the only thing I could
think of is that if this car has a power
of Technics fuse on which had blown
right is that a pyro fuse but to be
honest I couldn't really see anything
obvious
if this don't do it then power ain't the
issue so we just resorted in using a
bigger jumper pack in hopes that it just
didn't have enough power to start
come on
it doesn't want to do it it's just
nothing I've got my foot as hard as I
can on the brakes I'm pressing the start
stop button
[Music]
literally nothing is happening so still
no luck so there must be a pyro for you
stopping this pyro fuse has been found
it's definitely
well on the looks of it you've got your
two cables there that looks very air
buggy there
so ah yes there it is down the bottom so
what is that bridge in and the only way
to find out that was to start stripping
it apart
then it could work out exactly what was
going on down there
right
here's the Pyro fuse just there and from
what I've worked out I think these two
uh have got something to do with the
engine start so ones could go to the
starter motor
um
I don't know what the other one does
I've never seen two of them go to the
par reviews but I would assume if that
fuse is broken underneath then the power
which is going directly to here so the
power
the power goes on the battery directly
onto this line here and this is all your
body electronics and everything there
and this is what starts it so
this is what starts it so I think if I
bridge the gap between that to there we
should get a start well at least an
attempt if this is not the sketchiest
thing you've ever seen then you've seen
some sketchy stuff because we are
connected there to there to there
hopefully
saying that to reckon it's gonna do it
is only one way to find out there is
only one way to find out and that means
to start it is it okay
there we go ignition
ignition
ignition
[Music]
it cranks then didn't it
I lost power
okay I'm a bit nervous now because that
did not sound good
ignition
come on Beamer
oh
it's clear quit
what's happened
[Music]
yeah it went from being like this again
do it again well you do you know you
don't think it's going to blow off that
part though
okay ready
no
no
it's done it definitely ran at least we
know it's not seized up I don't know why
it won't run consistently but if you're
a beamer boy like myself you can grab
the BMW M sport hoodies with the link in
the description box below thanks so much
for watching this video if you've
enjoyed it hit that subscribe button hit
that thumbs up button and I'll see you
in the next video peace out
[Music]
yeah it's uh part of the airport
oh dear
oh what a ball like
[Music]
[Applause]
a drug
