Another badly cracked E46 M3 boot floor ,subframe repair

One more E46 M3 with cracked boot floor ,this time its bit more as usual :wink: ill do separate thread about this one,as looks it will be much more work involved in this one .The owner just bought the car,brought it in for service and all these bad things was investigated straight away .So here we start ,car was fully stripped out today and all sealants cleaned off to check for all cracks .All 4 sub frame fitting points are cracked ,both front and both rear ,and even more :surprised: the pictures will do some judge .first pictures are without any clean up,later ones will show all cracks,rust signs means how long ago this happened .

Cleaned out for closer investigation

Its an absolute disgrace that this is happening should be fixed by bmw free of charge and regardless of age

major design flaw cars should not tear themselves in half :(

That looks really bad !!!!! Was it standard suspension?


It's not what you can buy . It's what you can build
[AUTOMOBILE][REGIONAL INDICATOR SYMBOL LETTERS DE]

of course it could be much worse ,and suspension set up dont make sense really

Dear god! At least its been looked after now but as Gar said BMW should be standing over these regardless.

Looks like it was repaired poorly before?

Its no more unacceptable than E36's rotting from the inside out.

If it was happening on low mileage youngs cars then it would be seen as a design problem.

This long into the cars life, BMW couldnt care one jot.

I would be interested to know if this was a worldwide issue or something confined to the crappy roads of the UK and Ireland.

Bloody hell!

Insane

It does happen on low mileage cars and the corrosion warranty is ten years on the paint from cars 2003 and up this clearly falls under corrision yet people had to fight to get it done (if they got it done) theres no excuse for it other then shabby workmanship it was poorly made id hate to see what would happen if this was just ignored

Big difference between a rusty arch and a car splitting in two john

I found the e36 to be great with regard to rust mine was 99% rust free it was an irish car though

Common in the u.s so worldwide id say

Sorry to ask this under this thread but I have a small bit of rust forming under the petrol cap where the arch meets the bumper, do I have a case as the car is an 05 or is it a lost cause ?

Il pm you to keep the thread on track

wow, I am amazed at how bad that one is. plenty of corrosion too it must have been cracked for a long time.

Is this still a weld up and reinforce job or are you going to be replacing larger sections?

90% of cracks will be covered with special plates ,other cracks will be custom fixed.in few comming days I'll update the thread .

And even very low mileage cars do crack ,think lowest one I saw was about 40k mls

Good thing the car came in to you for a check over and service, I'm sure the guy is annoyed in one way but happier in another. At least when repaired it shall be piece of mind for him.

More work done today ,all rust and under body sealant cleaned of and ready for welding works

The ends of double panels has some oem weld spots ,but they are very rare ,every few centimeters so i did extra holes in out side panel to get good weld between between them ,and some weld just at the edge .

few more with welded in all cracks and everything cowered in rust remedy ,left till tomorrow and plates to be welded on .

before and after

Words fail me here! Did the new owner not have it inspected pre purchase? Bit of a kick in the b@lls - bitter sweet, as it'll be perfect once it leaves the doors of Valdas :D

A friend of mine works in ace autobody (bmw approved) and said he's done a few jobs like this for bmw ireland. He has only ever done normal e46 coupes. Never an m3. I assume they would be the same tho...

As always great work Valdas.
Question and it might sound stupid,

What would happen to the car if this is not repaired and still been driven like a M3 was made to be driven?
Any real horror story yet?

it could be deadly bad :wink: http://www.youtube.com/watch?feature=player_detailpage&v=scKLdW3x6oY or lost its back suspension on the road ha ha

Wow, great video. I'm amazed that was let get so bad.

Unbelievable fucking ducktape :( scary stuff

plates are on

some primer ,some silicone , under body sealant and shes ready

One example of some crack repair from inside the booth ,floor should be cut out to open the frame of one of fitting points .
[hr]
Thanks for looking :wink:

What no ducktape :D

Excellent work as always :cool:

Cracking work as always V.

Would it worth welding plates on as a precaution to prevent cracking happening?
