Subframe Issues

422 posts in this topic

Its fairly common on the early E46's. So i thought i'd make a sticky, so newbies can find it easier.

This is to do with the rear subframe cracking/splitting on the E46's.

BMW know of this problem, they even have documentation for it, but still sometimes deny its a manufacturing problem and try to get owners to cough up the money.

There are "fix kits" which are basically sheets that get welded to the subframe, but ideally you want it all replaced.

I've personally had this problem and BMW fixed it for free 100%. Apparently at a cost to them of £2500.

Here is the BMW PDF

Please post if you have had the problem, letting us know the details, if BMW paid etc..

Member Phantom Mark has written a DIY if you choose to fix this issue yourself: http://www.e46zone.com/forum/index.php?showtopic=14652

Yours should be alright as I believe that this only effected early 323's and 328's iirc.

I am honestly speechless about this........not actually looking forward to looking at mine, I think I would have felt a problem like this tho when driving, or clunks from rear end etc.

Where exactly should we be looking for this ?

Does it just affect some older cars?

if you are stood underneath the car as if you've walked under it from the rear, facing the front and the nearside wheel is on your left,

then you should look in the area of the coil spring and slightly to the right,

there is a mounting bracket with a big bolt through it, and if the area round this

is cracked, you have a problem. (well that was my case anyway)

Ouch :rolleyes:

I had mine checked out last week. The mechanic said yes it was a problem, especially with the older E46s, but that it was actually quite a rare problem. Luckily mine was fine. I was worried because I sometimes get a deep THUD when changing from 1st to 2nd and thought that might be it.

Take it to BMW complaining of a loose back end etc. They should tell you its the subframe and offer to fix 100%. thats what happened to me.

If they blame something else, drop a hint your local mechanic said its the sub frame.Then argue it for free!

Good luck
