Not true. There are two verts in this thread that have had subframe issues.

I also posted this in another thread:

How does the suspension of the E46 M3 differ from that of the regular E46 3 Series?
The E46 M3 utilizes the same basic MacPherson strut/multi-link suspension design as the standard E46 3 Series. However, it has been substantially modified by BMW M GmbH with the following changes:
-Wider track both front (by 3.4-in.) and rear (by 1.8-in.)
-Unique "bat wing"-shaped forged aluminum lower control arms with M3-specific bearings, bushings and cushions
-Thicker (3mm) aluminum thrust plate
-Special wheel bearings
-More robust subframe from E46 convertible
-Separate mounting of top spring and shock anchor points
-Modified rear suspension links with steel balljoints (instead of rubber bushings)
-Larger halfshafts and wheel carriers
-Unique spring and shock rates
-Larger anti-roll bars (26mm front, 21.5mm rear)


...which concerns me because the M3 also suffered quite badly from subframe issues, and if we share the same subframes then we probably also have the same issues.

i have a 2001 M3 manual 100,000kms and my subframe mount has a crack now, only a small one.. im guessing being more than 10 years old theres no chance of getting BMW to fix it?
I have tried going through insurance.. didnt really expect it to work and they said they wont fix it as its wear damage.
Not looking forward to the bill after getting it fixed..

I would still be pushing even if its after 10 years. If they dont then basically BMW are saying the car is onyl good for 10years before it starts to rip apart..

First step is to call BMW Australia. They will either assess it themselves or send you to a dealer to have it assessed.

Hey guys being reading this thread very interesting.
It says that all E46 Bmw are effected. Is this the case for the 318i E46 sedan. 02-05?
Seems like the 6 cylinder E46 are having this problems? Any one out there had this problem on there 318i Oz version.

You sure it's that or is it that girls buy verts and they don't get driven hard

Just an update, for those interested.
BMW Australia agreed to pay half the costs as a goodwill gesture. I supplied the plates. There were two cracks in the rear axel mount. One was the right front and the other was left rear. The left rear was over 10cm but wasn't visible until the rear axel was off and the rust-proofing stripped back.

I could have forced the issue with lawyers etc as one could argue that the car unsafe due to a manufacturing fault. It just wasn't worth the effort and time off the road. As it was, I was without the car for a month!

Now it drives beautifully, with no major clunks.

I have clunks that come from the gearbox.. is that different to the "subframe clunks" ? I always get clunks from the SMG changing gears and stuff, is that normal?

My subframe clunk was on starting to move the car, especially reversing after going forward, or going forward after reversing. It was louder than the SMG clunk, which changes depending on the driving mode.

Thats good news mate, out of principle, I would have gone the whole nine yards complaining how they have fully funded the repair other cars! Either way, a result is a result and gratz and i bet your now enjoying your car!

Can we ask how much your half of the repairs were?
