Worried with those subframe stories

[Mike RT4]

This may help you locate them - here are photos of the cracks on my car that Gareth took for the warranty work to be done.

FYI mine was checked as follows:
November 2012:
No cracks

June 2013:
No cracks

September 2013:

Yes, I agree with you JBird.

I'm quite upset with BMW at the moment...

On top of their recent ugly designs and turbo-engine philosopy, they handled this problem quite badly.

I'm sometines leaning to sell my beloved CSL I confess...

[Alx007]

Wow, that's impressive!

Thank you for the pictures Mike!

BMW are having a fookin laugh saying that this doesnt happen and denying it in Germany ..then coming up with Technical Bulletins and stupid crazy foam fixes ... I may write a letter to them and say Im going to drive around in it until the floor gives way and kills me !:hahaha: ... then I will sue them :thumbs:

There speaks a man on a mission :hahaha:

They can't deny that the problem exists as they issued a worldwide memo to all Dealerships in 2003, advising them of what would be required to undertake their preferred fix eg. Plates and 2 pack Poly?Filler!

Did BMW suggest plates in the memo? My understanding is that the BMW fix is to replace the floor, and the option of the epoxy resin injection on one side

I've heard that the new floor they put in is the same as the original E46 M3 convertible one which is stronger. No idea if this is true though...

There is only one part number for M3 E46s.

So is it possible for a 'replacement' floor to again.... crack?

[Monkey]

Danny,
Do you know if the replacement floor sections have been redesigned with the dowels, or are they the exact same?

Looking at the photos of the new section that Mark posted up, I am unsure of the differences?

The new boot floors are exactly the same. Gorilla, we have seen 2 replacement boot floors fail again within a 3 year period of the repair.

Just go full weld in cage. Job done.

With the foam fill?

when i bought my csl I also concerned about the subframe stories.
My csl with 45k miles had no cracks, but let them welt preventive the reinforcement kit on the car.
when i read the horror stories on the web every e46 M3/M3 CSL will get it at some time of its life.
(I paid 1000 euro for the job with new subframe bushes, PSG Geel M specialist in belgium:notworthy
