I have the bolt in “A” frame, I’d always associated continued cracking problems with the original simple bolt in cross piece not the “A” frame?
The bolt in "A" frame does not eliminate the crack problems but may reduce them. There is more to the post 2014 chassis than just a welded in "A" frame cross brace I suspect. Although I cannot say with 100% certainty, some of the tube gauges are thicker and possibly of a different specification. As far as we are aware, there have been no cases of the detailed cracks on post 2014 specification chassis and the MMC "recall" was not applicable to post 2014 chassis cars. Sadly DVSA didn't make MMC issue a chassis crack recall. The faulty early brake pedal design remains the only official recall for the M3W. The chassis cracks were only mentioned in the information at the top of this forum section by MMC. Possibly DVSA and MMC considered the cracking of the front suspension mounts to be a non catastrophic type failure? Let's hope they are right.
If you have a pre 2014 specification chassis car, I suggest you familiarise yourself with what and where to check on the chassis and check it periodically. A scheduled dealer service is no guarantee that the chassis will not be cracked. As mentioned, the information is freely available on the MTWC website.
A bit of thread drift there Phil, sorry. I hope you find a suitable M3W.
