Also some of the people who work at BMW main dealers I would'nt let work on my kids push bike never mind a csl.
OP take it to Redish or there's others who can fix it properly (there's more options than just plates)

If I remember correctly NZ_M3 a few years back posted a good write up why plates do not work. The foam injection was also discussed.

Personally with high expectations regarding service histories etc on the Csl, buyers would expect repairs to be done buy BMW, any other repairs could possibly knock valves, But nothing wrong with useing polyfilla

The BMW repair IS better than the welding of plates (IF the injection of the resin isn't carried out as well)....

If you look at any repair that has been done with just plates and you understood why it cracked in the first place, you would also understand why just welding plates on is even more of a disaster than the original problem....

BMW are good for somethings. If csl wasn't what it is ,and just a £7k e46 m3 I'd have no problems with tin foil and polyfilla repair, as I do 99 percent of my own maintenance anyway

How come? As said earlier, BMW just replaces the cracked subframe with a new one while the issue remains. Its a fact that new cracks developed after BMW replaced the subframe. On the other hand i have not seen one subframe fail after its been reinforced with good plates and got uprated bushings.

I would like to hear your opinion on what you think is the issue, why the subframe cracks.

For a bit of fun let's put it to a vote. BMW new floor pan. Verses welding plates. My vote goes to BMW fix. But I'm not against welding plates for cheaper fix.

My Point is, a new floor pan from BMW is no fix at all.
