I spent quite some time at the factory yesterday collecting my car after it had been there having the seemingly incurable pulling brakes fixed. Apparently mine is the only car to have suffered this particular problem. Whilst at the factory some other faults (noisy compensator for one, which were undetected by me or the dealer) were also fixed.
The Comfort Kit was only fitted after my initial test drive to check everything was ok. The brakes were fine and the car was much quieter than it had ever been, but the bump steer was quite noticeable, especially so as I hadn't driven it in a while. Having seen the Comfort Kit on some cars in production, I requested it be fitted to mine. I also tried out a Brooklands steering wheel, which is wonderful compared to the crappy standard wheel. It certainly enhanced the cockpit of my car and added further pleasure to the driving experience. Was working out to be a more expensive day than I was anticipated
I was told that the Comfort Kit was only to be fitted at the factory in order to ensure quality control. It is pretty much a bolt on job (no welding), but I guess the tracking will need to be set and of course it needs to be safe.
With regards to David G comment about a change in attitude, I fully agree. I've had a few serious faults with my car (bevel box failure on day one, cylinder head gasket leak and pulling brakes) and was ready to throw in the towel on M3W ownership, but following a frank and honest meeting and the much improved quality of my car I have changed my opinion.
Give them a chance is all I can say....and before you ask - No, I wasn't bought off
