Impressed with your spirt and humour with all this Javier, I don't think I would be quite so good with it. You don't HAVE to have your car trailered home for the full M3W ownership experience. I have never failed to get home with my M3W yet in 7 years of ownership and 26,000 miles, although it has been close on one or two occasions. That may be tempting fate.....but my M3W is a far better car now than when it was new, mainly down to the pooled experience of this forum.

I really hope I am wrong but from the limited description, I still think it sounds like the Centa rollers have broken up (6). They can have some drive with very little roller left and some have been known to break up at very low mileages. At least it is all under warranty, no need for your hands to get dirty or get your wallet out, just the loss of your nice new M3W for a time, not good.
