Just back from dealers and had four new 108s fitted as good will gesture by bmw uk. I wrote a nice letter of complaint and was lucky they agreed to replace them, all I had to pay was £50 for fitting. I also had electric window regulator fitted under extended warranty. So good day at the dealers. Only problem is my tyres, falkens, need replacing. 3mm and 4mm what is the legal depth now??? So my advice is to write to bmw with your problem you never know you might get lucky as I did.
