I bought 56 plate from well known dealer in north glasgow January 2008
DSC warning light came on last week - the car was 4 weeks out of warranty!!
After reading posts here I was not entirely sure how much the repair would cost but unbelievably, the dealer offered the repair FREE OF CHARGE - otherwise a £1700 bill was on the way - phew!
Well done North Glasgow BMW dealer (DglPrk) - you know who you are!
Thought I was going to be ripped off but...Couldn't recommend them highly enough
