Starting to get a little miffed with BMW, could be coincidence but I'm not at all convinced. I've now had the 1 series for a year and a half, it's been in to the dealers three times now and twice, the next day, the drivetrain warning light has popped up. Last time the dealer booked it in asap (the following day), investigated, turned out someone hadn't put something or another back on correctly. This time, they won't check it out until the 7th December and are stating it's nothing to do with the service work.
Part of the reason I bought the car was due to the warranty and that I could chuck it at BMW should anything happen and they would sort it (to a point) but having to constantly take it back due to them screwing up is becoming a joke.
