Well i just bought my E90 about 3 months now and sent it in for the first service after owning it at the dealership.....then i decided after the long holidays to take it someone private to have the car checked up and found Air Filters have not been changed, rear brake pads were worn to a point i was lucky if i got another 1000km. So i told the mechanic to do the full service including my aircon filters. And it cost me R3400 which is not bad. Now I am waiting for a day to go them and give them a piece of mind and throw all serviced parts at them.
