my 2008 535Xi runs rough for the first few minutes even though I let it warm up. After a 1/4 mile, it's fine all day. Had the fuel and air filter system upfitted and it helped a little, but it still sputters a bit in the morning. ???
How many miles on the car? Any lights lit up on the dash?
63K, just had the 60K service a couple of months ago. No service prompts on dash or notifications on the Service Screen. ??
