I've had my car (2010 335D) in for the SES light twice in the last month. In between taking the car in, the SES light will come on and then clear on the 4th start. The last time I took the car in (about a week and a half ago), the SES light came on just a day or two later and stay on until the 4th start again. Since then, everything has been fine, but I wonder how long it will be before the light comes on again. I'm beginning to get a little pissy about the SES light coming on.
'10 BMW 335D lots of goodies
'06 F350 Lariat CC 4x4 diesel
'00 Honda S2000 (9000 RPM of wind in the hair fun)
Torque - I know the highs and lows.
