since you're not the first owner of the car, better ask if they did something on the front lamps or if they have replaced the front SAM and didn't do the coding. check closely too, maybe the small bulb is really busted...but it is unlikely for both of them to get faulty together at the same time.

about ESP/ABS, have the fault code extracted. it can be just a minor problem such as wheel speed sensor or low voltage on control unit.

in sport, it always start to first gear while you don't have it in comfort mode. it also got effect in ADS on suspension. does the downshift makes any difference if you switch between C and S?
