Brake light switch problem may cause the ESP / BAS lights to illuminate.
Common symptoms of a bad
Mercedes brake light switch.
TEST: To test your new brake light switch: Turn you car off to reset the ABS light. apply the parking brake. and start the car in neutral or park without using the brake. if the problem is the brake light switch... the light will only come on when you press the brake pedal.
If you replaced the brake light switch and the light is still on you should check a few other things such as:
NOTE: ** You may need a MBZ scan tool to reset the error code which was stored in the ECU because of the bad brake light switch.

well.. the output speed sensor is the output side of your transmission speed sensor... these are horrible on merc's... easily replaced... but a pain to get the correct one.. and this sensor could cause almost all the problems you list alone... but with such low miles it may be a warranty item? as it is on your transmission...

mercedes did nothing wrong your transmission is probably blown up. no way they could put in the wrong parts they wouldn't fit. how many miles are on your trans now? did you ever do a transmission service on the transmission that mercedes says is lifetime fluid? dont do back to the dealer find an independant shop that specializes in mercedes, like the one i work for. the dealer doesnt care about its clients. Us independants honestly do care
