Either low voltage to the pump or a speed signal is missing, do the lights come on when the engine is running and before you have moved the car

First thing is to make sure that you have 12 volts going to the pump, you could have an OVP relay on your car and these fail

by pump i presume you mean abs pump?

Yes I do mean that, your car is a later one and should have the OVP relay fitted

hi, i have a c250td auto which i believe had the same problem, the car was stuck in "limp home mode" and only used 2nd and reverse gears as a result of a faulty ABS sensor in the diff , the part was 70 quid and an indie MB garage fitted it at a total cost of £180.
