A diagnostic check will show a gearbox fault relating to the transmission control module. Could be a speed sensor fault (this appears to be the most common) or a valve fault or a power supply fault to the valves
Car Clinic
We have a solution where the module is removed, repaired, gearbox oil filter and gearbox oil is renewed and all the parameters etc are reset on the gearbox. The cost of this is approx. £700 i labour and parts. Mercedes charge in the region of £1500.00 for this repair and only give the same warranty as 1 year ourselves. A massive £800 saving.
