Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** transmission had gone into limp home mode. Turning the car off and back on will sometimes reset the transmission and it will shift normally. If that doesn't work you will need to get the car connected to the Mercedes Star Diagnosis tester to check for fault codes in the transmission and traction control systems. The problem is typically caused by a faulty speed sensor. There are speed sensors in the transmission and at the 4 wheels.
More than likely the problem will be with the transmission speed sensors.
