G55 wont upshift, fault codes included
Hi, I got a 2007 G55 AMG.
Suddenly the car will not up-shift and stays in a low gear giving 80km/h with at 7000rpm.
A friend helped me get some fault codes but haven't got a clue as where to look first for this problem. Hoping for any input.
Fault codes transfer case:
P2220 The supply voltage of the control unit is too low (undervoltage)
P2122 The CAN signal form control module N15/3 (ETC [EGS] control unite) is faulty.
P2111 CAN communication with the engine system is faulty. On vehicles with diesel engines: The fault can be ignored.
P2120 The CAN signal from traction system is faulty
P2260 Component M46/2 (Transfer case position motor) or (and) the transfer case is jamming mechanically.
