I´ve to correct myself... electrical emergency mode is without any lights on. So everything seems to be normal but the gearbox only uses the third.
I´m pretty sure that you´ll have a problem with the throttle sensor (G69)
1. Cleaning contacts (Cantact spray)
if it doesn´t work ..
2. Read ot the fault recorder by using VCDS or the "old-school" -way
possible codes are:
00518 - G69 faulty
00529 - REV information is missing
00538 - reference voltage
00545 - Signaling ECU <-> geabox ECU broken
00549 - consumption signal
