Hi, I have a 2002 Galaxy TDI Auto. When the engine is cold there is no reverse gear, it just revs as if it is in neutral. Once driven for 10 mins and warmed up reverse is fine. I have checked the oil level in the box and it is fine. If i disconnect the gearbox management multi plug then reverse works from cold. Reconnect it and the problem is back. Please help, it is driving me absolutely nuts!!
