Hello, Just bought a 11/2006 A6 Allroad 3.0 tdi, great car but yellow engine light on all the time. Vag com gives codes 05650, 12597, and 04120, my kit is too old for these codes and cannot say what they mean, could any members advise as to what they mean and what action is needed to sort them. I have read that the main reason these cars are taken to the dealers is because this light is on and it may only need a sensor cleaning. The car runs fine with good fuel consumption, 10,000 miles until next scheduled service. Don't want to waste money taking the car to the garage for nothing. Regards, Michael
