A:you’d better go to www.foxwelltech.com to update to latest version, and remember to choose Audi  A6 USA/CAN 1998> this car model when you select.


Q:I bought a Foxwell NT500 VAG Scanner, I scanned my car whose model is VW passat 2007 2.0L and found couple of codes. I accidentally deleted all codes before I actually managed to read them. However, there were errors within immobilizer, CAN gateway and Engine, among which there is one in the engine code saying something like mass air flow sensor open or short to ground.
How to fix it?

A:It’s definitely a glow plug. I have meet the same problem on my Laguna, firing on three on a cold start, clouds of smoke, and a slower idle (the more sophisticated electronic in the passat might try to compensate for this), But it starts OK when hot. Tested them once I’d got them out, and one was shot, replaced them and all is OK.
