Following a few problems starting in cold weather (engine hesitates then judders before bursting into life) I checked the glow plugs and found one to be dead.
I checked the part nos and only one is listed for my AMF engine code, 2001 TDi. Audi also checked the p/n and confirmed this to be N 105 792 01. When comparing it with the old glow plug, I found the new one to be approx 5mm longer. Luckily I have a spare cyl head and was able to check the protrusion of both plugs and the new one definitely did not look right. This is just my opinion but I wont be fitting the new glow plug until I've got some sensible answers from Audi. The Bosch parts book also specifies the longer glow plug but I guess they only get their data from Audi and would duplicate the error - if there is one?
For info, the glow plugs are quite easy to remove with a 10mm 1/4" drive deep socket and are stamped with the Bosch part nos. For anyone needing to change glow plugs, my advice would be to remove one, check the number and order from a Bosch dealer.
Sorry the pics of the glow plug protrusions are not too clear
Cheers Spike
