Thanks for these replies, am not sure which mk but is now about 5-6 years old, no fancy extras, 1.9 tdi, greater of the 2 hp's, 115 i think, manual gear box. I will do some inquiring about changing the glowplug and try to change it myself :lol: You were correct, there were quite a few posts on this, i will try to digest as much as possible first. I did read in one of the posts that the unit can be dissabled? at least until it's repaired.
