sorry about the delay in updating.... its just i haven't had much progress to report back
, and i've broken a few vital parts.
ill hav a few pics up in a mo.
The sensor that you have removed to do the pump timing is called in volkswagen talk "commencment of injection valve" this valve talks to the automatic glow plug period control unit, which controls the injection timing - mainly arounf idle and part load.
I am trying to sort this out in my T25 which has an AAZ in but no control unit as yet!
Hope it helps
John
Hi
Does that mean that the sensor could be the main cuase of the problem? have you tried replacing your yet?
I am sorry I haven't got a clue! I just know what the sensor is!
If it is at fault a code reader will tell you as the ecu for the pump (yes it does have one) will tell you. Might be a dealer thing for you though.
