I have just read this thread, cant believe I never seen it before!
Anyway my 150 Euro 6 Manual (which has just passed 10k) keeps throwing up the engine management light, both the engine shaped one and the pigs tail one, however they do not always come on at the same time. When the light comes on its usually under acceleration and the van then shudders, sometimes the light goes off as soon as you restart the engine and its fine, next time it can stay on for hours. There is also sometimes a lack of power and it keeps shuddering, like kangaroo petrol almost! But other times there is no loss of power at all. This has been happening since around March, there doesnt seem to be any pattern as to when it comes on either.
I thought it may have something to do with the DTUK chip that I have hence why I havent been in contact with VW yet, however I am thinking it may be a VW fault after reading this thread.
