Hi ,
I've just bought a 110 gttdi,had to sort the headgasket all gone well.
The other day when i was on my way to work it went into limp mode and had no power.
After a couple of days it was happening all the time,so had a look and the black plastic pipe had come off the cooler.
Got it back on and went well until the nite.
Had a mate scan it and came up with 4 fault codes
17965
17563
17978
17655
Can anyone shed any light as to what these mean?moved over from mk2's so just learning about mk4's.
cheers
