Hi All, long time since ive been on here but im back! Now with a troublesome Golf!

Anyway, have this 2002 GT TDI, well maintained but slightly high miles @ 136k.

Seems to run fine 99% of the time. The problem i have is that sometimes the turbo just stops, well it fells like that. 800 miles in the past week and its happened 5 or so times, 4 of those times when i was going up hill. Now if i turn the engine on and off all is well again.

I scanned it and have the following errors;

17664 - P1256 Engine Coolant Temperature (ECT) Sensor (G62)
Open circuit/short circuit to B+, 35-10, intermittent

17964 - P1556 Charge press. ctrl.
Value below lower control limit, 35-10, intermittent

16485 - P0101 Mass or Volume Air Flow Circ. (G70)
Range/Performance, 35-10, intermittent


Any hints of where to start with this? I have browsed the net and it would seem wise to get a new MAF for starters?

Cheers!
