had a problem with mark IV golf gt tdi (130bhp) last week.
car would run for ten minutes, then engine light would come on and then the car would run lumpy, as if on three cylinders.
had it checked today, fault code: 18074 - PD unit injector; cylinder 1 (N240): electrical malfunction P1666 - 35 - 10. Intermittent.
so it may be the loom thats faulty or it may be the injector itself. guy at garage said injector unit roughly £300. total prob cost £500 for fitting.
does this sound reasonable?
ive heard that if the injector is faulty it will turn off all the others. is this true?
also if anyone has one of these injector units for sale could they post here?
many thanks.
