Audi A4 2.0tdi loss of power problem
My mate had an Audi A4 2.0tdi 2006 model, he's been having this loss of power problem, it first started only being a holding back issue over 3000 revs, but has got a lot worse recently right through the rev range, it actually conked out on the way to work the other day n would'nt start for 5 mins till it had cooled off a bit, today it's running fine as it used to full power again.
Do you think maybe it had a blockage in the fuel filter of injectors thats now cleared cos he's been using tesco's cheap diesel???
Thanks in advance jammy.................
