I have a May 2007 Audi A4 Avant 2.0tdi (170bhp) Only had it about 3 months and today I stalled at traffic lights after a motorway drive (not uncommon, seems to stall very easily at low revs?). Few hundred metres later major loss of power to the extent it would barely go up a small incline. I stopped, turned everything off and started agin, would creep up to 3000 revs whilst stood still. Sat revving for a few minutes and then everything clicked back in again and drove OK for a couple of miles. Just done another short journey 5m journey and a few miles in glow plug light started flashing and down on power again, not so dramatically but wont run over 3000 revs. Think that is limp mode? Any ideas - is this symptoms of injectors or maybe something else? Brake lights working, bit of an odd smell - plasticy? I have thought car had a little less power than I expected since I got it but nothing to base that on, just gut feeling? I can take it to an indy to have a look but if injectors I guess I should go to Audi direct for a freebie?
