Wondering if anyone can shed some light on this for me, got a 04 a4 2.5 163 sport from a guy at work, he's been running it on red diesel for years, got a bad batch started running crap, I got it this week, put it into my mates garage he found water in the fuel filter, took the pump of, full of crap, cleaned etc, drained the fuel tank.. New fuel filter in..
It struggles to start in the morning, loads of white smoke, its pretty much impossible to move the car till maybe 2 mins after start up and the smoke has cleared. Then it's runs fine until u hit 3000 rpm. Really struggles to go past this and the traction control light comes on at the same time.
Does anyone know what could be wrong? Ive seen a few similar related problems on the net that suggest maybe the pump timming could be out????
Getting fault codes 17583 and 00550
Any help would be much appreciated
