Smoking on startup and acceleration.

Post by explorer121 »

Hi,
wonder if anyone can help. My 2003 B5 1.9Tdi 130 smokes on start-up and when I accelerate hard there is a cloud of smoke left behind. Yet on revving it to warm up on standstill smoke comes out until its warmish then nothing comes out.
Driving performance is great no loss of power, I've checked the boost hoses and apart from a little oil residue nothing. Have replaced the MAF, Temp coolant sensor and boost thrust sensor. Engine is clean and now I'm not sure where to look.
The car has a full service history and has done 143k with cambelt done at 110k.Coolant is clean and EGR not sooted up.

Any pointers and I would be most grateful.
Thanks.
