Hi All,

I have recently been down the M1 in my Focus MK2 TDCI 1.6 (55 plate) and noticed that when i lift off the accelerator i see quite a bit of white-greyish smoke out the back! however, this only starts to happen after about 30-40 minutes of driving which makes me think heat is an associated factor?

The car has recently had its turbo remanufactured about a week before this happened. I also had the DPF removed and ECU remapped but the carbon smoke associated with that job has pretty much gone now so i don't think its that.

Does anyone have a clue what may cause it to do this when i let off? Im scared the thing is about pack up.

thanks in advance

Lee
