I am driving a 56-plate Mondeo 2.0 TDCI with around 44,000 miles on the clock. I am generally happy with it apart from the clouds of white smoke that are kicked out when I hit the accelerator (in 1st, 2nd, 3rd and 4th gears). I am used to the occasional puff of black smoke and accept this as normal, but surely lots of white smoke isn't? Or is it?

Anyway, I took the car to a Ford dealer to have it looked at and they found that the EGR was sticking open. They have replaced it and believe that will fix the problem. Do does anyone concur? I have to say I was surprised by the 'fix' - I was expecting to be told that the oil seals around the turbo were worn.

The experience I've had is that a sticking EGR that sticks open causes loss of power and clouds of black smoke, when it's stuck shut (or blanked!) smoke is reduced from normal and engine pickup is smoother, I can't see where white smoke would figure either way?

I'll keep an eye on it when I'm next on the road. It is most apparent when doing 50-60 and then flooring it. But I suspect I'll be back in the dealership soon Its under local dealer warrenty for a year so it may just be that they will just string me along until the warrenty ends when they'll 'discover' the real problem.

Worn turbo oil seals would usually cause blue smoke but to rule it out, if you can get to the intercooler and just check for oil spray inside it. Sometimes get white smoke from water in cylinders but not sure on diesels.

Could also just have needed the EGR cleaning out. Mine needs doing every 6 months.
Dunno if we have a bad batch of fuel in the UK at the moment but I've noticed a lot more smokey diesels in the last week than normal, inlcuding my own.
