Ey up, thanks for looking and for any help.
I've been having a bit of trouble with my 57 plate, 112,000 miles Focus. It's smoking while I'm accelerating. I've had it in 2 garages (which I won't be gong back to) and both of them said they couldn't find anything wrong with it.
It only happens when the engine is warm, there's no loss of power, no error codes but if I'm on the motorway and I put my foot down the car behind vanishes in a cloud of white smoke! It's fine when I'm tootling along and maintaining speed but soon as I want to go faster there's a shed load of smoke.
The exhaust is fine (or so the 1st garage said) there's no cracks in any pipes (so the 2nd garage says) The 2nd garage also said they'd had it on the rollers and couldn't see anything. As I was leaving one of them said something about the DPF doing a regen all the time but wouldn't I get a loss of power? And would it fdo it every time I put my foot down?
I'm about £100 in for manual labor and still none the wiser.
