Obviously now we have cold weather and you will have some condensation in your exhaust and it is normal for car to get white smoke when you start engine first thing in morning so it will get rid of condensation. But if your engine is warmed properly and u still get white smoke under heavy acceleration it's mean is something wrong with engine.

Hi Damtom,
It's only happened once, but to be fair, I'm not a boy racer and it could be that I have not previously put my foot down as hard before. The engine was fully warmed up and I had just come off a major "A" road where I had been doing a steady 60 mph for half an hour or so. Navigating around a roundabout and turning on to a duel carriageway road that I knew, I was behind a slow car and so pulled out to overtake. As the 70mph duel carriageway ended in approx 200 yards, I excellerated hard and the auto gearbox smoothly pulled me away and I easily passed the slower car within the distance before I had to reduce speed to 60mph on the single carriageway. Glancing in the RVM I saw huge plumes of white smoke billowing behind my car, which stopped when I maintained a steady 60mph.
White smoke to me, relates as you correctly say, to water being boiled away and that amount of white smoke would only happen with a blown water jacket gasket, something that used to happen a lot way back when - however, the white smoke would then be seen all the time thereafter. Or could it be that the engine was in the process of doing a regen and I blasted the DPF with fuel, causing the filter to burn clean? Obviously, the more fuel is burned, the hotter it gets, thus the exhaust can get super hot at such times ?? Is this the answer to cleaning the DPF? Bye the way, I only use BP Ultimate, which claims to burn more efficiently anyway. Any thoughts would be appreciated, please
