It's normal it is vapor. Like mine when I run on the Alps. During a hill down the exhaust pipe came cold, and when you push the Throttle the warm gas produce vapor..... Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

Thanks again dgardel!
Just to know, Is it happen also to you during a descent after a cold start up with engine cold and in 3th gear (engine brake) that some light blue smoke go out from exhaust? |

It happen again! worst!
Today I went out with local club on the mountain unfortunately the weather was terrible heavy fog frozen rain, very dumpy weather! On they way back we went down on sky trail, I decided to engage first low gear, during the long descent (40 minutes)in order to use engine brake. After 15 minutes during descent the coolant temperature dropped to minimum. When finally I arrived at the descent end on plain, I disingaged low gear, and start too drive normally on normal street, after a couple of minutes a white dense smoke like a vapour train came out from exhaust, I stopped and also at the minimum smoke came out. It stops smoking and all turned normal when after some minutes when I accelerated. The smoke was white dense heavy burnt smell. I did all the ECU update and I changed two times EGR. Anyone soffered similar experience?  |

Check your sedimenter for water.

NOt sure but quite normal on diesel engines. Some trucks use a blind-type cover when going downhill in cold climates. Anyway, the other day I heard a chap at the stealer complaining about the same issue (brand new). Puma 110" SW

Couple of years ago when I was travelling with my camper (then on Ford base using same 2.4L engine) I also experienced this as I went over the Alps.
After a long climb to the summit of a pass (something like 2300m, don't remember exactly) we made a stop there for about one hour to have lunch. When we started driving again downhill the amount of white smoke was just increadible. Funny enough this was only visible when the accelerator was pressed down; when driving downhill and using the engine for braking nothing could be seen. I reported this to my garage (Ford) but never got any decent explanation as to what could have caused this. At that time the vehicle was also quite new (about one year). Never experienced this again  .
Note that the outside temperature at the mountain pass was pretty cold (but not freezing). Once the engine was warm again this white smoke stopped (could also have been because by then we reached much warmer air). |

Peter when it happened with your camper, can you remember if the similar vapour white smoke was also bad smell, like when you burn a plastic panhandle?

Even with normal temp on your engine, at downhill with 0 throttle, the amount of heat produced by minimum diesel injected producrs nearly no heat, so I guess it is cold diesel being coldy burned (plus vapour). I would no worry. I doubt any valve seal is wacked. Better ask a real diesel mechanic or LR customer. Puma 110" SW

this has started happening with our 07 110 ...
Thick white smoke with a plastic smell till it warms up -no loss of power, no use of oil / coolant air temp has been arround 0'c - but this is the first time I've seen it. It's very embarrasing pulling away and watching the world vanish behind in the mirror!!

At 0C it's impossible...... May be a bug on ECU SW for the injection advance table Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition
