White smoke is usually water - how are your coolant levels? 2007 Zermatt Silver TDV8 Vogue SE - now sold but was a great car! |

Over fueling would be black smoke im afraid, the DPF filters normally have a pressure sensor before and after that sense when the filter needs cleaning and a Re Gen is forced by it running a lot hotter in the filter to release some of the carbon deposits. Sounds more headgaskety to me One day your life will flash before your eyes......................................make sure yours is worth watching!

white grey can be Turbo seals or head gasket but mine gives out white grey smoke from the DPF auto clean every 1500 miles or so for 1-2 mins , my wifes BMW335 does the same thing Far to many gone... |

I really wouldn't worry...it is under warranty - just keep driving it if it's only intermittent...

RR has been into the local dealers it has a known fault with an oil seal around a turbo that affects certain 4.4tdv8 engine which is allowing oil to pass into the DPF hence the smoke

So a dealer tech is going to drill a hole into the block to provide a new oil feed for one of the turbos?!?

Mine had this problem some 12 months ago and at that time the first action was to replace turbo. That was done and then DPF failed! Which pointed JLR in the direction of the problem proper. It seems that the issue is that the turbo can under certain circumstances force back the oil that has passed through the bearings through the seal because the relative height of the reservoir is too close to bearing height. This is the fix to make sure the oil drains properly. 2019 D5 HSE Lux SDV6 Indus

I had a similar problem when accelerating and would look out of the rear view mirror to see plumes of white smoke all over the car i had gone past. Took my TDV8 (11.5MY) into the dealer under warranty and it was repaired as a known problem on the 4.4TDV8.
