Hello everyone
We've had this car from new and I think it was last year that we started getting white smoke every now and again. I just always wrongly assumed this was a regen, but I now believe it's something else.
This morning it was pretty cold 0C. Car started up OK, but maybe about 2-3 minutes/half a mile down the road white smoke for several minutes when driving on 30mph roads. When I stopped and was stationery it stopped billowing out (but was still smoking a bit), but then once I drove off again, it resumed. It always stops when the engine starts to get warm and then it's totally fine. The smell is like a bad diesel smell, so I believe it is unburnt diesel fuel. This is the same pattern every time it happens. Only ever happens when the engine is cold and seems to be exacerbated when it's very cold outside. It does still happen in the summer months though. Seems like it's happening more though as time goes by and when it's cold outside.
I've also noticed recently that when the car is cold the automatic gear changing can sometimes feel a bit sluggish and not so smooth.
There are no errors messages and the glow plug light does light up momentarily when the engine starts, but doesn't stay on.
Driving profile is very short school runs in the morning and afternoons with longer A road/motorway journeys at the weekends.
Did a lot of searching this morning and glow plugs seem like a suspect. Is this most likely to be a glow plug problem based on the pattern?
Many thanks
