3.0 tdi Smoke on Cold Start-up - Problem ?
Discussion
I note during winter my 3.0 tdi A6 2009 emits white/grey smoke on start up which smells quite acrid. It clears straightaway & doesn't omit anything when driving I am aware of.
Its a well maintained unit at 80k with fuel filters etc regularly changed & oil changes, premium fuel etc.
It does unfortunately these days get used for shorter journeys on cold but at least once weekly it gets a good blast.
I am sure it didn't do this last winter & only noticed it below 7degrees when glow plugs on.
Is this normal for these units /diesel in general or does this suggest a pending problem?
