Hi All,

Firstly, thank you for taking the reply to reply to my messages it's greatly appreciated.

So the update:

1) Glow plugs done and she now starts when cold beautifully and is very smooth on idle.
2) I have driven the car today for about 40 miles and the DPF Soot Filter Full warning message came up at the end of the journey... The car was consistently smoking once the car has been stationary and idling for 5+ seconds - when you rev and pull away there is a cloud of smoke.

Oil is clearly being burnt but on throttle off or acceleration there appears to minimal smoke (if any) it is just after the engine settles on idle and then revs.

Any comments on this behaviour?

My feeling is that it suggests the breathing system(?) as with the rocker cap off there is a loud popping (I have checked the vacuum to the engine mounts and this is not the problem as they hold vacuum).

I have a 600-mile journey planned in a couple of weeks so I need to get to the bottom of the cause - help is of course greatly appreciated.

Nigel.
