    This f**king car is begging to annoy me now.
    Just finished work started the car up fine no problem. Go to pull away on the main road and filled it with blue/white smoke. Hasn't done it since.

    Checked your EGR valve lately? Could be sticking open/closed.

    White smoke is normally coolant/oil related and blue tends to be more fuel related ?? possibly just leaky valve stem seals !

    had it been idling for a long time?

    Could be valve stem seals if so.

    Yeah was waiting for a mate to walk out of work too so probably 5-10 minutes, what options do I have to sort the stem seals?

    Cheers jay

    Little update/research it hasn't kicked out any smoke since last Saturday been told to check under oil cap while it's running for excess pressure and it has a lot of pressure. Which could hopefully rule out stem seals? And possibly something much easier.

    really?

    Blue - Oil
    white - Water/Steam
    Black - Fuel (i.e too much of it)

    at least that is what I always went by

    I am no AA mechanic but you have to ask yourself where that pressure is coming from?
    usually pressurised header tank and smokey exhaust is an immediate check for head gasket trouble.

    overheated recently, run low on coolant?

    Nope not overheated once, coolant is fine too. As it hasn't done it before or after that 1 occasion it's hard to pinpoint so unless it happens again I'm not going to worry too much.

    I'll try to get my hands on vagcom and see if that comes up with anything.

    Get a sniff test on tge coolant bottle to check for hydracarbons this will be an indication of the head gasket.
