V6 4motion problem

[Happy Eater]

I have a Golf V6 4motion w reg which is ok most of the time but...

sometimes starts but then smokes loads, missfires, loses power and then ten minutes later restarts perfectly. the engine management light also comes on

It pulls well and when its good its very good.

Any thoughts on the issue - it is in at the garage at the moment due to be Vag-com checked.

My guess is that you've got a knackered coil-pack. A common problem, but an easy fix.

Good luck getting it sorted.

Does your problem coincide with rainy weather ?

Early ones had a coil pack instead of seperate coils.
In damp weather mine used to misfire when first started (although I never noticed smoke).
I took the coil pack out and there were loads of harline cracks on the surface which I covered in epoxy resin (after some googling).
Solved the problem permanently.
Worth a try for £5 as the pack itself is around £150 iirc.

Thanks for the responses
It does seem to happen when its wet - either snow or rain.

If I get time today I will check it out.

Thought Id let you know,

Replaced the coil pack today - drove in a lot of puddles all seems fine.

Many thanks
