Miss-fire when cold.

[Jochen]

Hi Leon owners,
Got a small problem with my Leon Cupra, 51 plate.
When started from cold, it will miss fire for a few seconds on and off and then as soon as the secondary air fan cuts off it will be perfect, no problems when hot or when driving on the road.
There are no faults stored in the engine e.c.u, just wondering if any one else has experianced this and/or had it rectified?
Not a coil problem, as they have all been checked on scope/5051.
Cheers,
Jochen.

During that time misfire recognition is disabled (yes, I have checked it) , it's normal in most of the VAG cars.. it's running rich for 1-2min until it warms up.. it's automatic cold start choke.
