Hi
Have just purchased a 1999 Golf V5 Auto and recently on cold wet mornings it struggles with power in low revs 1000-2000. When I accelerate when the engine is cold it judders / stutters before finally the power is delivered in a rush. It also splutters on tick over.

When the engine is warm its smooth and acceleration is perfect.

Has anyone got any idea what the problem might be before I start throwing money away guessing. Please bear in mind I am not mechanically minded, so keep it simple please!

Any help most welcome.

Have just go my VAG COM cable and have scanned for errors:
