NB 1.8 Cold Start Idle

Hi All,

I have a 2005 mk2.5 1.8L Arctic and over the last few weeks, I’ve had some issues with the idle speed of the engine dropping almost to a stall ~500rpm before coming back up. This ONLY occurs when the engine is cold and the base idle speed is higher.

The car runs and drives fine once up to temperature.

Any suggestions?
