I had a similar problem with my G60 when cold, replaced Lamda sensor with a new genuine VAG one and this sorted the problem, cheers Dave

Post up some resistance figures across the 2 pins on the blue Coolent sender whilst running up from cold. Lets see if its that thats playing up.

... or just replace it as they're dirt cheap and worth replacing anyway.....
