How many mile since? What has the car done since the service? Has the coolant level gone down?It’s only just had a full service
That's probably what the problem is, being started and not up the running temperature more than a few times. When I sorned my 2.0Z3 when I started it every few weeks it filled the driveway with steam/smoke . The filler cap always grew some crap like yours has but after being used "normally" it cleared up right enough. Has the coolant level dropped?50 miles max.
The M54 engines do this mayo thing a lot.Here’s what I found
Looking goodAfter changing the boot lid and getting locked out.
I had fitted the rear wings. New aerial grommet. Rear lights and put the boot all back together Inc another boot lid. All with new fixings from bmw.
I was pleased with myself.
Thats normal on the 6 pot as is the smoke when its been sitting around doing nothing, the handbrake sticking is also quite normal, in future leave the car in gear with the handbrake offHere’s what I found
