So the light came back on again. Second time in 6 weeks. Had recall work done. Light came on when I switched lanes then accelerated. Dealer ran a diagnostic and said it could be this or that. May be some sort of valve and may need to pressurize it to see where, if there is a leak... Their comments....
READ AND EVALUATE FAULTS (DIAGNOSIS OF CHECK ENGINE LIGHT)
FURTHER DIAGNOSIS TIME NEEDED (FURTHER DIAGNOSIS TIME NEEDED TO CHECK VACUUM LINES AND ELECTRONEUMATIC SOLENOIDS)


Long story short. He said don't worry until light comes back on and is persistent. As of today, no light.

Also does the hot weather affect the twin turbo acceleration?

I just had the same experience last week. I immediately took it to my dealer(based on other post about this topic) and it was the Vanos. It was replaced..the car runs great now...no more rough idle, long start ups or rattles.

I had that warning a few times. A broken vacuum line was replaced, and I've been good to go since. The dealer did a "smoke" test.
