idle rpm and DCT
My M was repaired, and new engine is under hood.
I notice that after the car is completely warmed up and DCT is in D1,
idle rpm is steadily at about 770~780rpm.
If I remove DCT to neutral, rpm is down to about 650 and stay there.
And when DCT is in D1, I put brake pedal, idle rpm is down to about 650 and stay there, too.
Sometimes, always 650 in all condition.
Is this normal?, just curious.
