Hello.
I have owned 4 S54 cars but I cant remember if the idle was the same on the M3's?
When I start my car when the engine is cold the idle is around 1100-1200 RPM for about 30 seconds until it goes about normal 900 rpm.
The reason I am thinking about this is because I fitted Supersprint Race exhaust so the car sounds so much that I wake every nighbor every morning, haha
when the idle has settled its almost quiet.
I dont remember the idle with the OEM exhaust.
Is this normal? 21K miles on the car/engine.
