High Idle RPM on Cold Start
Hey Everyone,
Just wanted to run this by the folks here as this is my first AMG and wasn't sure if this is normal.
When I cold start my C43 it immediately goes to idling at about ~1400 RPM. If I then immediately put it in gear it drops down to around ~800RPM.
However, after I've driven it for a bit (not even fully warmed up) its idle goes down to the usual ~500-600 RPM. And it stays there until the car is fully cooled down again.
Is this something I should have checked out? Everything on the car has been running great. I have had no issues otherwise so I just wanted to get some opinions on this.
Thanks,
Zero

Yeah I figured this may just be the engine idling higher due to the cold start temperature. But as I said, its my first AMG and wasn't sure. My last car wasn't a performance vehicle so it didn't vary the idle much between cold vs warm start.
