Hi!
So my 5 year old ML350 has suddenly decided to start idling at a higher RPM 750 when the AC is switched off and 900 when AC is turned on.
This doesn't happen initially when the car is switched on in the morning. But within 5 mins of driving the idling start rising on the higher side (all the way to 900 with AC on)
Since The service centre is not being able to find any fault.
They are suggesting I change the main transmission control. But I am convinced it's a small tweak that's required.
Any suggestions?
