Hello Guyz,
(Car: 2001 BMW 325i)
I need guidance on the following:
- When i start my car engine and specially when its still cold if i put the Transmission on "D" or "R" the RPM start to play and go slightly up and down around 500.
- Same if i leave the car idle for a while i get the same result
- Is it normal that when i go more than 5000 RPM i hear a whistle sound before shifting to the next gear?
- Also when i first start the car and its still cold i hear a knocking sound in the Air Pump for a minute then the sound is gone. Check following Video to hear the sound (
