I am a newbie.
I took home an 01 540i with a Dinan 4 package and 37K miles yesterday. What a car. This could potentially be I first BMW.
Anyway, I have not officially bought it yet, until I get an independent inspection. Last night after driving it around for 2 hours, the car would make this strange noise while idling and the clutch was not engaged. When the clutch was engaged, I couldn't hear the noise.
This morning, I went outside to warm up the car. While it was warming up, I didn't hear the noise. Driving to work, I still didn't hear it again.
I am afraid that when I bring it to the inspection this afternoon, the strange noise at idling will not occur. Then I need to decide whether to purchase this car.
What do you guys think the idling problem is? Is it a major transmission or clutch issue? Any ideas how I can make sure to reproduce the problem?
All help would be appreciated especially since I need to make a decision this afternoon.
