I wanted to know if anyone else has experienced this problem. I own a 2001 530i with a 5 speed manual transmission. The car has 97,000 miles and is in very good condition. 3 times in the last 6 months when I have been at a stoplight and released the clutch to accelerate nothing happens. The car just sits there and the engine revs. I push the clutch in once or twice and everything is back to normal. The last time this happened the car started to move slowly and repeated the same problem through 2nd and 3rd gears as if the clutch was slipping. This has happened 3 times in 10,000 miles and the rpms seem fine while I drive. Any thoughts or suggestions?
