Just off on holiday and driving the e38 one last time before its off to the airport....
The car has been driving just fine.
This morning some faint 'revving' sounds but no revving on the speedo. Went to accelerate and no power, limped to 30 miles and very slow to accelerate. So turned back and the car is now in the driveway. Checked the transmission and placed into reverse, works, then back in to forwards, works.
NO warning lights or codes.
Anyone have some ideas here? Just wondering what to expect when i get it in to bmw next week. Drive chain??? Torque converter?
