Hi all just had a phone call from a friend in a 2008 120d m sport he claims he tried doing a pull and as he dropped the clutch he heard a loud bang and the car won’t move, it goes into first and when he realised the clutch the car didn’t move or stall and when the clutch is down he can hear a clanking noise coming from the rear, if anyone knows what the problem or problems could be please let me know greatly appreciated.
