Hi all have had a rattling noise from the rear of my engine N47, thought it was the dreaded timing chain, but one morning at the caravan the engine sounded good no rattling but since then getting a slight vibration through the gear stick and gearbox, also a whining noise on acceleration so now thinking dual mass flywheel. I know you cannot diagnose dmf until you take it out so thinking just change the clutch and flywheel as not sure if it has been changed before but to change the flywheel for a single mass along the lines of solid flywheels where good on old fords why not 2008 Bmw 5 series ?
Any thoughts ?
