Knock from engine ? Help

[Ashmc]

Car is 2.0 TDI 130k on clock , car is now knocking in idle and the knock goes when clutch is pressed , the AA said they’re 90% sure is the fly wheel !
Do you think he’s rite ? Also how much should I be looking to pay fitted

Thanks in advance

Does the clutch have to be replaced also

It appears likely to be failure of the dual mass flywheel. A common problem. As for replacing the clutch at the same time; Yes - Absolutely! It would be daft to remove the gearbox for anything (especially replacing the flywheel) and not to replace the (part worn) clutch at the same time. Probably worth replacing the clutch slave cylinder at the same time too. Just to throw in a suggestion. A friend owned a 1.9 TDi on which dual mass flywheel failed at 70k miles. It exhibited exactly the same symptoms as you've described. He replaced it with a solid unit. I 'know' it's not recommended (before everyone shouts) but he didn't want the problem again. The car then ran on to 250k miles with no clutch or flywheel problems and no obvious evidence of the different flywheel.
