So my Fabia VRS has always had an issue with idle, an intermittent rattle with shaking however it stops completely when clutch is pressed down and when driving. No performance issues at all, still a little missile! Mileage is at 107k with a bible of service history. Upon research I’ve discovered it likely being due to input shaft bearings, could this also be down do flywheel or clutch? I’ve also read that a worn alternator pulley can cause this issue…

Any input is greatly appreciated!

Thanks

If yours has a DMF then it could very well be flywheel thats causing rattle/shaking. If its a solid flywheel it may be the clutch release bearing or clutch related. As you said it may also be the input shaft bearing. If its any of the above I reckon the Gbox would have to come out to check.

Thanks for the reply! I’ve got my MOT coming up so currently replacing shocks, springs, brakes etc… I’ll probably just get a full clutch kit with DMF and throwout bearing and do it over the coming weeks. If the noise remains then I’ll know it’s likely the input shaft bearing!

Check it has a DMF some of the MK1 had solid flywheel. My sons petrol has solid but I think from memory my folks old 1.9tdi had DMF. If its a failing DMF then it should be fairly noticeable once gearbox is out. If the flywheel is ok then it might be worth replacing bearing at same time as the gearbox will be out. I replaced the slave cylinder on my sons when I did the clutch as his was starting to leak slightly.
