08 Golf Grinding Noise

[Jon44w]

Hi would anyone have any idea why I have a little grinding noise when setting off in first and reverse but no other gear


It only happens on a slight hill start and with a little rev. I can drive off normally without it happening


I’ve just put in a new dmf and concentric release bearing


It’s an 08 golf 2.0 Tdi 6 speed

Going to check engine mounts tomorrow but if anyone has any thoughts please let me know


Many thanks

I should add the noise is very quick approx half a second and is altered by the revs and speed of clutch release

Did you use all new gearbox mounting bolts?

[Jon44w]

Yes new bolts used, although I should add the noise description of grinding maybe isnt the most accurate. Its more like if you say "errrr" in as high a pitch as you can.

Although interestingly I just found a similar old thread on here (see link below) where a poster says the dealer thinks its turbo stall when setting off. So I took the car for a drive and went above my normal driving style. Over 3000 rpm in 4th gear going up a hill it went into a no warning light limp mode. Vcds check - overboost. Ive seen this exact fault before and previously had to replace that turbo because of metal fatigue in the turbo blades. Ill take the turbo off this one and have a look but is it really possible this could be responsible for the noise? It doesnt seem like the turbo could make this noise but then a Vw tech would know a lot more than I would. Any thoughts or previous experience appreciated.

Grinding noise on set off

Take the turbo off and have it rebuilt locally.

Will do crasher cheers, will keep you up to date with what happens, many thanks for all you help in this thread and loads of others I dont post in.

This problem was sorted - Im guessing it flywheel noise on a new DMF but if not it was something do to with the clutch kit. Replacement kit fixed it.
