What does the grinding sound like and where abouts is the noise coming from - is it when idling, or when moving?

I get that very infrequently on mine, and I got told it's just a loose heat shield.

clutch release bearing i'd say, there noisy on the mk5, does it quiet'n down when you push clutch in, then when you depress it does it get louder?

Na it just does it now and then it drives fine, pulls nicely and revs as it should, just a horrid noise now and then i fope its heat sheild cos well i cant afford a higher credit card bill lol! i got a credit card for this car when it goes wrong ha, joys of the gti lol! Il wait til summin breaks i think or mit book it in 4 a service then ask them to check it over, how much isa service btw a 36thousand mile one as i bort car from auction for 3450, bargin ina way even after spendin 670 on the car! 51plate! what do i need to ask when there giving it a service as my service history was stolen so im bookin it in anyway as to be sure its ok!

sounds like a loose heat shield...or an exhaust mount needs replacing, is it an aftermarket system?

All standard at the minit, im bookin a service tomorow a big one like changin everything, should be around 220, gona ask to have gearbox mounts checked and rods realighned aswell! they oh me that after spendin nearly 700quid with them lol! showed my dad the noise and to all wonders it never made the grindy weird noise lol, but il leep ya all in date with procedings!

Yeah i no it wont but my mates gets me mots iv had a saxo decat he put it strait thru wink wink lol! theres a company down the road pipe craft that make decats, bolt in ones using the same fixings or similar ones as on the cat, with an induction kit cold air feed a viper iv got to install once silicone hose is bort! Would the performance be noticable?? And noise from the decat, would that be loud???

You would notice the sound of it de-catted, probably not much performance wise though, not on a standard system anyway
