Just wondering if anyone has any ideas as to what this could be.
Getting a loud heavy metallic rasp, which rises with the revs between 3500-4500. Would remind you slightly of an E46 M3. Happens in every gear, on rising and lowering revs, foot flat down, or revving lightly. Has been fairly quiet before now, but got a lot worse in the last few weeks.
I've had look for loose heat shields and can't find anything, though this may be different when the revs are up.
Car's driving 100%. Not heavy oil use, smoke, etc. Just this horrendous noise.
I've had a look around online, and can't find any definitive answers. Have heard of actuators/wastegates giving bother on mk6 GTIs between 1800-3000rpm.
Car is an 05 GTI DSG. Revo stage 1 engine and gearbox maps.
Any info / things to look out for would be great.
