This is still bugging me. The clutch still has plenty of life (as far as I can tell!). It's weird how it makes the noise with the engine on in neutral (when you press then release pedal - single clunk), but not when the engine is off. That definitely rules out engine/gearbox mounts I would say. Pretty sure its the clutch release bearing?
While were on the subject, what's the best budget clutch to go for? I want to stick with OEM DMF but want something to handle my stage 1 remap and potentially stage 2 later this year.
