I have an 04 one convertible . Just bought it noticed that there is a clunking noise when clutch engages or released and also when I tap accelerator. clutch still clunks when engine is off and In neutral. I have read that this is a characteristic of the type of gearbox it's only a quiet clunk and apart from that gearbox seems fine . Has anyone else experienced this or is it normal and I'm being silly? thanks
