gearstick knocking/vibrating

[megsal]

Hi

I have just brought a new 'Megane 1.9dci saloon' [08] and after 1000 miles i have now noticed that 'sometimes' the gearstick makes a knocking/vibrating when in first gear and your foot off the clutch i.e just rolling along in traffic; the noise is quite loud at times but does not happen all the time; took to renault dealer, but typically it chose not to do it whilst there!!! Does anyone have any ideas, the dealer has no idea, and it's starting to really bug me......

It might be an engine or gearbox mounting past it's best. I'm sure I've seen a post somewhere about colour coded engine mounts that are stiffer than OEM equipment.
