Hellooo, I have a Mk4 GT TDI (6 speed) and for some reason my car now Shakes whilst im in Low Revs/ Hi Gear (It only really happens while I am doing 35/40mph in 3rd). I've tried to Isolate where the shaking is coming from but It does rattle the entire car like you're driving over a rough surface. I really need some sort of diagnosis of what the potential causes? Gearbox? Clutch? Any help Welcome! Thanks people!
