When ever i take my Mini for long drives e.g. 22 mile trip to work experience, i get a knocking noise, it usually begins about 8 miles before i get there, and only happens when i take my foot of the accelerator, the noise is like a loud thud, and it sounds like its coming from the engine bay, but it has had new engine mounts recently.
Most of the trip is down the A38, with mostly 50 and 40 limits.
I never get this problem when going to college or work, which has 30/40 limits.
John ( Guessworks ) said my strap is missing from my exhaust attaching to the gearbox, so could this cause the exhaust to hit the floor pans?
If so, why does it only do it on long journeys?
