Is this a common fault?  Heavy but intermittent vibration from engine (exhaust pipes shake like a dog's tail).  First complained shortly after purchase and (vacuum) engine mounts were replaced. Now two years later vibration has returned as bad as ever.  Getting dealership even to test mounts is proving difficult as vibration is intermittent and they have not seen/experienced the issue with our car.  Anyone else experienced this issue?

Hi John....welcome to the Club

Does sound like mounts are failing again after two years....if it cured it then it is possible it is the same issue once more

Let us know how you get on with it.
