My Rover 400 spews foul smelling exhaust fumes, at all revs and cold or hot. Can't describe the smell as anything specific but any cars behind me soon keep their distance! She runs like a dream, have had new exhaust pieces fitted and CAT apparently not needing replacement; passed recent MOT first time. Does not use water nor oil, no water in the oil. Had a recent service and no problems found. Any ideas?
Thanks much for running this site. If I can donate via my PayPal account, will do so.
