I have had my scooby a couple of months first one (great car) but a couple of weeks ago the engine started making a slight grinding/knocking noise checked oil, altenator etc but cant make out where noise is coming from, sounds like just below a/c pump . Also if you hold the fuel line you can feel it pulse is this normal or is pump on the way out have I bought a dud one. paid 2700 and was the best of a bunch no oil leaks etc. I live in Isleworth west london does any one no of a good garage that is honest and not going to cost the earth. Any help would be great.

 

Grinding and/or knocking! Get it looked at asap..
