A few month back i was greeted with a knock at idle when i started the car one morning. It only happens when to engine is cold and soon goes away, if it does it at all that is. It only does it at idle and stops if you rev the engine, but starts again when returning to idle. It seems to be an intermittent noise. Sometimes it does it, sometimes it doesn't. I've not noticed any change in performance and no eml either, it just doesn't sound great and can't be normal. Also poked my head under to bonnet to but can't seem to locate it so im at a bit of a loss really.
Any thoughts are welcome!
Cheers Alex
