Hello
Posted help in working out what was causing a low sounding knocking noise (sounds like plastic rather than metal) coming from around the bonnet area when driving over routh ground.
Mate of mine looked at it today and thinks it could be the case that covers the engine over the filter etc
There appears to be a screw or bolt missing ???
any idea were i could get one?

Are you trying to secure the Td4 caustic cover on the engine?
