Am told the -- sound-deadening, or is it just to stop the cover from rattling? -- foam that's inside the plastic cover mounted on top of a (2.2 in this case) HDi engine is not listed by Citroen as a separate spare part.
The plastic on ours is still fine, but the dried-out foam isn't.....
Does anyone know where to get some foam of the right size and type that could be DIY substituted?
And does it being there make much difference anyway?
