I've just rana diagnostics machine over my car, asI am getting bad fuel consumption (34.7 mpg) and my reverse sensors have ceased working.

These are the results I got.

4222 Glow Plug Cylinder 2
4232 Glow Plug Cylinder 3
4242 Glow Plug Cylinder 4
4501 EGR (Exhaust Gas Recirculation)

Nothing to do with my reverse sensors though?

any suggestions?

Strange why it never found anything regarding the reverse sensors though. Is there a guide knocking about on cleaning EGR valve?

Also would this be the cause of low MPG?

Whats the other filter that is recommended to be cleaned on the 320d? I can remember reading about it but cant remember the name. I may aswell do it all whilst I have it in pieces.

Cheers Neal.

Ive just been out and tested for clicking on the reverse sensors and all seems well, each one of clicking.
