Hi Folks.
Had a problem with uneven tick over when cold. Runs great when warm and returns 54 mpg, no smoke and gets regular services.
I changed the air filter again yesterday as a matter of course and decided to remove the top of said filter housing to clean it. I noticed that the clip that holds the rubber hose after the MAF sensor was missing. With my limited knowledge of said 130 TDCi I would have thought that this could have caused the uneven tick over? I have cable tied it at the moment until I can get a clip.

It does seem better today on a 75 mile motorway run, will keep an eye on it

Thoughts please!!
