Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

When my car (03 MY C2 tip ) is warm ,there oil pressure is now showing 4 bar at 2000rpm rising to 5bar above that speed ? At idle it drops to 3 bar. Been off to Parr who checked it on the computer and no problems showing. If I switch the engine off and back on again it settles back to normal but then after a short while goes back to doing the same.Engine oil is Mobil 1 0-40 and it seems to use very little of it . The engine has only done 30K and properly serviced . I have not had to top it up at all for some months . Only other things that may be related are that I have the lumpy idle problem quite often and there has been a strange rumble and vibration (like a knackered wheel bearing ) from the rear of the car but this too has been checked and all drive links ,suspension and bearings seem to be tip top !? The assistance of all you wise ones would be much appreciated .
