Hi ... Jeep Grand Cherokee first reg Oct 2006, 3.0 diesel CRD Limited ... oil pressure light coming on momentarily .. only when engine warm for maybe 20 minutes/half hour ... ok at 2000 revs in top (auto) but it lights/pings at 2500, or if downchanging to 4th or 3rd gear and revs rise by 500, same again. Happens whether towing or single. Usually only stays on for maybe 2 seconds but a couple of times after giving the engine some stick at 3000 revs it has stayed on for about a minute then gone off as soon as revs drop to 2000 again. Correct oil etc, recently serviced/filters etc.
I'm getting the sensor changed tomorrow just in case but not hopeful. Any advice?
