I am wondering if anybody has some advice.


I have a S80 with a D5 engine 2008. I recently had the cam belt and full service carried out by an independent Volvo specialist. On getting the vehicle back I have had a couple of problems. Engine poor starting, this was rectified by new set of glow plugs. Now I have the engine service required light coming on. At first the lever to the air flow sensor had become detached, this was renewed. Then after a few miles the light came on. The fault code shows high voltage at oil level sensor, this is a new code and was not there before the service. Can filling with the wrong grade oil give this fault?
