1 - My display screen on a regular basis says: engine oil pressure low, however when I check the oil all is fine, why could this be?
Have oil [ 4.5 litre of a liquid ] in the engine is different to have oil pressure [ pressuired oil via a hydlraulid pump ] in the engine.
However, assuming the engine actually has pressure then its either a faulty pressure switch [ at the back of the engine near the alternator ] or there is a loose connection going onto the body comupter [ located behind the fuse panel ].
BUT if its is low oil pressure the engine will be very noisey/rattley & will soon destroy itself.
2 - I had my car serviced but seems like the service meter or computer has not been reset, can I do this myself? The Owners manaul might explain it or ther eis a Menu option, scroll down to Service, then press + and - buttons together for 10 seconds [ that might resert it ]
