Wheres the oil pressure sensor?
 

I need to know its bugging me. Everytime I get on it my OBD flashes the red light. It hasnt worked since I got the car the gauge reads 5 bar before I even start the car.

have a look on the left hand side of the engine under the top hose.there are 2 switches one white and one black .

He don't have just "two switches" :razz: He have one switch and one big sender that's "two in one" - 0,5 or 1,8 bar switch and sender for pressure gauge. If gauge goes max just when turning on ignition, it isn't connected to sender - or someone connected wires incorrectly - if both wires on big sender is connected, then connect them opposite and take a look if that helped.
