I've been searching online for sometime now and i cant seem to find the location of the oil pressure switch. Could somebody please help me with this ? Its an 2012 Jetta (A6). The car has been blinking the oil pressure warning (red), but i've still been driving it for over 3months now. The car runs the same as always, so i thought maybe its the oil pressure switch? The oil pressure stays steady at 90, but i cant think of anything else that might be the problem. Warning light only comes when the engine has been sitting for a while, 8hrs maybe. And it only comes in the start of the drive, and goes away in few minutes, and doesnt come for the rest of the day anymore.

What to check next

Diagnostic guidance. Suggested checks and possible repairs are separate from the owner's reported results.

If the red oil-pressure warning appears, stop safely and switch off the engine. Arrange assessment rather than assuming the replacement switch has resolved the warning. Have actual oil pressure and the warning circuit checked against the service information for the engine code. Confirm the replacement switch's application and record whether the warning recurs. The owner's location description is not a substitute for the matching component diagram.

Yep good call, it sounds like the oil pressure sensor is bad, here is the location so you can swap it out, you may need a special socket to remove it BTW. The sensor is near the oil filter. Can you please doble check the engine size, also is this a euro car?

Thanks for letting me know, it is described as being under/behind the intake manifold area. Use a flashlight to inspect and let me know.

Got the pressure switch replaced yesterday. Fairly easy job, just needed a longer socket to tighten the switch in place. It was located at under some pipes on the right side of the engine. Only found it trough the single wire that was plugged in. Didnt need to go under the car. Thanks for the help!

Discussion summary

Oil pressure switch location?

The owner of a European-market 2012 Volkswagen Jetta 1.4 TSI described a blinking red oil-pressure warning after the vehicle had been parked for several hours. The discussion focused on locating the pressure switch. The owner later reported replacing a single-wire switch accessible from above beneath pipes on the right side of the engine.

Reported outcome: The owner reported replacing the switch but did not explicitly report that the warning stopped.

The reported reading of '90' had no stated units, source or test conditions and cannot establish adequate oil pressure. The export does not establish the exact switch specification or a completed pressure test.
