Your Golf’s oil pressure sensor measures the oil pressure mechanically, and converts that reading into a voltage signal that the PCM (Powertrain Control Module) uses for the oil pressure reading. This reading is what you see on your oil pressure gauge and triggers the oil warning light. P0522 Quick Facts

What happens when the oil pressure is low on a Volkswagen?
Volkswagen Golf Low Oil Pressure: Diagnosis and Causes. May 29, 2019 by Jason. One of the most serious issues that can happen to your Volkswagen Golf ‘s engine is if it ends up with low oil pressure.

How does a VW oil pressure switch work?
Oil pressure switches are typically used as an actuator which directly activates the oil warning light in driver dashboard when the oil pressure in the engine will fall below the preset critical level or brings a signal to the ECU (engine control unit), so to be warned about low pressure of engine oil and prevent ...
How does VW oil level sensor work?
As the sensor continuously monitors the oil level throughout the entire engine operation, it prevents the oil level from falling below the minimum oil level during engine operation and hence interruptions in the oil film (which would result in engine failure).
How does an engine oil pressure sensor work?
Standard oil pressure sensors work by displaying a warning signal when the oil pressure falls outside of the set range. Two important components to the oil pressure sensor include the spring-loaded switch and a diaphragm. The spring-loaded switch is connected to the diaphragm that is exposed to the oil pressure.

Can you drive with a faulty oil pressure sensor?
Driving with a bad oil pressure sensor is not necessarily a very good idea as it prevents you from knowing if there is a problem with your oil pressure, which can hurt your engine and potentially put you and your car at risk. Although, if you absolutely have to, you can drive.
Does oil pressure switch affect fuel pump?
When the engine stops running, oil pressure drops, the oil pressure switch opens, and the relay de-energizes. This provides automatic fuel pump shutdown after a crash or engine failure and prevents the fuel pump from running if the ignition remains on.
What causes oil pressure sensor leak?
A bad oil pressure sensor may cause your vehicle to leak oil. Oil pressure sensors are connected to oil sending units. Therefore, they can develop leaks. If your vehicle's oil pressure sensor is leaking oil, you should replace it as soon as possible.
What causes low oil pressure in VW?
The most common cause of low oil pressure is too little oil in the engine. It could also be caused by issues like wrong engine oil type, clogged oil pickup tube, or a damaged oil pump. You should always check the oil level and quality first.
What is the difference between oil pressure switch and sensor?
The oil pressure switch simply activates or triggers the oil pressure warning light display when low oil pressure is detected. While; An oil pressure sensor is responsible for measuring the actual pressure of the oil and sending the corresponding signal to the oil pressure gauge for appropriate reading.
How do I reset my oil pressure sensor?
Insert the key into the ignition and turn it to the “on” position without starting the engine. Depress the gas pedal slowly three successive times within 10 seconds. At this point, the system should have reset. You can verify by turning the ignition off and then on again.

What if I put too much oil in my car?
When too much oil is added, the level in the oil pan becomes too high. That allows a fast-moving lobed rod called the crankshaft to come into contact with the oil and essentially aerate it. The result is a foamy, frothy substance that cannot properly lubricate the engine.

Air in Oil. If the oil level is significantly lower in the pan than it should be, air can get into the oil pump and aerate the oil. Think about it like the foam on a cappuccino or beer. It’s the same liquid, but has totally different characteristics when foamy.
What happens if your golf sensor goes bad?
Modern vehicles use an electric oil pressure sending unit. If your Golf’s sensor has gone bad, it’ll shoot a false low pressure reading to the ECM. One of the first things that people do when they have the low oil pressure light is to change out this sensor to see if that rectifies the problem.

If you need to replace your oil pressure switch you will need to have a little patience
The switch is not expensive or all that difficult to get out but it is in a really tight spot and you must remove the wiring harness connection before you can remove the switch. Give yourself plenty of time.

Figure 1 With the car safely off the ground you will need to remove the engine tray (red arrow) and right side lower wheel well panel (yellow arrow). A great many of these car have had the engine trays and front side panels removed over the years and not replaced.

Craps you up when that warning buzzer goes doesn't it? My old Scirocco used to do the same thing (1.8ltr) and the switch was goosed.

Ok changed the switch and the car was fine and then the second time I drove it the STOP sign and oil pressure sign come on again!
Rustynuts
Could be the oil pick up pipe in the sump is sludged up. I think they have a mesh filter covering the end. Dropping the sump and having a look could be the next step for me.

I had the same sort of problem on a Mk4 Golf 1.6, the problem was eventually diagnosed to a faulty engine speed sensor, It gave me serious heart issues when the "STOP" lit whilst I was passing a truck uphill!!
Rustynuts
The "STOP" signal will flash up whenever there's an issue, but it's the oil pressure light accompanying it which indicates the problem here.
colinc
Exactly my point. mine said "STOP" "oil pressure" but it was actually a fault with the engine speed sensor
harminder
Had it checked out by a VW specialist and the garage found nothing wrong.
