VW Golf 4: Persistent 'Olsensor Werkstatt' Message and Flashing Orange Oil Canteen

Hello. Recently, I saw the message "Olsensor werkstatt" and the orange oil canteen flashes. The message pops up when I turn the key to the ignition. I changed the oil because the time has come for it and I also replaced the oil level sensor, but the message still pops up. What's the problem? And where does the cable from this sensor go, because it seems to me somewhere under the battery?

Hello. Maybe this error needs to be removed by service?
The oil level sensing element also works with a temperature measurement, which is briefly heated by the electronics to a temperature above the current oil temperature.
When the heating voltage is switched off, the measuring element is cooled by the engine oil back to the oil temperature level. The oil level is calculated based on the cooling time.
Long cooling time = underfilling
Short cooling time = normal oil level”
Maybe you didn't plug in the plug in the sensor?
"Note: If LongLife is disabled due to switching to fixed service intervals, the oil level sensor will also be disabled, in which case the oil level should be checked with the oil dipstick in the future!!"
The sensor measures two things. Oil temperature for oil thermal load and oil level. If you let the housewife go fifty thousand kilometers by car, you have to accept that she does not even know how the hood goes up. Therefore, the sensor in the MFA only inserts the relevant saying. And cleverly this saying comes up again and again until the housewife finds out how the hood goes up
Like the battery or brake wear contacts. Everything just accessories to make everything reasonable.
Check the wiring, I also had a case that the rodent damaged these sensor wires.

Plug in place. And the message is removed similarly to the service inspection or already by obd on the computer? I'll check the entire length of the cable today.

Oh boy, that's a nasty topic. Go to block 17 instruments vcds and try to code this sensor. The sensor is connected to the clocks. It is checked with an oscilloscope. It should give two rectangular signals, one shorter than the other. When the light comes on, it's natural for you to go out and check the oil level. Then the computer sees that you are doing something and turns off the indicator at 100 km. Check the sensor in the mask.

The sensor gives a PWM signal to the counter. Check with an oscilloscope. Power and mass with a light bulb,

The only question is what will it give me that for 100 km it will turn off the indicator as it will be displayed again?

And tell me how to do it

This is not a monotonous PWM, but two signals superimposed on each other

And if it ever happens that my oil leaks, will the light not come on?

When the oil level is low, the red light starts blinking

Moderated By domex32:

Absolutely not, the orange light comes on. Red when there is no pressure.

Decide whether you want to have level monitoring or not. There is always pressure control anyway.

So you can turn it off and if it loses oil it will light up red?

No, once it lights up red, the pressure can be "after the birds" already. All kinds of sensors and other wonders do not relieve the driver from the so-called. oc, i.e. daily maintenance. Fluid levels need to be checked even during the exam it is.

Tomorrow, when I have a free channel, I will record the signal from the vw of this sensor on the oscilloscope and show you what it looks like. By the way, recode your clocks to English.

It should be, but not everyone does :)

Okay. How to change the clock language?

The sensor in the mask works, but after opening the hood, no information about it is displayed on the dashboard 0.o

Are other doors or tailgate displayed?

I don't know what the oscilloscope is all about. Yes, other doors are displayed and the sensor in the hatch has already been fixed and is also on.

These sensors are defective. Replacement is often indicated.

How do you not get it? You plug into the sensor and if you have such a signal, it's ok. It was a measurement at 70 degrees.

The new sensor is new. I am surprised that sometimes he does not display the oil sensor message

This is the first time I see something like this xD I don't have an oscilloscope

After checking with the computer, 2 errors keep popping up:
00562 - sensor for oil level/temperature (G266)
30-00- open or short to B+

18062 - please check DTC Memory of instrument
cluster P1654 - 35-10 - intermittent

How to understand this 30-00 and what does this second error mean?

The second one is not important. When the first disappears, so does the second. I advise you how to systemically remove this sensor error. Because it's a bane. Use an emulator, etc. You need to check with an oscilloscope, preferably at the clocks, whether it gives the signal I gave you. But if you get a chance to code it, do it because it's going to be annoying.

Then how to decode it?

Vcds you enter instruments 17 block and there you have coding. Hover over the highlighted numbers and write or give a photo of what it shows you.

Check the connection behind the air filter.

The counter says that the sensor is not getting power.

Where exactly is this connector, what does it look like

By the fender behind the left headlight, near the air catcher, such a larger cube.

No, the oil pressure indicator light does not mean that it is enough to add oil, but that you should pull over to a safe place and call a tow truck.

Sensor power supply (fuse) checked at least?

I check all fuses.
Who exactly is responsible for this sensor?

Underneath the battery? I can't locate

Plug in the channel and check with a meter if it gives voltage to it.
