I have a Volkswagen Golf MK4 TDI 85kw (AJM). After driving for a while and stopping, when I turn the ignition on I get an "Oil sensor workshop" message. After connecting VCDS I got this fault:
00534 - Engine Oil Temperature Sensor (G8)
27-00 - Implausible Signal
As far as I know its the same sensor for the oil level too. I've done some research and I found that these sensors can be disabled. On some forums, I found that you need to re-code the instrument cluster module and set it to 17402 or 17432 but neither of these works for me. The first one is just an invalid option and the second one was coded with no success. I'm wondering if there are any other ways of doing that? Or perhaps I did something wrong?
Also it would be nice to hear what are the possible causes of getting this exact fault as it appears only when the car is driven for a while and the engine is hot.
*Note: I used VCDS-lite registered version for connecting to my car.
I've tried to disconnect the connector from the sensor. I actually expected it to show me "Oil sensor workshop" message all the time but at the beginning it looked like everything is fine no message on the dash. And after driving for a while the fault appeared as with the connector plugged in.
Detailed information needed about theese questions
Is there any way of programming out this sensor?
Is there any way of fooling a computer about this sensor using resistors or something like that and how?
As there are 3 wires coming to that sensor, how does it work? what's the purpose of each wire, and if data used by the computer is the resistance of of specific sensor's connections whats the normal resistance between each of them?
Is this sensor used to only warn a driver about the issues with the oil level or temperature or is it that this data also used by the main computer and does it affects how the engine runs? What exactly is affected by it?
