[Solved] Octavia 5E 2.0tdi - 5580 -Oil Pressure Switch help in locating the sensor.

Hello

Gentlemen and Ladies, I am asking for help in locating the oil pressure sensor / switch in Octavia 2015 2.0 Tdi CRMB.

The error occurs sporadically, but more and more often, the glow plug light flashes and the car starts to slow down. Usually and most often on a cold engine. Usually, after warming up, just turn off the engine and start it again and you can drive without any problems.

Does anyone know or have any illustrative drawings where this sensor is located and from which side it will be better accessible?

Preferably, from the bottom, near the starter, you have 2 sensors, brown and green, marked in diagram S2

Thanks for fast reaction.
I have Etka 8.1, unfortunately an attempt to generate a file with the TMBKJ7NE7G0084850 wine myself resulted in the message "unknown sale type" from Etka. I looked through all the drawings that could be related to my engine or electrics, but I did not find any photos with these sensors.
But I googled that it`s most likely these?
04L 919 081 and 04L 919 081 A


Replace both as a preventive measure, or do these errors and symptoms suggest any particular one?
Could I please ask for part number A54 "Oil Pressure Regulating Valve".

And the sensor cables are ok?

You provided the correct original number, due to the location of these sensors, replace two.

Does my engine have part A54 "Oil Pressure Control Valve"? If so, what is the number, if I may ask?

The reason for the P164B00 error is a faulty F1 brown oil pressure sensor no. corrected code 04L919081B . The second one (looking at the engine on the right) is the reduced pressure sensor. There is a pressure regulation valve in this engine, but there were no problems with it, but the issue of the sensor was known in the group.

Sensors replaced with: green original and brown Febi 107974, first day approx.
I will wait a few more days and if there are no more problems, I will close the issue.

For now, I would like to thank everyone once again for their input and help in fixing the error.

Ps: Does anyone know where I can ask for a wine bag for Etka? TMBKJ7NE7G0084850

Hello, let me add to the topic.
Golf 1.6 TDI data from 2015. and error code P164B00, the same symptoms - emergency mode during sudden acceleration with the engine not warmed up.
Today I was at the dealership for inspection and diagnostics, a very nice gentleman said that they would have to disassemble the engine and look for the cause, and I would have to leave the car for 2 days. A man-hour of PLN 320 x 2 days = a bag of money.
The solution to this issue shows a faulty brown sensor, but there is something that really bothers me - in my case, the problem started after changing the oil to Castrol. A friendly Bosch service tells me to start by replacing the oil with a higher quality one. The car has traveled 2,000 km since the replacement, I don`t want to believe that it could "not like the taste of the oil". Maybe it`s a coincidence?

Replace sensors. After the replacement, i.e. about a year ago, I forgot that such a problem even existed.
And by the way, it`s a nice ASO.

Added after 2 [minutes]:

Replacing the sensors solved the problem, but I don`t know which of the two caused the problem.

The topic was unlocked at the author`s request.

I replaced the brown sensor - 04L919081B, problem solved, the car runs as before. When it comes to replacement, in the Golf VII, just remove the covers on the front fascia and access the long 24mm socket from the top, no need for a workshop.
