Engine Oil Temperature Sensor Location

[Jacobwilliamshort]

Could anyone provide the location of the Engine Oil Temperature Sensor (Part No. 04L919824C I think) for a Voltwagen Transporter (2022) 2.0 TDI 110ps T28 Highline BMT SWB PV?
I've discovered the sensor is faulty (through ODIS) and needs replacing.
Diagrams would be helpful.

The part number you have given is the fuel temperature sensor not the oil temperature sensor. Which one is actually reporting a fault?

Apologies, but thats what was listed on AutoDoc. Seems it can be used for multiple functions (correct me if Im wrong). On ODIS, the Oil Temperature Sensor is giving the fault.

 

[manfrotto]

The oil temperature sensor is part of the oil level sensor which is mounted into the bottom of the sump.
It needs the oil to be drained to change it. Might be worth checking the wiring for damage first in case, so you don't have to change the unit.

According to research my engine family is EA288 (being 2020-2023). Therefore, it no longer has the combined oil level sensor and oil temp sensor. The combined sensor was on the EA189 engine family, pre-2020. Please correct me if Im wrong. But I think the Oil Temp Sensor is separate in my case.
Many thanks for your time.

Voltwagen Transporter (2022) 2.0 TDI 110ps T28 Highline BMT SWB PV?

What's the exact engine code - as four different 81...84 kW engines were possible on Transporter T6.1

According to VW workshop manuals and wiring diagrams all Transporter diesel engines 2016-2024 have combined oil level and temperature sensor.

On ODIS, the Oil Temperature Sensor is giving the fault.

Care to share details please?

The engine code is the following: DNAB071502

If its the combined sensor thats a simple fix, nice and easy to access.

No fault codes, but i notices the engine oil temperature fluctuating rapidly from 90-->120-->70 within seconds.
Checked ODIS, live radiator outlet temp sensor is stable at 89.7c. Oil pressure nominal aswell.

i notices the engine oil temperature fluctuating rapidly from 90-->120-->70 within seconds.

Is that on dash display or only in diagnostics? Is it any different when engine is cold?

Checked ODIS

Is it a genuine one?

I have this now. I ordered new hella sensor from euro car parts and fitted it with new oil change. Same story. I have start stop error too. Snap on diagnostic tool is coming up with code P019700 Engine Oil Temperature Sensor Circuit Low. Any Ideas? Only thing left I can try really is order the VW/Audi spare direct from them...

P0197 00 Engine Oil Temp. Sensor - Signal too Low

Would be more than helpful to know van's model year and exact engine code - e.g. to advise which fuse to check.

What does your diagnostic tool show for oil temperature and oil level? Something very very low?
My guess it's simply a wiring issue.

Hi MMI, Thanks for your reply. I am working away now so don't have access to van. Its a 2020 150 HP Kombi. Reg - Y6 SHM

My Father checked through the fuses in engine compartment and said they were all ok, maybe the fuse is somewhere else. If you have any other ideas please let me know! Much appreciated. See attached box he checked.

It is more likely a wiring (chaffing) fault especially if it is intermittant.

Its always present now. Used to be intermittent but now present all the time, along with start stop fault. Even after clearing codes from diagnostic stool

Rodent damage?

Rodent damage?

Having the same issues now. Same engine (2023 110 hp TDI => DNAB). VW dealer says almost sure rodent damage (not covered by warranty )

So T6.1 then -

maybe the fuse is somewhere else.

Indeed - fuse box C - in the cabin - fuse SC40 (10 A).
Anyways, the fuse feeds also the following below so if any of them works then fuse is ok.

Mirror adjustment switch -E43-​

Headlight range control regulator -E102-​

Rear fresh air blower switch -E179-​

Centre switch module in dash panel -EX22-​

Oil level and oil temperature sender -G266-​

Pressure sender for refrigerant circuit -G805-​

Parking aid control unit -J446-​

Coolant shut-off valve relay -J541-​

What does ECU report for oil temperature and oil level?

 

[FWhite]

What does ECU report for oil temperature and oil level?

Just going by memory:
Oil level descending from 0.84% to 0.67% between the last two measuring intervals. A lot more than usual but not dramatic. Actual level about in the middle of the stick zone, after 10.000 km and 0.5l top up.

Temperature after 2 hours drive on the highway changing wildly every second between 64 and 95 degrees (as seen on the dashboard).

BTW regen is still happening as usual every about 300 Km, when sooth approaches 30. Means bad temperature read not yet affecting regen IMO. VW said drive it until you get a red EML symbol (first available appointment in 6/7 weeks, still unconfirmed).

Had this on my 2023 110 DNAB oil temperature on dash charging from about 65 to 102 with in seconds. VW changed the oil temperature sensor which fixed the problem under warranty.

Sorry, meant actual raw data extracted with diagnostic tool via OBD-socket - as the dash displays are heavily filtered. Just engine off.

Oil level descending from 0.84% to 0.67% between the last two measuring intervals.

Not sure where those values come from, perhaps some of the compensated/proportional values - the raw oil level from the sensor is millimetres.
