Hello, I am new to the forum. My Kamiq's oil temperature reaches 140 C. I can't use it right now. The oil temperature is not unstable, it regularly starts from 50 and reaches 140 in 20 minutes. Does anyone know the solution? They suspected an oil level sensor failure, it does not show a failure at the moment.

 

1.0 TSI Engine , 40000km, DSG

Thanks

I don't know but if you subtract 50 from 140 you get 90.

So lets suppose your starting point is actually zero then 90 is OK right?

 

Lets hope there is something wrong with that sensor not starting at zero.

Actually, I meant it starts to show from 50. Unfortunately, it doesn't stop at 90C

It is a small engine chugging about a big car but that seems like it's getting a bit warm. Any other issues alongside? What is the service history? Has it got the right spec oil?

0-20w castrol edge oil and filter maintenance was done a week ago. P0196 gave the error code, I deleted it with the obd device. It does not show malfunctions at the moment, but it shows the oil temperature extremely high.

Like 99% of issues here just take it back to the dealer if it’s under 3 years old.

 

 

 

 

That code seems to relate to oil level sensor. Any chance it could be trying to do a regen for the gpf?

Unfortunately, warranty 2. It's full in the year, so I had an oil change somewhere else. The unauthorised service could not resolve this situation.

@Kamiqaze06  Welcome.

Useful if you said were you are and what sort of temperatures /weather.

United Arab Emirates being rather different from Ireland, sort of thing. 

 

The temp should be at --- before getting to near the indicated 50*oC then to the 92*oC and rising and when things are working right bring the oil back down lower. 

 

As an aside.

re GPF,s.  Clearing them is different from a DPF.

I have not encountered such a situation, it seems to be early for gpf renewal.

20 minutes of normal driving in normal conditions with a correct sump oil level will never heat the oil to 140°c even if the oil cooler is blocked or an oil stat etc prevents flow through it so you dont need to panic and I would not stop using the vehicle but its your choice.

 

The first 15 minutes (approx, depends on conditions) of running the oil cooler is acting as a heat exchanger to speed up the warm up of the cooling system.

 

If the oil were really at 140°c then the engine would stink when you opened the bonnet and water vapour would come out if you opened the oil filler cap or removed the dipstick.

 

One of my bike engined race cars that had inadequate oil cooling would reach 140°c at the end of a 20 minute endurance race but only on a tight short circuit like Lydden Hill, synthetic oil is fine at that temp but I ran bearings on a 12 hour race when it reached 170°c.

 

Why dont you just feel the outside of the sump? use a glove initially in case it is over 100°c.

The temperature of the area where I live is 25-30 C . As you said - starts with - - comes to 50 and continues to rise non-stop at 90.

How often should the gpf regen? Haven't seen it yet on my car but I've done less than 1000 miles.

Thank you. It seems logical. I will try and inform you. In this case, there is a high probability of oil level and temperature sensor degradation.

I think it will be 100000km/ 62000 miles later at the earliest

I have just under 52000 miles.

@Blue8793841  I would not concern yourself with GPF regens.

Those posting with issues were asking about High Idle Speeds and the car running on and them needing to use the brakes.

Covid years, lots of cold start short trip type of use. (Similar to what a DPF does not like.)

These have been 1.0 TSI,s.   Fabia Mk3 & Octavia Mk3 as far as i have ever read and responded to.

I dont know your engine but 110° would seem to be an optimum oil temperature, 90° is too low IMO, most engines on short to medium urban runs in anything but summer conditions would never actually reach the optimum temperature especially diesels.

Edited 15 July, 20241 yr by J.R.

92*oC as an indicated oil temperature is quite normal with a 1.0 TSI 3 Cylinder at speeds like around 50-60 mph even in ambient temps of the high 20,s.

Rising to over 110, and higher under load and at speed. 

 

The temperature indicated on the car is not exactly accurate.

Flat out in hot weather i would not expect an indicated 140*oC.   So something is wrong.    Is the Oil quantity enough?   

 

Checked at Normal Operating Temperature.  As in around 90*oC.

I'd suggest getting the oil temperature sensor tested ASAP - if that reading is correct, be aware that synthetic oil can start breaking down above 135 C. 

If you take it to your mot garage they have a probe to put down the dipstick to check temp 

Edited 16 July, 20241 yr by Blue8793841

I'm sure that reading isn't the true number. 

Would be interesting to use VCDS to view what oil temperature reading is at ambient temperature when engine isn't running. That might give a big clue about sensor defect or not.

I can ask when I go to the service. I can also look at it myself with the obd2 device

No point using the OBDII device, it will just parrot the lies that the sensor is telling the vehicle ECU.

It's implausible that it is correct after 20 minutes if driving.

Great idea! But they might not have the probe in the future, at my recent CT test the guy was running the engine waiting for the oil to get up to emissions test temperature, I remarked that he had not inserted the dipstick probe and he responded that he had plugged into the OBDII port and the test equipment was using the vehicles oil temp measurement.

 

He did have a back up though, presumably in case the oil sender gave an implausible reading, he got fed up with waiting for it to reach temp (I had forgotten to get it stinking hot before the test) ,whipped out a IR temp gun connected to the emissions tester and pointed it at the DRL to fool the machine 🤪
