Astra III H - Oil Level Warning Light On Despite Correct Level, Sensor Replacement & Solutions

Hello. I have a problem with the oil warning light. After driving a longer distance, the orange indicator light on the dashboard lights up. After stopping and turning off the engine, the light goes out for a moment and you continue driving normally. The oil level in the engine is certainly correct. Not long ago, the red light was on in the same situation. After stopping, it also went out and did not turn on again. The mechanic has replaced the sensor and the red LED is not on, but the warning light is almost always on for a longer route. Maybe someone had similar problems because it is starting to irritate me. I will be grateful for your help. greetings.

Machine? Maybe the chest is missing? Connect for good diagnostics.

The gearbox is manual. I didn't know there might be an oil sensor in the box.

Show exactly (photo) which light is on ...

Now I can't take pictures, I'm at work. While driving, the orange light at the bottom of the desktop with the oil icon lights up.

Hello
I have the same problem, the oil warning light comes on in two cases, the first is after a long drive, the second after a shorter drive but at high revs. The amount of oil in the engine is normal. Sadur_86 did you solve this problem? I am asking for advice on why this is done, because driving with something like this is irritating.
greetings

I also know such a case. 1.8 petrol engine. The light comes on when the oil is 0.4l below the max. which is still 0.6l to min. They probably made such a sensitive arrangement because Opel often like oil. The standard is probably 0.8l / 1000km, so a lot. As you write after a longer route with higher speed, the engine will eat a little oil and burn the lamp. It is similar at high speed.

Unfortunately, the problem persists. The mechanic himself does not know what to do with it. On Sunday, at a distance of 35 km, driving at a speed of 60-70 km / h, the indicator light came on twice. It only goes off when you remove the key. The light is on even when the oil level is at max. This is terribly irritating when driving.

I have max oil, and the indicator lights up in the above-mentioned cases only when I am driving with the air conditioning on. (apart from the fact that the air conditioning loads the engine, I do not know what may have to do with the oil level indicator). Is it possible to somehow adjust this sensor so that it is not so sensitive?

Hello
I had the same thing, the mechanic thought for a long time, searched the forums and found that the oil was only fit for replacement, so he did and the problem ended since then, Probably the oil was too thin.

It is usually not a float but a temperature or viscosity sensor. Either the sensor is damaged, or the oil is overheated, too low-viscous or worn.

Change the oil in the engine. I had the same thing on the 1.7cdti engine.

I don't think so. If there is no 7k, I should also replace it?

Hello
Astra Astra but what engine is it?
I had a similar problem when the radiator broke, I do not know about other engines but the 1.7CDTI does not have any temperature control !!!!!! it's worse than a toddler.
When the engine was overheating, this light was on for me, as a side effect there was no warm air in the supply.
If you turn on the ignition, do you see any codes in the place of the local counter that can be deleted?
If you see codes right after turning it on, write down and search on Google, it may bring you closer to solving the matter.

Hello. Srara theme, but refreshing.
It's the same for me. After the city, even during the biggest torture of the car, nothing ignites.
How do you go man on the route, no matter what speed or the highway, a lot of km / h whether the local road, so 80 km / h, always lights up after about 30 minutes of driving.
It doesn't matter what the oil is, it can be new oil after replacing 2,000 and it's the same.

My observation - the oil was flooded to the maximum was calm and then it started, so here the alarm level set too low comes into play, the system calls for an early preventive refill.
It is similar with the level of the coolant (message on a large color screen), it calls for topping up already when the liquid level is 3mm below the maximum, it will literally add not even 100ml, i.e. to the maximum, and it is ok. The system is too oversensitive.
Returning to the oil, the indicator says oil, so I drank it and I know that it will always be on fire on the road.

Hello
You have a different display, I have mono and I have no info on the level of the coolant or its temperature, I can obliterate the engine and I will not get any warning, I had a cooler in the spring, if it were not for the fact that I had a cold blow, I probably would not have noticed . This Opel model is idiotic, even the Toddler had a temperature control and nothing here

In Astra H you can check the engine temperature in the service mode of the display.
With the engine running and the radio on, hold the Settings button for a few seconds until you hear a characteristic beep. Then with the BT button you can go through the pages with the parameters on the display and there you have the liquid temperature.

I also have a problem with this control, someone has a ready solution. For 4 years it was not like that, now, after pouring fresh oil again, the indicator light turns on after about 20-30 minutes of driving. There is oil on the dipstick. Flooded as always with the same GM 5W30 dexos2 oil.
1.7 CTDI 110KM engine (after lifting gearbox 6)

Hello, same problem
Astra h 1.9 cdti
1.5 years after buying the car, no problems
Now I'm driving around the city for a month, nothing happens, I'll go on tour, I'll drive 30 km, and there is a yellow oil icon, there is oil on the dipstick.

I did not give up and solved my problem.
First we replaced the oil pressure sensor - it did nothing.
Then the removed bowl - cleaned, etc - did not give
I insisted even though my mechanic wouldn't hear of it - change that new oil again. Filter too.
Oil changed to exactly the same, but bought in another wholesaler - the problem disappeared and never came back.

What oil was it out of curiosity?

Both times it was original GM OPEL GM 5W30 DEXOS2 oil.
I used this oil before. It was changed to the same and then this error appeared.
And as I insisted, this new oil poured into the garbage and poured exactly the same - GM OPEL GM 5W30 DEXOS2
The difference is that it was bought from another wholesaler.
Each time poured from the original 5l cans, I think.

P.S. The mechanic is my friend and I trust him 100%.

How long have you been using this oil?
I don't think that is the solution.
I bought different oils from different sources and the problem was always the same.
The oil level had to be kept high.

I've never had this problem. Occurred once after an oil change and we couldn't get rid of it.
So I decided to change the oil again.
Normally, I change the oil every 1.5 years - this car is driven by my wife - and it is about 3-4 thousand km.
The faulty change where we basically drained the new oil and refilled it was done after about 2 months of fighting the light. At that time, maybe 1,000 km was done, because I especially started to drive this car and test it, constant trips to the mechanic, etc.
The problem never came back.

I do not know what to do. The next month I drove around the city about 10 to 15 km in the morning and the same in the evening, I drove to the city 40 km from mine without any problems, the yellow icon turned on after 15 km and on the way back after 25 km, I wrote to the mechanic, he immediately wrote back that the oil level sensor was damaged
