The low oil level warning came on today.
I stopped the car, checked the oil level with the dipstick. yes, definitely low. I added oil. Now about halfway up the dipstick check area.
However, I don't know how to turn the warning condition off. There are no options to reset it (as there are for low tyre pressure).
The manual says that the warning goes out when the bonnet is opened for more than 30s, and comes on again after another 100km if the oil is still too low, but this is clearly incorrect - like much that I find in the manual! I had the bonnet open for several minutes while I topped up the oil and re-checked it.

Is there a way to reset the warning that doesn't involve paying a garage to do it with diagnostic gear?

The car is due for its oil change anyway in a couple of weeks, so maybe I should just live with it until that's done. . .

It is correct that the warning Yellow Oil Can light or message will go out if the bonnet is opened and even no oil added, and will stay out for 62 miles / 100km. So you have a fault somewhere. As to your half up the cross hatch, how much oil was that you put in? Still too low really. When was it last at a good level, miles ago, or weeks?

I probably do have some electrical faults with this car. The stop/start has a mind of its own, for example. Sometimes it works, sometimes it doesn't.
No idea about what the oil level was like before. It has got low before though, so there's a slow leak. Last year I took it to a garage to find and fix it, but they couldn't find the leak.

So I suppose this means there's no way to clear the warning light.

Intermittent stop/start is usually an indication of battery low state of charge - either from low use, or failing battery.

Try adding more oil to bring the level fully to the top of the indicator line on the stick - it's possible that there's a hysteresis in the switch between warning off/on.

It's a really poor idea to rely on 'idiot lights' when it comes to maintaining vital fluid levels in a machine that can destroy itself very rapidly if they are not there.

This behaviour started following a routine service it had a few years ago. Stop/start suddenly stopped working altogether after the service. At the time I thought the garage had just found some way to disable the stop/start, maybe for testing and had forgotten to turn it back on again. As I didn't like the stop/start anyway, I didn't ask the garage what they'd done. After a few months it started working again intermittently. It seemed to be obeying "Sod's Law": sometimes turning the engine off when I was stopped at traffic lights for a few seconds but not turning it off when I was stuck in gridlock traffic or major roadworks for several minutes. I think I had a new battery fitted at about that time (by another garage), so the current battery is not that old. I need to find my old receipts and check this. . .

For intermittent stop/start operation it is possible that the replacement battery wasn't adapted into the vehicles BCM correctly - or the battery is faulty.

Have you checked charging voltage at the battery terminals?

Battery needs to be coded into the cars electrics or the car will charge it as if it was an old battery, so the new battery never reaches its potential, so to speak.

Sorry cross post Warrior1963
