Beep, red triangle and "fault" when driving through corner

This has happened three times now and every time I had been driving for over 45 minutes and it happened when going from one interstate to the next in a long bend. I think it has happened both when going left and right but not sure. Did not have this issue when driving through town, sharp corners, bumps, etc. Only on highway bends after driving for a longer time.

There is a beep sound, a red triangle on the dashboard and the radio display mentions (roughly translated): "There is a problem". All is there for max several seconds and then it's gone.

I have afterwards connected my ODBLink adapter but no faults were logged.

Does anybody know what this could be?

 

I made the assumption that I would have seen it sooner and in steeper corners as well so I did not check this. But makes sense to check, will do so as soon as it stops raining here...

 

Your capitals and exclamation marks made me check the oil before leaving right now for a two hour drive: EMPTY!!

The oil gauge stick thingy came out dry. There is no oil warning light on in my car and I have added some not too long ago. I'm shocked.

Thank you both, you may have saved my car.

Is it possible part of the damage was already done? How would I notice? There sometimes is a drop in power when I am pulling up but that can't be due to low oil levels can it?

 

When I posted yesterday I had to leave asap so I added 0.75 liters (0.18 gallons) that I had in my garage.

I just checked my level and it is still showing empty so something is wrong and I will add more and won't use the car until there is a good level showing.

Usually I am not this stupid, this was not a smart thing to do at all...

 

I have looked under my car and as far as I can tell there is or has been no leak.

This means I have been driving empty for quite some time and yesterday drove for two hours after adding the 0.7 liters.

I will add more oil until it shows on the dipstick. Is there anything I can do to establish what damage I may have already done and how this will affect the further lifetime of the engine?
