No it’s not. They are dry sump in many instances.

It is a Volvo franchise you work in isn’t it?

Sorry , I didn't mean or say a Ferrari has an oil level gauge i mean it is specialised in all ways just like most cars including volvo these days so you need to know the ins and outs of them and exactly how things work before you do anything to them , which includes topping up the oil

I'm not against electronic dipstick systems, in fact most of us are happy to be reliant upon the fuel gauge. It's just that this engine oil level system used by Volvo does NOT present an accurate indication of the oil level, despite the sensor element having an apparent sensitivity of 1%... it seems to have been dumbed down to avoid the need for any operator interpretation, merely giving a 'min' or 'max' indication as a threshold is crossed.

And why must it be reset at every oil change? If the sump is fully drained, then refilled with the correct volume of fresh oil each time then surely the sensing system must give the correct level indication? Unless it drifts over time, it which case it seems wrong to claim a 1% accuracy?

It's almost like Volvo would prefer owners to just take the car to their nearest dealer whenever a warning message is given...

Because it then takes what ever level is in the sump after the oil change to be the correct 100% level ... hence calibration .. There is a tolerance of how much can go in , over the last 5 years i have found 5 litres is the correct volume to fill with , that is half way in between the allowed tolerance ... Yes i have said earlier , if you change your own oil and put exactly the same amount in each time it will always be calibrated ok . No it doesn't drift . it remembers the level ( which is assumed to be correct ) At the point of calibration .
The level gauge is good if used properly , it informs 100% of owners whether the level is high or low and advises the correct quantity to top up with . In my experience , probably 80% or more of people would never check oil levels , just the same as they don't check tyre pressures hence those being a legal requirement now !
This may be a bias place to talk about that as 100% of us always dip our oil and check tyre pressures weekly ..

I am absolutely against it 100%. Manually a dipstick is a tube with a rod pushed in. How does it fail? How do you misread it? Putting electrical sensors in and having them calibrated is absurd. I would go as far as to say I wouldn’t want a vehicle with that set up.

The roar of 'Hear Hear' is heard throughout the land of Volvo and beyond!
Why replace the blindingly simple, cheap and obvious for a temperamental and needy electronic widget! I also suspect those that are unlikely to check a conventional dipstick would also be unlikely to go through the rigmarole of checking the electronic one.

They don't have to check it , that is the whole point , It will warn you with a red or amber light and a message if attention is needed which suits the masses just fine ...

I see, in the same way that a dipstick and rod also have a low warning light.

It is a rubbish system devoid of any Benefit.

.......who then process to the main dealer for an oil top up. I wonder what Volvo charge for that!

Your faith in the Volvo electronic system is reassuring and whilst arguably sophisticated it may be technically, I and many always saw the oil warning light as the backup to the dipstick. What I wonder was Volvo's motivation for dispensing with it.

you can top it up yourself , it tells you how much to put in .. The only trouble encountered with these gauges in my experience is when they have been neglected by the person who is doing the oil change by not following the correct procedure .. . The vast majority have no problems the ones that do seem to congregate here which gives a false impression of real world reliability.
With the old dipstick system by the time the oil PRESSURE ( not level) light came on it was very close to too late .
