Engine oil level?

On the 2019 Scania 450s that came no dip stick, had to check the oil from the dashboard by going into the computer, most of us do not like it, much prefer the dip stick.
 
One of my shooting chums bought a nice Audi estate diesel and just found out it is dipstick-free. He's uncomfortable with that and will probably move the car on.

It's not oil pressure, that sensor and indicator works, just as you describe, all the cars I've had the light only goes out once the engine is running as until that point there is no oil pressure.
This is a different sensor, it checks the actual presence of liquid oil in the sump. Trying to reset this via the usual port is not successful as every time the start up sequence is initiated, it happens again.

Have you tried a system diagnostic with an OBD2 scanner? If not, you can pick one up off Amazon for under £30. You can scan for error codes, it will find them and you can reset and delete them.

I’ve done this a few times over the years and the thing has saved me a fortune in repairs on BMW, Merc and Ford.

Something like this…

Yep electronic dipsticks are stooooopid. My 2016 XC60 had no physical dipstick when I got it but turns out you can buy the parts and install it so I did.

I like to see the colour of the oil as well the level.

My Honda has a sensor in the sump that outputs to the control system and an indicator light on the dash. If the sensor detects no oil in the sump, it lights up the warning indicator. So I pull the bonnet catch, get out of the car, walk round the front, lift the bonnet, check the dipstick and hey presto, there is oil on the stick and it's midway between the high and low marks.

I get back into the driving seat, press the button to acknowledge the fault, then turn the key, and the engine starts and runs perfectly.

After having been caught by this on several occasions I now short cut the process, just ignore the warning and turn the key.

I find it hard to imagine how the start up procedure having checked for no oil still allows you to turn the key and start the engine. Surely if there really was no oil, the system ought to prevent that.

The sensor on the sump base is not a pressure sensor . It's there to monitor the oil service intervals and needs to be reset at oil changes.
It will check that there is oil in the sump obviously and is mainly used for long life services.

Colour is a great indicator of something going wrong. Electric level check is plain stupid…

If that is the case, it can definitely be reset with an OBD2 scanner. That is all the main dealer would do.

Knew a man who bought a new Merc. At 10K he notice a noise and asked me what it might be.
Idling on a level driveway , it could be heard sucking.
I asked when he had last checked the oil. He said service wasn't due until 25K.
No oil showing on dip stick, so purchased oil and topped up. No more sucking noise.
Extremely lucky because next day he was doing a 600 mile round trip.
Doubt Merc. would have replaced engine under warranty..
A new engine can be as greedy on oil as an old one.
This is also true of small 4 stroke engines found on lawn mowers. mixers and generators.

I tell thee now.
I haven't checked my oil level since 1995 on any car I've had and always been OK so will continue to do so, mine only needs changing at service time.

Thank you 😊

Not correct attitude, what if you went over a speed bump and ripped some of your sump pan,without you knowing :)

At least I don't have to pay the garage for an oil change and I just top it up every morning before I leave for work ..

When the DPF regenerates it can cause diesel to get past the pistons and dilute the oil as it over fuels the engine to heat up the DPF.
If the oil is already near overfilled it won't regenerate.

I never new that! I always keep my connect on the top... maybe I should syphon some out 🤔
 
For it to regenerate it needs all the glow plugs working,the Aircon to work and as mentioned the oil level to be under filled slightly.

My Honda will not allow my Topdon 600s to do it .
Honda are funny like that.

I’ve got an Autel Maxicom that can read anything but that was bought because my wife and two daughters all have different cars. Between the four of us, we have Merc, Ford, Lexus and BMW! 😂😂😂

Unless I chucked some money at one, I might have ended up buying four. 😂

The Topdon has the facility but computer says no.
I also have a Vagcom, a Launch and a specific Land rover Pscan.
Saves money to buy your own.

Yes it is good to see the colour and by checking regularly on a dip stick you can see if it goes down, hard to tell with the display.
I think there is a dip stick under the cab on the lorry but it would have to be tipped over, it’s so stupid not having one.
