All Diesel engines fitted with a dpf system have an oil quality sensor in the sump . Perhaps it’s faulty or needs cleaning?

Really? Hadn't heard that. How do they work?
For diesel dilution you'd probably want to measure viscosity, which aint trivial.
I used to be a bit interested in oil quality monitoring, and briefly fiddled around with scanning digital photos of paper chromatograms (look up "blotter spot test") with the idea of running a student project on it, but couldn't fit it into the schedule.
Got a nice graph though
That MIGHT detect diesel fuel dilution, but I havn't tried it for that
Quick search turns up this

This is a viscometer. Spiel is tediously repetitive but focus seems to be industrial process control. There's no mention of it being applied in cars.
and this
www.descase.com/products/condition-monitoring/sens.../
Works on dielectric constant, apparently. Rather hard to believe it can be very specific in monitoring "all wear, all contaminants and oxidation" so it probably just outputs a go/no go number. Viscosity, isn't mentioned.
There was a DIY-targetted hand held gizmo (Lubricheck?) that IIRC allegedly also worked on dielectric constant, but that seems to have disappeared.
Amazon now has these rather dubious offerings

Didn't find any mention of OEM sensors, though someone must be selling them

Great Post!
Really informative.
I agree, never heard of this sensor in my life.
What usually flags up is 'Oil Level Too High' (because of waste Diesel in the sump).

Could be full on that milage. They can be cleaned out.
They are very expensive to renew.
I suggest you have the fault codes read first, before throwing parts and money at it!
Good Luck with it.

After code read, there is only this code, related with oil deterioration.
Where is this sensor located ? Is it integrated to oil level sensor. I tried to find oil quality sensor for my motor but no luck. I wonder also if DPF regen fails should it throw some error code ?

At that mileage, I suspect your DPF may be full. You can either replace it (expensive), have it cleaned (perhaps not worthwhile), or delete it. I suspect from your post, you're not UK based and don't know what the rules are where you are.

How come the Mary Whitehouse Module removes leading caps from naughty words? Are they somehow more offensive when correctly punctuated?
Surely it should be the other way around, if anything?
I tried both b******* and b******s and it happened both times

Thank you all. Correct guess, I am not from UK, but the regulations here are same I guess. I can't cut out the DPF.... anyway the question of oil quality sensor used in cars still remains.

Most cars where the marketing dept proclaim an "oil quality sensor" actually just use an algorithm in the ECU based on mileage and number of cold starts.
Some cars have multiple oil change counters, eg minor and major - with owners able to reset the minor counter but needing full diagnostics to reset the major counter.

Because Little Boys like yourself, can't be trusted on a Keyboard, without Mummy watching over you.
Learn some words instead of swearing. It makes you look stupid!
Google and You Tube are only tools.
If you can't use tools it's your problem.
Perhaps if you went away and let the Big Boys help this chap?
Your clearly out of your depth.
This code is generated after 'X' amount of failed regenerations. It's software based and is a counter system.
No Sensor.

But then if I had gone away, you Big Boys wouldn't have had the benefit, if such it was, of that "Great Post" you enthuse about above.
(Unless that was "I very much feel your science is very useful to me" stylee sarcasm". a tough act to follow)
I know Mary doesn't like swearing (though I don't think b******* IS actually swearing) Thats what she's for. I was just puzzled by her dislike of correctly capitalised swearing. A minor technical algorithmic issue, IOW
Still, I suppose none of us can guarantee consistent consistency.
Seems we agree that an on board oil quality monitor (as opposed to a usage based estimator algorithm) is a bit unlikely,, at any rate

Mary died over 20 years ago.
The UK is quite a different place now.
This site is visited by kids, including my own Grandkids.
Why the need to use any kind of Swearwords.
Save them for the Pub.
(swearing only sounds good, coming from very well spoken ladies)!
Your post was interesting,taking away viscosity and temperature, however for what seems an educated person, looking at your previous posts , your engineering skills leave a lot to be desired!
I would listen to you, but I wouldn't employ you.
Have a great day, as they say.

Engine oil level sensors, OTOH, do seem to be a thing

according to Librewolf browser, that is. Havn't tried Google...

Mods don't have any control over the swear filter apart from being able to add words. We can't take them out. It is what it is, warts and all including the noted capitalisation which is news to us.
Good to hear that there are youngsters reading the forums. There was me thinking it was only argumentative adults ;-)

Must admit I found this a bit surprising, even disturbing. Why are the poor wee things spending time here, in this domain of Oily Old Men?
(Girl I knew in The Yook used to refer to me as an OA, which I gather stands for Oily Anachronism, though uncomfortably close to OAP. Sarky Cow)
Shouldn't they be running in the sun, flying kites, collecting shells on the beach?
Then it dawned on me that if I had grandchildren they might now be coming up with 10-year-old-Corsa issues.
Sobering thought.

I saw your previous posts, including your "no sensor" post, where you say its based on the regen history.
As above, it seems that at least some Mondeo have an oil level sensor, (though out of stock with that supplier)
Dunno how they work but from the picture its got a heat sink on the body, so maybe microwave level sensing, with a microprocessor.
I took your "no sensor" to mean it hasn't got a sensor, but I suppose its quite likely to issue a warning based on regen monitoring AND/OR oil level sensing.
If it has an oil level sensor I would suggest the OP doesn't assume its at fault, and be persuaded to replace it, parts cannon stylee, since, as suggested above, its quite likely that DPF regens are causing oil dilution and a rising oil level.
Apparently Ford advocate not filling to the max to allow some headroom for this, a rather off-putting work-around.
www.talkford.com/threads/mondeo-2-0-tdci-140-oil-c.../
Hopefully, presence of an oil level sensor, if it has one, doesn't mean you no longer have a dipstick, and you will still be able to directly monitor your oil level.
Seems there can also be issues with dealerships failing to reset the OLM after an oil change

Micky, if you aspire to a role as Moderator, why don't you do it officially ?
Reverting to topic, and thinking as no more than an interested amateur, we seem to have established that the OP's car is accumulating fuel in its sump. Which suggests that the problem may lie with regens - which then suggests that the DPF may be time-expired because of the high mileage. To me, that seems a simple explanation, but I'm probably wrong ?

We havn't "established" anything.
Dead DPF is one possible (and likely) explanation.
The OP seems to like the idea that he's got a faulty oil monitoring gizmo, which would probably be cheaper than a DPF, so an understandable preference.
Direct physical monitoring of oil level, with an Olde Worlde dipstick, could give some unambiguous diagnostic information.
Without a dipstick, one is a bit screwed (which Mary doesn't mind. I established that earlier)

It seems a good explanation, however the Parts Cannon is an expensive gun!
Simple code read, should give enough facts for a correct fix.
Could be the DPF, or the oil level sensor. I'm sure a car of this age will have a dipstick, so that's an easy check. My Audi doesn't have one, but one is available to buy??? So perhaps even borrow one.
Lots of folk just have the DPF removed and mapped out. Half the price of a new unit!
Me a mod? Tounge in cheek surely?
Sorry, I don't have time for the real world, never mind the pretend World!
Too many Rocket Scientists and Keyboard Hard Men for me to deal with.
I use these forums for help and to occasionally share my past fixes.
