Oil overfill warning??!!??

I’ve said it before but I’ll say it again anyway, garages really should not refill engines to the Max mark on the dipstick, including a virtual dipstick. Halfway between the ‘fill’ and ‘max’ mark should be the aim and some dipsticks do indeed have three marks, ‘fill’ ‘full’ and ‘max’. Engines with in-sump balancer shafts may need very little volume of extra oil to go from fill to max and beyond. Some may have very little leeway between ‘max’ and the crankshaft journals hitting the sump contents and causing the oil to foam with potential consequences.
Do not overfill or allow dilution to overfill during use.

Well, I've now done several journeys over 30 miles and still I just see a single line marker for the oil level indication... Really not a problem, just odd that it should have changed.

As my oil level is still showing in several lines and yours a single line I guess one of us has something unusual.

When you check the level do you just press the status when travelling or do you stop the car on a level after a good run, wait say 5 mins and then turn and hold the start button for approx. 5 secs and then read the status on the screen?

n my case , 2017 V90 D4 no Adblue, it doesn't seem to make a difference. I always get one vertical line with the scale reading from left (low) to right ( high). There was no difference after having some oil sucked out and the software reset.

I only ever check the level when stopped and after a run, when the engine is hot. I've not changed the way I check...

It sounds like my display is now the same as Boatie.

As long as I can check it and the display is reasonably accurate, I don't care too much.

I think the solid blue bar looked better though, haha.

So it looks like my several lines from left to right and not a single line indicating the oil level is the odd one out. Must say I like the look of the several lines that build up to the indicated level over the single line I had just prior to the service. Agree though that the solid blue line looked the best!!.

My level is still below max so looks like it’s not as bad as I thought.

Having come from a Discovery Sport oil dilution is a well documented issue. What I have not seen mentioned in this thread (apologies if I missed it) is the impact upon lubrication properties as the oil gradually becomes diluted.
My XC60 has been showing oil overfilled for a few weeks, dealer unable to look at it until yesterday. They checked the level, confirmed it was overfilled but not excessively. Drained out a small amount, according to dealership all now ok. However I am taking this further with Volvo. below you will find the details of the email sent, including % dilutions before the user gets any indication of diesel dilution.
I will post an update when I get a reply from Volvo UK.

I am writing to you today in relation to an oil dilution issue I am experiencing with my Volvo XC 60 Inscription Pro D5 2019. Reg XXX.
I first noticed this in November when I noticed the oil overfilled warning had illuminated on the Sensus screen. Lipscombe XXX checked the vehicle but could not replicate the fault. 24 hours later the overfilled warning re appeared. I booked the car back in for today, the earliest booking.

The work undertaken today was to drain the excess quantity of oil, not replace. I understand that the Volvo remedy for the oil overfilled message is to refill to 4.8 not 5.2 litres of oil, ie a minimum of 400ml of capacity for diesel. You will be fully aware that Diesel is not a lubricant, as such testing has identified that levels above 5% start to reduce the lubrication properties of the engine oil.
I do not know the set point of the oil overfilled, or service required sensors, but have taken an educated guess of 200ml above 5.2 litres.
For the revised oil fill levels this would give a potential diesel dilution figure of 8.3% to reach the original oil level, or 12.5% if the oil overfilled level is at 200ml above maximum.
In my case I am assuming 200ml of diesel on oil .2/5.2 which is 3.8% (not desirable but acceptable).
Assuming that my oil has been drained to 4.8 litres than the oil overfilled will initiate at 16.3% far to high, as this level of dilution will result in internal wear.

My plan is to keep this vehicle in excess of 5 years 80,000 miles. As such I am getting increasingly concerned re the long term reliability of the engine, should diesel dilution of the lubricating oil continue.

I would like the following information in relation to Volvo’s experience of engine oil dilution due to diesel, caused during DPF active regeneration.

What is the maximum % of oil dilution Volvo deem acceptable.
What experience has been gained at these dilution levels in respect to wear metal analysis.
Does the loss of lubrication impact upon long term reliability of the engine.

For my vehicle specifically, is it acceptable for oil dilution to potentially exceed 12.5% ?. Should the oil & filter have been changed during the latest dealership visit.

In respect of warrantee as already stated I am getting increasingly concerned re the long term reliability, as Volvo willing to extend the manufacturers warrantee from 3 to 5 years should the diesel in oil issue not be resolved.

I look forward to hearing back from you in relation to the points I have raised.

My MY18.5 XC90 D5 had just a singe bar to show engine oil level when new in Mar 18. It was serviced in Mar 19 and still oil level shown by a single bar (and I check it regularly).
Car went in last month and had the latest software updates applied and the oil level is now displayed as a bar graph (oil was not changed/altered in any way) so I think the new display format is possibly as a result of the Nov 19 Update.
My car has always shown just a touch under the ‘full’ level on the single line notifier and now shows in exactly the same place on the new ‘graph’ and I feel the graph is a better representation of oil level.

I had my V90 D4 at the garage for the oil service level erro, whilst speaking to the tech I mentioned that this seems to be a common problem, he replied that they had quite a few in for this issue.

He said that basically they would change the oil and filter but refill with half a litre less than normal. They also said that they would update the software to the latest available.

When I picked up the car they had basically given it a mini service checked everything but that my front tyres were on the legal limit. The car only has 15,175 on the clock so not sure if that is about right for the car on not

Overall regarding the software update they have changed the graph for the oil level and changing gear seems a lot smoother especially going from 1st to 2nd.
