It seems an old problem may be back.

Those who previously owned a later Volvo D5 5 cylinder will remember the issue with rising oil levels owing to a DPF regeneration software issue.

I had my D4 V90 serviced last week and when I did my usual Monday morning checks today I noticed that the oil level in 'car status' was below 3/4 whereas it always used to sit just below maximum. A quick call to my dealer confirmed that they are experiencing issues again and have been advised by Volvo to reduce the oil by 0.5 ltr until a software fix arrives.

I imagine the price of oil service remains the same- so it's a win-win situation for Volvo - putting less oil prevents the overfill + every 5th car costs them nothing to fill

Hi Cassell I also use the same dealer as you and had exactly the same situation and discussion as you regarding my S90 after a service two weeks ago.
I live locally so was able to call in to discuss with the technician who also confirmed to me that following advice from Volvo they now do not fill to the mark on servicing. He also ran me off the printout showing the exact level of oil in the car. They did this without prior notice I was going to call in which reinforces my belief that this dealer is one of the best in the network.

Worth a look here as plenty of talk about the issue:

Interesting that Volvo's temporary solution is to allow space for the oil to be diluted. Not an ideal scenario in my view...

A software solution for a hardware problem?

Yes i agree with you, i used to have the same problem with my old XC70 D5
there were a few reasons for the problem on the older engines.
1 seals passing on the injectors and on the high pressure pump.
2 wear and tear on the injectors allowing diesel leak off going down into the engine and diluting the engine oil.
My car used to bring up a code 068 on the dash which was about 10k miles so time for an oil change.
But as you said what the hell will a software update do???

I had a quick scan of the thread which seems a re-run of the threads on the V70 section a few years ago. I really thought that when I got my V90 I had left the issue behind. Seemingly no such luck

:angry_smil e:
What I didn't understand when I had the 70 and still don't is that WHY THE HELL with all the warnings available, down to telling me to have a tea break, there isn't one to tell me that a regen is in progress. I want to know! Especially with 0-20 oil in the sump.

A now unhappy V90 owner.

One of the few things I liked about my VW, there was an Android app called 'VAG DPF'. With an OBDII dongle, you could get live data on the DPF, soot levels, temp and regen in progress. You'd also know how many miles done between regens and notice a big difference between city and motorway driving. There is certainly a gap in the market for someone to create a similar app for Volvo but I am not sure how practical this is, if only VIDA can get relevant information. Would be great if an app as such came to fruition.

I've said it before and will say it again (in the hope that maybe someone from Volvo is watching

), they should take the lead from the way the Adblue warnings work and do the same for a regen.

When it needs a regen you get to choose to do it on a run where you know you will be driving long enough to let it run its course. If you fail to elect to do the regen within a certain period of time then the system automatically runs the regen and then it is up to the driver whether to keep driving or to stop and risk the impact on the DPF / leakage into the oil.

This would be a software update, presumably, as ultimately all you are doing is taking a feed from the sensor that determines when to run a regen together with toggling when that regen actually occurs. I assume no hardware changes would be necessary to introduce this solution.

I accept this is adding further complexity to an already complex piece of kit, but it is no more than the added complexity of Adblue (if you dont do something - ie fill up the Ad Blue / run the regen - within the relevant mileage / time allowance then you suffer the consequence - which for Ad Blue is that you cant restart the engine, which is arguably harsher than simply risking an incomplete regen).

Just saying, again.
