Engine system service required 097

[iep]

My 2008 D5 XC70 has started displaying the 'Engine system service required' warning when starting and attempts to reset (via the trip button and start/stop button sequence) do not remove the warning but result in '097' being displayed on the dash.

I've done a bit of reading and it seems to be a bit of a classic D5 issue relating to overfilling the sump. I gather that 097 actually refers to an air sensor error (either air intake temp or O2 sensor, I'm not sure) but that this can be triggered by the car burning/recycling oil from the sump as a result of the level being too high.

This seems plausible as I did an oil change two weeks back and, though I was careful not to overfill the sump, it did end up sitting around 3/4 rather than the 2/3 recommended on the little sticker.

I've drawn some oil off and taken it for a spin but no joy so far. Hopefully it will reset in time but I've bought myself a cheapo OBDII code reader from ebay so I can use that if I have to.

Anyone else seen an issue like this one? I'm hoping not to have to replace any parts.

Also, as a cautionary note, if doing your own oil changes, it seems safer to put in about 1/2 way up the dip stick rather than risk being over the 2/3 mark.

Hi Just had the same problem with my V70 D5 . The garage I bought it from had it serviced with all the belts replaced It was fine when collected and during the 100 plus mile trip home . The next start up the " engine service required " message came up . I tried to reset with button several times but got the 097 code . The car was running perfectly so decided to check the oil level as I had read on a post that this can cause problems . It was filled to the top mark on the dipstick ! I drew off 1/2 a liter that took it to about half way between the top and bottom marks . I drove it for about 20 miles and the message stayed on so booked into volvo to get it checked . The the next couple of day driving added up to about 200 and the message turned off so cancelled trip to volvo. All lights and messages normal now . I don't know weather this is normal but it worked for me .
Give it time to reset itself as its better than spending £80 plus vat at main dealer for resetting.

Great advice, many thanks. Appreciate the post.

I've bought a cheap obdii reader/reset device from eBay so will try resetting if it doesn't sort itself in a couple of hundred miles. I've only done about 40 since reducing the oil level so it might need a few more miles yet.

Hi I did exactly the same thing , I think its an Amtel unit . I did the check for faults and it said "no fault" but the message was still there. As I had by then booked it into Volvo to sort I thought I would let get on with it but it cleared a day or so after so as said I cancelled the appointment with volvo. Its still running OK .

That makes sense. I'd read a couple of other posts where people commented on 'historical fault codes' where the fault has cleared but it just takes a while for the 'flag' to be reset on the system.

Either way, if I try the OBDII reader (Autel Maxiscan) and find there is no fault code then I can be more confident that there really is no underlying problem that requires dealership attention.

Thanks again for your posts. Really helpful.

Hi,
I have the same problem on my 2008 S80 D5. I topped up the oil levels a day or two before the message "Engine System Service Required" popped up and suspect I may have added too much.
How can I remove some oil, without going to the extreme of taking out the sump plug, catching all of the oil (in something) and then trying to get most of it back in via the oil filler cap ?

Hi I just been reading this thread about fault code 097, and the message engine system service required. I have a 2010 V70 2.0L desire. Not only have I got the message and fault code, my car goes into what I have discovered to be called ‘Limp Mode’.
We are currently on holiday in Scotland heading home on Saturday, I’m looking for advice as to what to do, I guess some reassurance that this is all normal and drawing off oil will sort it. I’ve checked my dipstick on it is a touch over max level.
I can clear the message and take it out of limp mode by pressing and holding the trip button till I hear a beep, then when I restart the car, everything is fine, unless I take my rpm count over 2500, sometimes it’s just 2000.
Thanks
Mark.

I just had the same problem: a garage put in too much engine oil, after 200km the message „engine service required 097“ popped up. Pumped some oil out. Then I could not reset the computer, but after approximately 500km the system reset itself, no more message now. It takes quite a long time until the message disappears but it will finally happen. It’s a Volvo V70, 2.4 litre Diesel D5 from 2007.

Turns out the problem was a split air hose. So the computer was getting a false reading. All this technology and it can’t tell you when it’s a simple split.
