Default D5 oil rising & leak - Engine System Service Required

Hi Everyone,

I recently privately bought a 2009 XC90 D5, 109k on the clock.

A few issues have developed since my purchase, which I would love to get your help on.

First thing was that going up a hill with my foot down, i got a message appear ''Engine System Service Required''.

This lead me to do some research, which pointed towards the swirl arm (shocking piece of design!), which i have checked is intact.

The next 'quick fix' i found doing research was the oil level, as I understand it this should be 3/4 max on these EU4 engines. So I checked this today, and the level is well above the maximum, by at least 1cm. So I am draining the oil down to the correct level as we speak.

This has me wondering what is likely to have caused this? I'm going to be getting the VIDA codes read by a fellow member on Thursday, i'm hoping this might shine some light on this. I've read various things could be at fault including EGR, Swirl flaps, Injectors, and Blocked/failed to regen DPF.

I'd like to keep my costs down as much as possible and try and tackle as much of the diagnosis myself as possible too, so your input would be greatly appreciated.

On a similar note, when i had the engine cover off again, I noticed some oil spray around a pipe here, has anyone seen that before?



Thanks
Jack

Firstly, use engine cleaner on the area to clean off all the muck so you can confirm where the leak comes from

I looks like the metal pipe to rubber pipe junction at the PCV valve.

Remove and clean and refit the PCV valve.
You may need to replace it.

As for the engine system service required, that can be one or more of hundreds of possible issues.
Only way to tell is use VIDA and read the codes.
Then go from there.

Hi bud I seem to have the exact same problem with my 56plate V50 diesel sport 😫. I go up a hill and my engine system service light comes on and goes into limp mode. Did you manage to find the problem? Many thanks

Sorry for the mega long reply!!!

It was the oil level being too high!!!!

The dipstick has incorrect markings on this car resulting in overfill. Really shoddy from Volvo but taking 0.5 L out cured the problem.

Hope this helps.

It is fuel dilution from dpf regens which raises the level, and yes overfull causes this message!
I doubt dipstick is wrong, they use the same dipstick as original to the D5 at inception, but had to reduce fill volume because of this very issue, hence a 'fill' is to 3/4 whilst max is still max volumetrically, once level goes beyond this it will flag-up.
