I say interesting because you described it only happening during low speed driving. I was just letting my daughter practice in a store parking lot for about 5 - 10 minutes. Then I drove the 1 mile back to my house, as I was pulling into the garage I saw the message.
Same as you, there is no leaking and the oil level is fine. I'm between 4 & 5K miles on this oil change.
I'm wondering if it's just something about driving low speeds.
apparently it happens at low speeds when there's not enough pressure.
After reading some more people say first steps you should take is check the oil level(obviously) and after getting the engine at running temperature pull the dipstick and check for air bubbles in the oil on it.
if that happens it could be a worn gasket or a seal and the system is sucking air in. that's not gonna be cheap apparently, the kit is cheap but there is some labor involved, about 3.5 hours to remove oil pan, clean etc..
just checked for bubbles this morning and looks like that's my problem so i'll take it to volvo for a diagnostic check, they'll probably have to change the above and hurt my pocket but i hear it could go really bad really fast and i don't need a blown engine. seems to be a common issue(more or less)
the easiest would be a fauly sensor but from my searches it's usually not that.
still you can take it to fit a manual gauge which will check the oil pressure at different rpm's and that will tell you if it's the oil pressure sensor or not.
the worst case scenario would be the oil pump(part is kind of expensive) but i hear those rarely go, volvo shops say they only changed a few of those over the years.
either way it's gonna cost me and suggest you check for air bubbles too and take action before it gets worst that's probably gonna be the issue anyway.
