I have a 2013 S60 T5 FWD. Every once in a while when I brake to go over a speed bump the oil pressure warning light will briefly flash.
I recently changed the oil and have verified the oil level is correct and accurate. I check my oil levels at least once a week and the level isn't dropping between oil changes. I have not been able to find any evidence of a leak.
Some searches online show that the oil sender might need to be replaced or that the wiring to the oil sender might be bad.
I was hoping someone here might be able to confirm the info I found regarding the oil sender or might have some other suggestions. I appreciate any help on this.

 

Its possible that the oil sensor or wiring is at fault but you may also want to have a shop do some run time monitoring during a test drive just to make sure its not related to debris in the pick up or a general low pressure (ie lower than normal) condition. Has there been any recent work or event that would have possibly compromised thie wiring?

 

I did recently have the fuel pump replaced, and an engine mount replaced. Other than that just regular maintenance that I perform myself.

I appreciate your feedback!

 

How many miles, how often is the oil changed and with what kind of oil? Synthetic, semi- synthetic, or just regular oil?

 

69,000 miles, full synthetic, I change the oil every 5,000 miles.
