C8 Oil Pressure Warning Light

I've got a 2011 Citroen C8 diesel. A warning light came on in the speedometer, and the oil pressure warning lamp is lit. Could this be from exceeding the maintenance interval, maybe causing oil contamination? Has anyone else seen this, and how did you figure out what was causing it?

The conversation centers around a 2011 Citroen C8 diesel with an oil pressure warning light issue. The initial concern was whether exceeding the maintenance interval could have led to oil contamination. A similar experience was shared, suggesting checking the oil for sludge or discoloration. The problem was confirmed to be oil contamination due to delayed maintenance, and it was resolved with an oil change and filter replacement.

Did this summary help you solve your problem?

I had something similar happen with my C8, though I can't remember the year. I ignored the light at first, thinking it was a sensor glitch, but it kept coming back. Does the oil look sludgy or darker than usual when you check the dipstick? Have you tried any oil additives, or checked the oil pressure yourself?

Thanks. I'll check the oil more closely for sludge or discoloration. I haven't tried any oil additives or checked the oil pressure directly. What additive did you use, and how did you check the oil pressure?

I wasn't really recommending any additive, just wondering if you'd already tried something. Honestly, seeing the light kept coming on, and not knowing much about engines myself, I just took it to a workshop. It turned out the oil was indeed contaminated, as they suspected.

Thanks, I appreciate you confirming my suspicions. I took it to a local workshop, and they confirmed oil contamination due to the extended maintenance interval. An oil change and filter replacement fixed it. The repair cost 165€.
