Onix oil pressure warning light

I had something similar happen with my Onix. Check the oil color. If it looks like coffee with milk, you might have exceeded the maintenance interval by a lot. Has the oil filter been changed recently? Think of it like this: if you don't change your socks after a week, your feet will complain! Same with the car and its oil. Are you using the correct oil type and additives?

Thanks for the quick reply! I'm not sure about the oil type and additives; I usually just get whatever the shop recommends. The oil filter should have been changed at the last service, but now I'm second-guessing that. When you had the issue, did the oil look really dark and sludgy, like mine?

Yep, mine looked like thick, dark sludge. If your oil filter wasn't changed, or the wrong oil was used, that could definitely cause it. It's like trying to run a marathon with shoes two sizes too small. You'll get problems. With those km on the clock and the symptoms you described, I'd say get it to a workshop ASAP. Better safe than sorry.

Thanks a lot! I took your advice and brought it to a workshop. Turns out I had seriously exceeded the maintenance interval. They changed the oil, filter, and gave it a good flush. Cost me around 165€, but now the lights are gone and it's running smooth again. Appreciate the help!
