I think it's been a while since the last oil change, to be honest. How can I tell if it's contamination for sure? And what would happen if I keep driving like this?

In my case, the oil was very dark and sludgy, not the usual amber color. Driving with contaminated oil can seriously damage your engine. It's best to get it checked by a workshop as soon as possible. They will probably recommend an oil change and a new oil filter at minimum. Consider that the oil pressure sensor can also cause this issue.

Thanks for the advice! I took it to a workshop, and you were right – the oil was badly contaminated. They did an oil change, replaced the oil filter, and the warning lights are gone. Cost me 165€ Appreciate the help!

I had similar symptoms in my Peugeot 307. Have you checked when the last oil change was done? Oil contamination can cause these kinds of issues, especially if the maintenance interval was exceeded. What does the oil look like on the dipstick?
