Renault Master Oil Pressure Warning

Sounds familiar. I've got a Renault Master too. I had a similar issue. Did you check your oil for any contamination? It might be worth looking into. Also, when was the last time you changed your oil filter?

Contamination, huh? How would I know if the oil is contaminated? I haven't checked it for that. And the oil filter... I can't remember exactly when it was changed. Maybe it's been a while. What kind of contamination are we talking about?

Well, mine was sludgy, thick, and darker than usual. If it looks or feels different, that's a sign. Given the oil pressure light, and if you can't remember the last filter change, it really points to that. I’d say it’s best to get it checked at a workshop before things get worse. Ignoring it could mean major engine damage, and that's a whole different level of expensive.

Thanks for the advice! You were right, I took it to a workshop, and the engine oil was contaminated because I exceeded the maintenance interval. They changed the oil and filter. The oil pressure light is now off and the final repair cost was 165€. I'll definitely keep a closer eye on the service schedule from now on!
