Jumper Oil Pressure Light

I had a similar issue with my Jumper, although it took a while to surface. The symptoms you describe are concerning. It could be a faulty oil pressure sensor or a failing oil pump. Before jumping to conclusions, have you checked the oil pressure with a mechanical gauge? The dashboard light isn't always reliable. Also, what weight of oil are you using? Too light of an oil could cause low pressure, especially in an older engine. I'd also be concerned if those mechanical noises are still present after you've established correct oil pressure.

A mechanical gauge – good idea! I hadn't thought of bypassing the dashboard indicator. I'm using 10W-40, which is within the manufacturer's range for this engine. But maybe a slightly more viscous oil would be better given the vehicle's age? What happened in your case? Was it a failing oil pump, or something else?

In my case, it did turn out to be the oil pump. I tried a thicker oil as a temporary measure, which seemed to quiet things down for a short while, but the underlying issue remained. Eventually, the noises returned, and the light flickered more frequently. After the mechanical gauge confirmed low pressure, I had the pump replaced. If I were you, given the noises you're hearing, I'd get it to a workshop sooner rather than later. Ignoring low oil pressure is a recipe for disaster. The bill was about 755€.

Thanks for the advice. Your experience mirrors my situation. A visit to a workshop is now necessary. Your insights have saved me time and potential aggravation. It was indeed the oil pump which had failed and I'm happy to report that after replacement, the Jumper is now running smoothly.
