Problems with Mercedes GLE Class Diesel 2015: Oil light and warning light - Possible causes and solutions

Hello, I had similar problems with my 2017 Mercedes GLC Diesel. I would classify my expertise with cars as rather low, but I have gained a bit of experience through such incidents. At my garage, it turned out that the problem was not the engine oil pressure switch, but incorrect engine oil in the engine. They changed the oil and cost me 175 euros. Since then, the car has been running like clockwork again. A quick tip: It would be helpful if you could give us more information about your vehicle. Then we might be able to help you better. For example, which oil you use or when the last oil change was carried out.

Thanks for your help! So the engine oil I'm using is the recommended one from Mercedes, and the last oil change was done just over 15k miles ago, at a mileage of 184248k miles. It could be that the oil is the cause, at least that seems reasonable. Will check that first. Thanks again!

Hey, no problem, that's what we're here for! You're right, your oil change intervals seem to be absolutely fine. If you're using the recommended oil from Mercedes. Have you ever had the oil filter checked or changed? I've found that a clogged or aged filter can sometimes be the cause of the engine not working properly. This may help. If the problem persists, I would definitely have a professional take a look. It could also be that there is something bigger behind it. On my GLC, I also changed a few other things in addition to the oil change, such as spark plugs and air filter, to make sure that everything was in perfect working order. Maybe that would be something for your GLE too? In any case, stay tuned and let us know how it goes. I hope this helps you! Keep us posted and good luck solving the problem!

Thanks for the advice! I actually haven't checked the oil filter yet, that seems like a good next step too. I will check the filter and consider changing it. I think the idea of replacing a few other things in addition to the oil change makes sense too. I'll get back to you as soon as I know more about it. Thanks again for your help and advice!
