BMW Hybrid Oil Sensor Nightmare: Multiple Alerts & Errors

Had the same issue with my 2017 BMW 530e Hybrid last spring. Started with those exact symptoms, oil pressure warnings, system errors, and couldn't get an accurate reading on the oil level. Turned out the oil level sensor connector was corroded and had a loose connection. Initially thought it was more serious, but my regular BMW technician diagnosed it quickly. The repair involved cleaning the connector pins and replacing the wiring harness for that section. Not a major repair, but definitely needed a specialist who understands the hybrid system's quirks. While they had it open, they found and fixed a few other small connection issues that could've caused problems later. The whole job took about half a day. These sensors are pretty sensitive in the hybrid models, and it's worth getting it checked soon to avoid any real oil pressure issues. My advice: Find a certified BMW technician with hybrid experience. This isn't something you want a general mechanic messing with, especially given the complexity of the hybrid system.

Thanks for sharing your experience! That's really helpful since it sounds exactly like what I'm dealing with. Been wondering, do you remember roughly how much you ended up paying for the repair? Also, has everything been running smoothly since they fixed it, or have you had any other sensor issues pop up?

Hey again! Happy to help with an update about my repair. Yep, I can tell you exactly what it cost me, 95 € to fix the faulty sensor connection. The mechanic found it was just a dodgy cable connection that needed sorting out, pretty much exactly what they found with your car. The really good news is that since getting it fixed, my 530e has been running perfectly, no more annoying warning lights or oil level reading issues at all! It was such a relief when it turned out to be something relatively simple and not too expensive. These hybrid BMWs can be tricky beasts, but sometimes it's just these little electrical gremlins that cause all the drama. In my case, once they sorted that connection issue, everything went back to normal. Haven't seen a single oil warning message since then, and it's been great. Honestly, getting it properly diagnosed by someone who knows these hybrid systems was key. Worth every penny to have it done right and not have to worry about it anymore!

Just got back from the mechanic and wanted to close the loop here! You were spot on about everything. My issue was also a faulty connector, though mine needed a full sensor replacement since the previous one was completely shot. The whole thing cost me a bit more than yours, around 180 since they had to replace the part. But honestly, I'm just relieved it wasn't anything major with the hybrid system. My mechanic also cleaned up some other connections while they were at it, just to prevent future issues. Took it for a drive afterward and all those annoying warning lights are finally gone! No more stress every time I start the car. Really appreciate everyone's input here, helped me avoid going to my old mechanic who probably would've charged double and taken way longer to figure it out. Think I've found my new go-to mechanic too. They really knew their stuff about hybrids, plus they took the time to explain everything they were doing. Definitely keeping their number handy for future repairs!
