BMW X2 Warning Lights: Coolant & Engine Alerts Decoded

Need advice: BMW X2 (2022) coolant and engine warning lights! My 2022 BMW X2 (gas engine, 27,643 km) started showing coolant temperature and check engine warnings. Scanner shows error codes. Coolant seems low. Had a bad experience with my last mechanic and hesitant to go back. Anyone dealt with similar issues on their X2? What was the actual problem and repair cost? Looking for recommendations on what to check before taking it to a shop.

Hey there, I have a 2019 BMW X3 and dealt with similar warning lights last month. Initially thought it was just low coolant, but the diagnostic revealed a faulty coolant level sensor connector. The wiring harness had some corrosion at the plug, causing intermittent connection issues and triggering both warnings. Had it fixed at a certified shop, they cleaned the connector, replaced the damaged section of the wiring harness, and topped up the coolant. Pretty straightforward repair but definitely needed professional attention since it involved electrical components. Not a massive issue, but something you don't want to ignore. Would recommend checking your coolant level first (when engine is cold), but given both warnings are on, you'll likely need a proper diagnostic. These sensors are pretty reliable when working correctly, so when they act up, it usually points to an actual problem that needs addressing.

Thanks for sharing your experience with the sensor issue. Glad you got it sorted out. I had similar warnings on my X2 last year, and it turned out to be a similar electrical gremlin. Do you remember roughly how much the repair set you back? Also, just curious, have you had any other sensor-related problems since they fixed it? Worth knowing if I should expect more issues down the line.

Hey again! Yeah, I took care of that sensor problem, cost me 95 € to fix that pesky cable connection. The mechanic found some corrosion in the wiring harness connector and got it all cleaned up. They also topped up the coolant level while they were at it, which solved the low coolant warning. I'm happy to report I haven't had a single sensor issue since then, the warning lights have stayed off and everything's working like a charm. It's been about a month now, and the car's running perfectly. To be honest, I was worried it might be something more serious at first, but it turned out to be a pretty straightforward fix. One tip though, it's worth getting these warning lights checked out quickly when they pop up. Even if it seems minor, catching these things early usually saves headaches later on. My BMW's been solid otherwise, so I think this was just one of those unusual electrical quirks that pop up sometimes in modern cars.

Just got back from my mechanic and wanted to share what happened. Turns out the issue was pretty similar to yours, had a failing coolant temperature sensor and some wiring problems. The repair was actually cheaper than I expected, around 85 bucks including parts and labor. They found a small crack in the wiring insulation that was causing the unusual warnings. The funny part was watching the mechanic trace the problem. He kept mumbling about modern cars having "too many computers" while checking all the connections. But hey, he fixed it in about an hour, and I haven't seen those warning lights since. Really relieved it wasn't anything major with the engine. Thanks for recommending getting it checked quickly, you were right about catching it early. Much better than waiting and risking bigger problems. Think I've finally found a decent mechanic too, which is a huge relief after my last horrible experience.
