BMW X1 Multiple Warning Lights Signal Brake System Alert

Hey there! I had a similar issue with my 2013 BMW X3 last year. Those warning lights lighting up together usually points to an undervoltage problem in the ABS/DSC module. In my case, it was caused by a failing battery that wasn't providing enough power to the system. When I took it to the garage, they diagnosed it properly, turns out the battery was on its last legs and it was affecting the brake system's electronic components. The spongy brake pedal is a telltale sign. They replaced the battery and recalibrated the ABS module. It's actually quite a serious issue since it affects your entire brake system's functionality. Don't just reset the warnings, that's just masking the real problem. Make sure whoever checks it does a proper voltage test on both the battery and the ABS module. My advice? Get it checked ASAP. With those symptoms, it's not something you want to put off. Best of luck with the fix.

Thanks so much for sharing your experience, this really sounds similar to what I'm dealing with. The battery angle makes a lot of sense, especially with all those warning lights coming on together. Can I ask how much the whole repair ended up costing you? And has everything been working smoothly since the fix, or have you noticed any other issues pop up?

Hey again! Good to hear back from you! Yeah, I got the car fixed right after my last reply and I'm happy to report it's running perfectly now. The mechanic found both the brake wear issue and the undervoltage problem you're experiencing. The brake repair was straightforward, just needed new pads and rotors. For the undervoltage, they had to replace the battery and recalibrate the ABS module, which set me back 240€ total. Since the fix, my X3 has been running like a dream, no more warning lights, and the brake pedal feels solid again. It's such a relief not having those warning lights staring at me every time I start the car! The braking system is working exactly as it should now, nice and responsive. I'd definitely recommend getting yours looked at soon. It's not the kind of issue you want to leave hanging, but at least it shouldn't break the bank to fix. Let me know how it goes when you get it sorted!

Thanks for all the info! Just got back from the mechanic and wanted to update you. You were spot on about getting it checked quickly. Took it to a certified BMW specialist this morning. They diagnosed it as a failing battery and worn brake pads, exactly what you mentioned. Total bill came to about €300, not as bad as I feared. They replaced the battery, put in new brake pads, and recalibrated everything. The spongy feeling is completely gone now, and all those annoying warning lights have disappeared. Car's driving like new! Really glad I didn't just ignore those warning signs or go to someone who would've just reset the system. Thanks again for pointing me in the right direction. Feeling much better about the whole situation now that it's properly fixed!

Hello, I replaced the front brake pads and now I can't get rid of the red brake system warning light. BMW X3 2016 1.8 D 150 hp s-drive. A solution please.

Double-check that the brake pad wear sensor was replaced or properly reconnected during the pad replacement. If the sensor is damaged or not connected, it can trigger the warning light. If the sensor is fine, you may need to reset the brake system warning light using a diagnostic tool. Let me know if reconnecting the sensor resolves the issue or if you need further assistance.
