BMW X2 Brake Booster Warning Signs You Can't Ignore

Hey there! I experienced something very similar with my 2017 BMW X1. The symptoms you're describing match what I went through, weak brakes, constant pump noise, and warning lights. The root cause was actually a botched brake bleeding job from a previous service, which let air into the system. The fix required a complete brake system flush and proper bleeding sequence using a professional diagnostic tool. It was definitely a serious issue that needed immediate attention since it affected the brake performance. The technician also replaced my brake booster pressure sensor as it was damaged from the improper bleeding. If your symptoms match, don't drive the car too much until it's fixed. The brake booster pressure sensor could be the culprit, but get the entire brake hydraulic system checked. Ask the shop to show you the diagnostic readings, that's what helped confirm my issue.

Thanks for sharing your experience! I'm getting my car checked tomorrow actually. Your situation sounds exactly like what I'm dealing with. Quick question, do you remember roughly how much you ended up paying for the full fix? Also, has everything been running smoothly since the repair? Just want to make sure I'm prepared for what's ahead with this repair job. My symptoms seem identical, and I definitely agree about not driving it much, I've been keeping it parked except for absolute necessities. Really appreciate your detailed response!

Great to hear back from you! I actually just had this fixed about a month ago, and I'm happy to report everything's running perfectly now. The brake booster pressure sensor replacement did the trick, and the mechanic found that the previous shop had messed up the brake bleeding process, just like I suspected. The total bill came to 90 € for the complete fix, including the proper brake system bleeding. Honestly, it was worth every penny because the brakes feel so much better now, no more weird noises or warning lights, and the brake response is back to normal. The hydraulic pump's working just as it should, nice and quiet. You're definitely doing the right thing getting it checked right away. It's not the kind of problem you want to ignore. Let me know how it goes at the shop tomorrow, I'm curious to hear if they find the same issues mine had.

Just got back from the mechanic and wanted to update you. You were spot on! Turned out my brake system needed a proper flush and the sensor was toast. The mechanic showed me how air had gotten trapped in the lines from a previous bad service job, exactly what happened to you. Total cost was a bit higher than yours, but still reasonable for the peace of mind. The best part? The brakes feel amazing now! No more warning lights, weird noises, or that scary weak brake feeling. The hydraulic pump's running quietly like it should. Really grateful for your advice about getting it checked right away. You saved me from a potentially bigger headache. The mechanic even complimented me on bringing it in before the problem got worse. Everything's working perfectly now. Thanks again for your help!
