BMW 5 Series ABS & ASC Failure: Multiple System Issues

Hey there! I've got some experience working on BMWs. I actually had a similar problem with my 2012 BMW 3 Series (also gas engine). Those ASC and ABS warnings really had me worried at first! My workshop found that it was just a faulty ASC relay causing all those symptoms, the jerking during acceleration and the warning lights. The fix was pretty straightforward once they diagnosed it. Was back on the road the same day after paying around 90 Euro for the repair. Could you share more details about your car? Like the specific engine size and whether you've noticed any other symptoms? Also, have you had any other warning lights pop up? This info would help me give you more specific advice based on my experience. BTW, I'd recommend getting it checked soon, these issues can get worse if left unattended. Good luck!

Thanks for sharing your experience! My car's just had its latest service, and with 169256 KM on the clock, I'm definitely concerned about these issues. Those symptoms you described sound exactly like what I'm experiencing. Interesting that it was just the ASC relay in your case, that's actually reassuring since I was worried it might be something more serious (and expensive!). The jerking during acceleration is really starting to bug me, especially since my car's usually so smooth. I'll definitely get it checked out this week. Just hoping it's something relatively simple like in your case and not a major repair job. Thanks for the heads up about getting it looked at quickly, you're right, better safe than sorry with these kinds of issues.

Hey again! Really glad you found my previous reply helpful. Yeah, when you mentioned the mileage (169256 KM), it actually reminds me a lot of when my issues started, my BMW was around that mileage mark too. I totally get what you mean about the jerking being annoying, BMWs are supposed to be smooth! Just like you, I was super worried at first, thinking it might be something major with the transmission or engine. The ASC relay fix worked wonders for me though, completely sorted out both the jerking and those pesky warning lights. Quick tip from my experience, when I took mine in, I made sure to tell them about all the symptoms (the jerking, ABS, and ASC warnings). Having all that info really helped them pinpoint the issue faster. The fact that you're getting the exact same symptoms as I did makes me pretty confident it could be the same problem. Keep us posted on what your mechanic finds! Always interested to hear how these things turn out, especially since we had such similar issues.

Thanks so much for all the detailed feedback! You've actually made me feel a lot better about the whole situation. It's really helpful knowing that you had such similar issues at around the same mileage and got them fixed without any major drama. I've already called my mechanic and booked the car in for tomorrow morning. Made sure to mention all the symptoms you talked about, the jerking, ABS, and ASC warnings. They seemed to think your relay theory could be spot-on based on what I described. I'll definitely update this thread once I get the diagnosis and repairs done. Fingers crossed it's just the ASC relay like in your case! Really appreciate you taking the time to share your experience, it's exactly the kind of first-hand info I was hoping to get when I posted. Makes dealing with these car issues so much less stressful when you know others have successfully sorted out similar problems.
