Hey, thanks for sharing your experience! That's actually really helpful since I've been worried it might be something more serious. Quick question, do you remember roughly how much you ended up paying for the fix? And has everything been working smoothly since they repaired it? Just want to get an idea of what I'm looking at cost-wise and if it's likely to be a long-term solution.
Hey again! Happy to give you an update! Yeah, everything's been working perfectly since I got it fixed. The parking sensors are now working like a charm, no more of that annoying constant beeping that was driving me up the wall! The total bill came to 95 € for fixing the cable and plug connection. Pretty reasonable, if you ask me, especially since I was worried it might be something way more expensive. The mechanic showed me the corroded connector they replaced, and honestly, it was a simpler fix than I expected. It's been a few weeks now, and I haven't had a single problem with the parking aid system. Works just like new when I'm backing up. Definitely seems like it was a long-term solution, not just a quick patch-up job. Hope this gives you a better idea of what you might be looking at! Let me know if you need any other info.
Thanks so much for all the details! Actually, I just got back from the mechanic yesterday and you were spot on! It turned out to be almost the exact same issue, corroded wiring connection on the rear sensor. I ended up paying a bit more, around 120 € total, but they also did a full diagnostic check of the entire parking system while they were at it. Took them about an hour to fix everything up. The mechanic showed me the damaged parts and explained what caused the problem. The best part? No more annoying beeping! Tested it out in the parking lot right after, and all the sensors are working perfectly now. Such a relief it wasn't something more serious with the car's computer system like I initially feared. Really appreciate you sharing your experience, it definitely helped me know what to expect when I went in. Fingers crossed it stays working as well as yours has!
Hey there! I had a similar issue with my 2016 BMW M3 last month. The constant beeping in reverse was driving me nuts too. Took it to the garage and turns out it was just a faulty connection in the wiring harness for the rear sensors. The mechanic found that moisture had gotten into one of the main connector plugs, causing corrosion. They had to clean the connections and replace one damaged sensor harness. Not a major repair, honestly, more annoying than serious. My case ended up being a straightforward fix, but I'd recommend getting it checked soon since those sensors are part of your safety system. Better safe than sorry. Hope this helps with your decision!
