Malfunctions in the park distance system and electrical malfunctions in the 2016 BMW 4 Series petrol engine

Hey, I had a similar problem with my 2014 BMW 3 Series. The warning light in the speedometer was also constantly on and my infotainment system was acting up. After driving around like that for a while, I took it to the garage. It turned out that there was quite a mess with the vehicle electronics. The main problem was the control unit for the driver assistance system. After they replaced it, everything ran like clockwork again. So it's possible that you could have something similar. Have a look to see if that could be the problem. Good luck!

Hey, thanks for your reply! Interesting that you had a similar experience. Can you remember how much you ended up having to pay when the control unit was replaced? And were there any other incidents after that or was the problem solved for good after that? Thanks again for your help!

Hey, no problem, you're welcome! Well, I had to fork out €355 to fix the parking aid control unit. Maybe it's similar for you, no guarantee, but it could be. And since I've been to the mechanic, the problem with the faulty parking aid has disappeared. In short, I haven't had any further incidents since. So I would suggest you get it checked out. That can only help, can't it? Hope that solves your problem too!

Hey, thanks for the info! 355€ doesn't sound so bad if the problem is really gone afterwards! Your words really give me hope. I will definitely go to another garage and have the parking aid control unit checked. Let's see if that's the problem for me too. Thanks for your suggestion and support! I will keep you up to date.

Hello, I also had a problem with the PDC sensor, but it was really only the beeps that didn't work for me. You can check them relatively easily by engaging reverse gear and placing a finger on the sensor. If the sensor is OK you will notice a very slight vibration, if the sensor is defective you won't notice anything. I didn't notice anything with one sensor, so I thought the sensor must be defective. I then checked the sensor plug, which was ok. So I ordered a new sensor and installed it, since then everything has been ok again.

Carly indicated a fault with the rear right parking aid. This was changed. Approx. 1 week later, the parking aid is not working again. Carly shows nothing

What could be the error?

Check the wiring and connections to the rear right parking sensor for any signs of damage or loose connections. Sometimes, a faulty connection can cause intermittent issues. If everything looks fine, consider swapping the sensor with another one to see if the problem follows the sensor or stays with the location. This can help determine if the issue is with the sensor itself or elsewhere in the system. Let me know how it goes or if you have any further questions!
