Looking for advice on how to rectify an electrical failure in the VW Polo Diesel 2016: Experience with Flex-Ray-Bus faults

Hello, I know the problem quite well. I experienced the same thing with my 2014 VW Golf, which is pretty similar to yours. First of all: I'm not a car expert, but I have had problems with my car on one or two occasions. So just a low-level experience, I would say. This ominous error message prompted me to take my car to the garage. There they discovered that the control unit was faulty. It seemed relatively expensive to me at first, but I ended up paying just under 1000 euros for the complete repair. It could be something similar in your case, so it would certainly make sense to visit a garage. But before I guess any further, can you give me some more information about your vehicle? For example: How many kilometers does it already have on the clock? Did you buy the car new or used? Best regards!

Hey, thanks for your answer. My Polo already has 47435 km on the clock and my last inspection was not too long ago. I've heard about this ECU thing, but I wasn't sure if that could really be the problem. I think I'll follow your advice and take the car to the garage. 1000 euros sounds a lot at first, but if it solves the problem, then it's worth it. I'll keep you up to date! LG

Hello, I'm glad I could help you. Yes, the control unit is a tricky thing. It may well be that this is also the problem for you, especially if your vehicle has been on the road for a while. This mileage also means that some parts could be showing signs of wear, even if the car is regularly serviced. I would definitely recommend having this checked by professionals. Of course, I hope it won't be quite so expensive for you. Sometimes a simple reset of the control unit can help. And who knows, maybe you'll get lucky and it's something completely different that's easier and cheaper to fix. It would be great if you could keep us up to date. It would be great if others could learn from your experience. All the best and hopefully your Polo will soon be fit again! Best regards!
