Speedometer light and suspicion of worn brakes on 2020 Ford C-MAX
(Translated from German)
Summary of the thread
A 2020 Ford C-MAX owner is concerned about a warning light on the speedometer, suspecting it might be related to worn brakes. A similar issue in a 2017 Ford Focus was due to communication problems between control units, resolved by cleaning connections and resetting the ECU software. It is suggested that the ABS sensors might be dusty, causing the warning light. The owner is advised to have the car checked by a mechanic to diagnose and resolve the issue.

Hey, thanks for sharing your experience! It's really reassuring to know that it doesn't have to be a disaster. Do you happen to remember what you ended up paying for the whole thing? And did you have to struggle with anything afterwards, or did everything run like clockwork? Hope your Ford is doing well! Thanks in advance!

Hey, sure, no problem! If I remember correctly, I had to pay around €955 to fix the communication problem between the control units. Not exactly a penny, I know, but my old Ford has been running smoothly ever since. And to come back to your suspicion about the brakes: There was actually something wrong with my car too, they were pretty worn out. But since the visit to the mechanic, this has been fixed and I no longer have any problems. I hope I was able to help you and that your Ford C-MAX will soon be fit again!

Thank you! That really helps me. Wow, €955 is quite a chunk, but if the car drives like it did before, it might be worth it. I definitely need to have a look at the brakes. I hope it's nothing too bad with my C-MAX and that it gets going again soon! Thanks again for your explanations and advice! Stay safe and keep your Ford safe too!

Hello, don't worry! I had a similar problem with my 2017 Ford Focus. In my case, it was a communication problem between the control units. My mechanic jacked the car up and had a look underneath. He had to remove some components and check them. It turned out that some connections were not working properly and were interfering with the signals between the control units. So he had to both clean the connections and reset the ECU software. It was definitely a bit of a pain and took a day, but don't worry, it's not a disaster. P.S. It could also be that your ABS sensors are just a bit dusty, which can also cause the warning lights to come on. It's best to have it checked. Good luck!
