Chevrolet Beat brake booster pressure sensor issue
Summary of the thread
A 2017 Chevrolet Beat exhibited a brake booster pressure sensor failure, leading to an error message on the speedometer and weak braking. The issue arose after the brakes were bled, suggesting improper bleeding introduced air into the system, affecting pressure readings. The solution involved re-bleeding the brake system and replacing the faulty sensor, resolving the problem and restoring proper brake function.

I did bleed the brakes recently, yes. Is it possible I messed something up in the process?

Yep, that could very well be the culprit. Incorrect bleeding can introduce air into the system and throw off the pressure readings. It might be worth getting it checked by a workshop. They'll have the tools to properly diagnose and rectify the issue. Probably something went wrong in the ABS unit. Is it worth risking your vehicle safety for a faulty ABS system?

I took it to a workshop, and you were spot on. They said the brake system hadn't been bled correctly, which caused the sensor to throw an error. They re-bled the system, replaced the faulty sensor, and the total cost was 90€. Everything's working perfectly now!

Hmm, sounds familiar. I had similar symptoms with my 2019 Opel Corsa after a brake service. Error messages, poor braking... Did you recently bleed the brakes or have any work done on the brake lines?
