Xcent brake booster pressure sensor error

My 2014 Hyundai Xcent diesel (163138 km) has a brake booster pressure sensor error and degraded braking. I suspect incorrect bleeding. ABS is also implicated. Anyone seen this?

Summary of the thread

A 2014 Hyundai Xcent diesel exhibited a brake booster pressure sensor error and degraded braking, with the ABS light illuminating intermittently. The suspected cause was incorrect bleeding, but a workshop visit confirmed a faulty brake booster pressure sensor. Replacing the sensor resolved the braking issues and cleared the error.

I had similar issues with my 2018 Opel Astra. Got the error message and weak braking. Is your ABS light on too?

Yes, the ABS light illuminates intermittently. What was the diagnosis and fix for your Opel Astra?

Turned out the pressure sensor was faulty. Better take it to a workshop; they'll know what to do. In my case, it was the same, ABS light and everything.

A workshop visit confirmed the brake booster pressure sensor was the issue. The repair cost 90€, including parts and labor. Braking is restored, and the error is gone. Thanks for the advice.
