Mobi brake booster pressure sensor error
Summary of the thread
A 2018 Fiat Mobi is experiencing poor braking and an error message related to the brake booster pressure sensor. The issue arose after the owner bled the brakes themselves, potentially causing the sensor problem. A professional diagnosis confirmed that incorrect brake bleeding led to the sensor failure, and the issue was resolved by having the brake system properly serviced.

Yeah, I bled the brakes myself last month. I followed a guide online, but maybe I messed something up. Could that really cause the pressure sensor to fail like this?

That's likely it then! I had the same issue after bleeding my brakes. A faulty bleed can definitely mess with the pressure in the brake booster. I'd suggest getting it checked out by a professional just to be safe.

Thanks! Took it to the workshop, and you were spot on! They said the brake system wasn't bled correctly, and it caused the sensor to go bad. Cost me 90€ to fix. Appreciate the help!

Whoa, sounds scary! I had something similar happen with my Opel Corsa a few years back. Brake problems are no joke. Did you recently have any work done on the brakes?
