Bipper brake booster pressure sensor issue

Hey, I have a Bipper too, and that sounds awfully familiar. I was getting similar error messages and the brakes felt really weak. Check the brake booster; a faulty pressure sensor will definitely mess things up. Could also be a bad vacuum line but the pressure sensor is more likely. I'm curious, have you checked for any leaks in the brake lines?

Thanks for the quick reply! I haven't noticed any visible leaks around the brake lines, but I'll double-check. How did you end up fixing yours? Was it just the sensor, or something else involved?

Yeah, in my case all pointed towards the brake booster pressure sensor. Honestly, I'd suggest taking it to a workshop, saves a ton of headache trying to fix hydraulic brakes yourself. They replaced the sensor, did a check of the whole system and it's been perfect since. Diagnostic tools help a lot in the troubleshooting process.

Okay, awesome. That confirms my suspicions! I'll book it in with a workshop to get the sensor replaced. I saw replacement parts go for around 90€ so it is not even that expensive. Really appreciate the help!
