Peugeot 1007 brake booster pressure sensor issue

I'm having trouble with my 2007 Peugeot 1007 diesel. It has only 43919 km on the clock. I'm getting an error message in the speedometer, and the braking performance feels really poor. I also had it scanned, and there's an error stored related to the brake booster pressure sensor. Is it possible the brake system was bled incorrectly at some point, triggering this? Any ideas?

I had something similar happen on my 1007! The pressure sensor went bonkers. Does the brake pedal feel kinda hard or spongy? I never thought about bleeding, but I'm keen to hear more if you've discovered a possible bleeding issue!

The brake pedal does feel a bit hard sometimes, now that you mention it, and other times it seems like I need to press it way further than usual to get the same stopping power. Could it really be connected to a bad brake bleeding job then? What exactly did you experience when yours went wrong?

Yeah, the hard pedal and weak stopping power rings a bell... It sounds pretty similar! I wouldn't mess with it. It's probably best to get it checked out by a workshop. If its the sensor like mine was, it's vehicle safety we are talking about...

Thanks a lot for your input! It's reassuring to know someone else had the same issue. I took it to the workshop, and they confirmed it was the brake booster pressure sensor, likely caused by incorrect bleeding at some point as I suspected. 90€ later, it's fixed! You were a great help!
