Expert brake booster pressure sensor issue

Hi, I'm having a problem with my 2014 Peugeot Expert diesel. I keep getting an error message, and the braking feels poor. I had an error stored in the error memory pointing to the brake booster pressure sensor. Could this be related to a brake system issue, maybe air in the lines? The van only has 53597 km on the clock.

That sounds familiar. I had a similar issue with my Expert. It's like trying to stop a runaway train with a bicycle brake! Could be the brake system was bled improperly at some point. Does the pedal feel spongy at all?

Yes, the pedal does feel a bit spongy. Is it definitely the same issue, and is it safe to drive?

While I can't say definitively without seeing it myself, the spongy pedal and sensor error strongly suggest an issue with the brake booster system. Air in the hydraulic lines can cause that. It's best not to drive it more than absolutely necessary until it's checked. Brakes are kind of important for, you know, not crashing. I'd advise you to have it looked at by a professional mechanic as soon as possible.

Thanks for the advice! It was the brake booster pressure sensor, likely caused by incorrect bleeding. Had it sorted at the workshop for 90€. Brakes are working perfectly again now.
