V40 Brake Booster Pressure Sensor Failure

Hey, I've got a perplexing issue with my 2000 Volvo V40 with a gasoline engine. It's got 222285 km on it. I'm getting a brake booster pressure sensor failure. An error message is glaring at me from the speedometer, and the braking is diminished. A diagnostic scan revealed an error. I suspect an improper brake bleeding procedure. Anyone encountered something similar? I'm concerned about vehicle safety, especially the ABS and hydraulic brakes. The brake pedal is spongy!

Hey, I think I know what you're talking about. I had something similar happen with my V40! The brake pedal felt super soft, and the ABS light was on. I remember thinking it was the end of the world. Did you try checking the brake lines for any leaks?

Thanks! Could you elaborate on the specifics of your experience? Did your V40 show the same error message? What steps did you take to fix it?

Yep, the error message was exactly the same, and the braking was terrible. Honestly, I didn't mess around with it too much myself. I took it straight to a workshop because brakes are kind of a big deal for safety, you know? They sorted it out pretty quickly.

Thanks for sharing your insights. Your advice has been invaluable. It seems a visit to a trusted mechanic is the most prudent course of action. The workshop confirmed my suspicions: the brake booster pressure sensor was faulty, likely due to improper bleeding. The repair set me back 90€, but peace of mind is priceless!
