Stagea Brake Booster Pressure Sensor Error

I don't own a Nissan Stagea, but that sounds like an issue I had with my 2014 Opel Insignia. I also got error messages and my braking felt like stepping on a sponge. Did you recently have any work done on your brakes? Maybe a fluid change or line replacement?

Yes, I did have the brake system bled recently. What were the specifics of your Opel Insignia issue? Did diagnostics point to the brake booster pressure sensor, and what steps did you take?

The diagnostic tools indicated a fault with the brake booster system. Given that the brake system was bled recently and you're experiencing similar symptoms, the connection is likely. It's best to get it checked and re-bled properly at a workshop. The error could cause a vehicle safety fault.

Thanks for sharing your experience! I suspected the brake bleeding procedure was the issue. I booked an appointment with my workshop and the repair cost 90€. Your input helped point me in the right direction!
