Was bedeutet der Fehlercode?
On the V60, the brake control module (BCM) has received too low a signal from the pressure and temperature sensor for the brake booster control pressure. The sensor sends two signals, one pressure and one pressure with temperature, and when the pressure does not match the requested brake pressure, the assist functions can be affected.
Mögliche Ursachen
- Air bubbles in the brake fluid
