A(z) 4808F2 egy hiba, amely a BMW memóriájában van tárolva (ISTA hibakód, nem szabványos OBD-II P-kód).
Mit jelent: Rear axle steering (Integral Active Steering / HSR): implausible rear-wheel steering-angle signal. May show «Chassis function restricted» / «Integral Active Steering failure». Common causes: aggressive driving/bumps, dirty/faulty angle sensor or power loss, wear/binding of the rear-axle actuator, damaged wiring/connector. If the message and steering behave normally — often a one-off; if it recurs, needs diagnosis.
