4808F2 är ett fel som lagrats i din BMW:s minne (en ISTA-felkod, inte en standard OBD-II P-kod).
Vad det betyder: 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.
