Electro-mechanical power steering assists the driver when steering.
The degree of power assistance is adapted electronically, depending on the speed.
Warning/indicator lamps and driver messages
Steering defective! Do not drive Audi A4!
If the warning lamp lights up permanently and the message appears, there may be a power steering failure.
Do NOT drive on. Obtain professional assistance.
Steering system fault. You can continue driving
If the indicator lamp lights up and the message appears, the steering response may be heavier or lighter than usual. In addition, it is possible that the steering wheel will be off centre when driving in a straight line.
Drive slowly to a qualified workshop and have the fault rectified.
Dynamic steering: initialising
If the indicator lamp flashes and the message appears, the dynamic steering* is being initialised. The steering wheel will move slightly after the engine is started. The dynamic steering may be initialised if the steering wheel was moved while the Audi A4 was stopped. The indicator lamp will go out when the initialisation has been completed.
