Operating condition

The Tiptronic control unit is in operating mode once the ignition is switched on and the internal function test is completed successfully. Within the defined limits for power supply '10.5 V to 16.5 V' and temperature, all incoming signals are processed by the integrated software and the appropriate monitoring and control processes are performed.

The solenoid valves in the transmission are guaranteed to function perfectly at a voltage of between '9.0 V and 16.5 V'.
