A back-up system is in place should a fault occur in the control system.
If all the gears are highlighted at once in the instrument cluster display, a system malfunction has occurred. In this case, the S tronic® gearbox will switch to a backup programme. In certain cases, you may not be able to select reverse gear.
Caution!
If the gearbox should ever switch into the back-up programme you should take the Audi A1 to a qualified workshop as soon as possible.
