A back-up system is in place should a fault occur in the control system.
The automatic gearbox switches to the back-up programme if a fault should occur in the control system. This is indicated by all segments of the display panel either lighting up together or going out completely.
It is still possible to move the selector lever to all positions. The manual shift programme (tiptronic) is not available when the backup programme is active.
Vehicles with tiptronic gearbox: When the selector lever is in position D or S or in the manual shift programme, the gearbox will remain in 3rd gear if 1st, 2nd or 3rd gears were engaged when the fault occurred. The gearbox will remain in 5th gear if 4th, 5th or 6th gears were engaged. The gearbox will then engage 3rd gear when you drive away from a standstill or after the engine is restarted.
It will still be possible to use reverse gear in the normal way. However, the electronic lock for reverse gear will be switched off.
Should the gearbox ever switch into the back-up programme, you should take the vehicle to an Audi dealer or qualified workshop as soon as possible.
