2005 A4 cabriolet SAFE mode - all options tried in Audi A4 (B6) Forum Posted April 1, 2020 Hi all, I'm stuck with the SAFE mode after disconnecting the battery to charge it after a full discharge (left untouched for 3 weeks). So far I have tried the following in all different sequences after charging and reconnecting the battery (key fob battery is new now): - short the cables together for 30+mins. - press unlock button whilst lock is turned to On (but not turning engine over) - press & hold unlock button before opening door, then turning ignition on, then off, then ignition back on. - prayer (no answer from the spaghetti monster) Still the bugger will turn but not fire and the SAFE is displayed on the radio. Hazards are flashing but no alarm sounds. I checked for codes with my OBD reader - nothing at all. I presume that one of the above would have re-synched my fob (if it needed it). Does anyone have any other tricks I can try before I torch, i mean SORN it ? Thanks a lot, Tony

Hi all,
I'm stuck with the SAFE mode after disconnecting the battery to charge it after a full discharge (left untouched for 3 weeks).
So far I have tried the following in all different sequences after charging and reconnecting the battery (key fob battery is new now):
- short the cables together for 30+mins.
- press unlock button whilst lock is turned to On (but not turning engine over)
- press & hold unlock button before opening door, then turning ignition on, then off, then ignition back on.
- prayer (no answer from the spaghetti monster)
Still the bugger will turn but not fire and the SAFE is displayed on the radio. Hazards are flashing but no alarm sounds.

Does anyone have any other tricks I can try before I torch, i mean SORN it ?
Thanks a lot,
