This procedure works with VDO dashes on CAN bus (UDS protocol) from year 2011-2013

Start software, select "VDO NEW - CAN - UDS protocol MY2011-2013" from menu. Press "Connect Selected ECU" button, after about 30 seconds software will get access to the dash.

Bootloader menu must appears on screen, otherwise this is unsupported dash, or the key is not valid! If you see "Bootloader Error!" message , this means that this dash is not supported, or wrong selection of the dashboard has been made.

It is good idea first to save the original data of eeprom memory. Press "Read EEprom via Bootloader" for that. When the reading is finished, press "File" -"Save File" in main menu and save the original data.

Press "Auto Mode" and see the next picture.

Press "Auto Mode", and wait 10 seconds. Vagtacho will read AES key of this dashboard. If AES key is good, message "Access Granted" will be shown on screen.

Important: copy-paste in a text file the information which is marked in blue! If you know AES key, you can get access to the same dashboard in future without valid key of the car!

Vagtacho will hold AES key of the last successfully read car!

Press "Disconnect", and see the next picture.

Press "Disconnect", turn OFF ignition, and remove the valid key. Insert the new key with new, not used, unlocked Megamos ID48 transponder and switch ON ignition with the new key. Do NOT close Vagtacho software ! Press "Connect Selected ECU" button, after about 5 seconds software will get access to the dash again. Press "Program New Key", a new window will be open, see the picture. Vagtacho will check the new transponder key. There will be message on screen if that key can not be programmed to the car! Check "Erase all old keys" if you wish. In this case all keys will be erased. If you left this unchecked, the new key will be added to the existing keys. No need to program all available keys again. Press "Continue" , the new key will be programmed in 5 seconds. Wait while the immobiliser accepts the new key, a message will be on the dashboard's display: "2-2" "3-3" ect. for every next key. Turn off/on ignition, and start engine. If the immobiliser's shows on display "1-2" or "2-3" this means that the type of the transponder key is not correct, or this key is already programmed to the car! Do NOT repeat the programming procedure if immobiliser shows different digits "1-2" or "2-3"! Just switch ON ignition with NEW Megamos ID48 transponder key! If you want to program more than one new key, repeat again the same procedure for every next key.
