Does it do auto detect VIN? if not, try accessing it by manually adding VIN number. Might be it is asking for a build code too? You should be able to find that on a sticker in the door post or in the engine area. Completely stupid system since a lot of stickers are 'gone' already.
Peugeot is always a trick to get the right ECU selected before you can do anything (else it will come up with 'no communication').
I already pushed on Autel too get the auto recognition fixed, it is not true that it cannot be done since Bosch, Delphi and others can connect to the system automatically also so Autel has to get it done too. Especially on Peugeot, citroen and renault since they tend to make a mess out of their car's (electronic wise) and change systems more times then any other manufacturer.
