ASTRA-G ISO14230 PERIODIC TX AUTO ANSWER NOT OK. HELP!

[dock]

I am using odb2 interface with elm and several common commands are working pretty fine, however when i try to use the Periodic Transmission mode, auto repeat answer, the ECU reply with the first answer ok but stop and do not enter in continuous answer mode.

I send the command 10 82
it answer 50 82
.. and stop.

It should after 50 82, continuously send the last answer repeteadly.

I´m using the following manual
http://www.alfa145.co.uk/obd/14230-2s.pdf
page C4

Is something wrong?
