Workaround
As long as 'modinfo dvb_usb_af9035 | grep v07CAp0918' is empty, compilation of af9035.c and dvb-usb-ids.h with patch above is necessary:
'modinfo dvb_usb_af9035' should report:

A918R tuning is then not working as expected.
Comments
1] still some doubt on exact dvb-usb-af9035-02.fw firmware to be used (several LINK/OFDM versions tested)
2] AVerTV_Volar_HD_PRO_A835 using same components is reported to work including tuning/scanning;
3] function "static int af9035_tuner_attach(struct dvb_usb_adapter *adap)" of af9035.c does not include any gpio settings for tda18218: problem or not ? to be clarified.
Then still some hope, but no solution identified by now.
