AWD seems to be X440440. Took them two months to send me my card, just to find out that the AWD isn't even printed on it. My Preferred profile recognizes me as participant, though.
This does give some pretty decent rates - I need a one-way rental in Brazil in January (10 days, GIG-GRU) and it came to just 317 Euros for a group C vehicle including the one-way fee. That handily beats a large number of otherwise reliably cheap AWDs I have tried, and was also significantly cheaper than using a broker (mietwagen-billiger.de).
So - yeah, that 30 CHF was money well spent
