I checked for some rentals and the codes that work for me are A177232 (USAA) and B999000 (AVIS Employee??). I looked up the USAA AVIS rental benefits it seems that there are a few mentioned at http://www.avis.com/car-rental/html/...faq.html#ans12

I am having second thoughts on using the USAA codes in case I get into an accident. My guess is that once that happens, your AWD code gets looked at to see if you qualify for any waivers and at that point it might become apparant to AVIS that the usage of that code is invalid for my rental. (I waive all insurance coverages at the time of rental). Has anyone have any experience with this kinda situation? My real fear is that not only will AVIS invalidate the code after the accident (I can live with that) but AMEX will not allow me to use the Premium Rental Protection because I committed "fraud" in the first place.

The other code B999000 seems to be too good to be true. If I actually use the avis.co.uk site and use this code on top of that, I am getting luxury car (with LDW/SLI included) for a ridiculous amount. It is discounting the full sticker price by about 80~90%, which I am sure will guarantee a second look at my reservation. I read some older threads, and it seems that this code is a big trouble.
