Audi Friends and Family Certificate - how much do dealers get reimbursed on the back end?

So I just got a genuine Audi Friends and Family certificate for being on a private Audi forum.
Mine has an Audi control number and employee title & name on it along with my name on top.

The certificate says “$300 over dealer invoice” and can be stacked with eligible incentives/rebates.

It’s only for new '17, '18, '19 Audi excluding the eTron, R series, Q8, and TTRS.

Does anyone know how much the dealer gets reimbursed by Audi for using this certificate ?

Will the certificate help negotiate beyond the dealer discount ?

This cert is a waste of time. Dealer doesn’t get anything in the back end. You can negotiate a much better deal than 300 over invoice on most 2018’s now.

Yeah depending on your location you can get several thousand below invoice.

Thanks for the informative responses!

That’s why I learn so much on this forum!
