OL code refused by dealer

I am quoting for 2018 new 340i and the dealer gave a good price after spending a long time for negotiation. The price is just good, but not great. it is around 13% off before incentives. I am not qualified for college graduate and loyalty. So only $4500 leasing credit is used, I will use CCA later.

After we make consensus for the sales prices and money factor, I tried to use OL code for $1000.
He told me that they will not do that for me, because the price he gave is already smoking price. And he told me that the price is all they can do for me, it does not make sense to lose money for them. But actually they are not losing money in my calculation(The rebate also should be from BMW factory).

This is the end of March. I should get the deal and should be able to use the OL code (even $500 is fine).
What can I do to make him apply the OL code ? I tried a lot ways to persuade him, but failed. Should I try to ask another salesman in the dealership to apply this OL code ?

Thanks ! Appreciate your help !
