Don't waste your money. Program in mechatronic module is different. You would also not be able to change Audi program to BMW one using WinKFP. It can only be done in-circuit. If you have a suitable flash programmer, you could theoretically copy flash from BMW to Audi, but you would not find any instructions or guides for this.
