you need emulator for your car , otherwise many thing needs to be replaced .

And why a lot elements should be changed? Ive retrofited to 2010 11 nbt and what had to be change was zgw. Only one issue left - PDC button not fuctioning. other things works as they should.

i am glad that i am not one of your customers , I would like to know the excuse you give to your customer for something like PDC button not working . 

we professional people don't offer anything that doesn't work 100% , the price of another ZGW is more than the price of the emulator , the different is that everything works as factory fitted .

What a coincidence! Im glad that your not my costumer! also costumer knew that it will not work, ofcourse it can be made to work after icm replacement :P price of ZGW depends on country, for example for 8sk ive paid 70euro - so that price is same as for emulator but its way better than emulator.

Could you tell me where to by emulator same price $70 as ZGW ?
I often use bimmerretrofit emulator cost $565 shipped
