Hello  
Pleas help  
the car is 2011year but kessy is 2014  
I replaced my audi a5 kessy unit and now my keyless entry does not work .The component protection is removed by the audi dealer.  
The car starts with the button but the doors are not opened by kessy.  
I have tried to parameterization a5PA\_start\_auth\_8K0907064Cx,Kx.zdc file but i got a error (writing error 34 ).My kessy unit is :8K0907064KJ  
After that i got a error on kessy (05) invalid data record !
