Install of evo-Audt1 into my 2015 Q5

Question

Hello,

I need to speak with someone regarding the installation of an evo-all system into my 2015 Audi Q5.

I am an automotive Technician and am currently trying to install the Evo-Audt1 into my vehicle.

I chose this kit, due to the simplicity of the t harness and not wanting to tap into many wires behind the key port.

Prior to purchase, I compared OEM and Fortin diagrams, and found very minor differences, but none with the T harnesss/key port plug side of things.

Looking at OE wiring diagrams. There seems to be no differences between the 2014 and 2015 Audi Q5 as far as the anti theft/key wiring goes.

I wanted to know on yalls end what the difference might be as to why I am unable to use the T harness to complete my installation.

I’ve tried using programming for a 2015 with the correct options, as well as a 2014. To no avail, although, the 2014 option seemed to work best, just was unable to decrypt the key when I got to that step, as expected.

When I do the 2014 programming procedure ( guide 77151 ), i get to step 8, which then the module flashes red rather than alternating red to yellow.

I’m really Looking for a technical description as to why this is the case, what is different, and what I could do with what I have installed into the vehicle ( evo-audt1 ).

Thanks.
