Trying to program my 2013 Audi Q5 with EVO-ALL or AUDT1 or EVO RS. I really don’t know because all three of those are on the box that it came in, which is confusing in itself. I’m using the T harness that came with it, and I spliced into the brake switch connector and the CAN hi and lo wires. T plugged into the key port. I flashed the EVO using the software and FlashLink. I can get through steps 1-4, but at step 5, I push key in to power on vehicle, the blue light comes on, I press and release the programming button on the EVO, the light goes out, but never comes back on to flash repeatedly as the instructions say it should.
