2012 Audi A4 PTS won't start

0 votes
Everything connected correctly,I assume. The only thing I couldn't tell from the diagram and the pictures is the black ignition wire behind the fuse panel. The picture from wire diagrams had the pin pointing at nothing and was no description of which harness the wire is coming from. I looked through all the harnesses and found one giant black wire, which I assume is the ignition, so I connected to it.

audi requires the key port and emergency key to be wrapped, so I wrapped 3 times around the key port and 10 times around the emergency key and have them in close proximity behind the dash

all other functions of the evo one work with the fort in RF kit, except ignition during remote start. It is an automatic, so I cut the jumper loop. The unit programmed correctly, and the remotes programmed correctly as well.


edit. I verified that the ignition cable behind the fuse panel is correct. I also tried remote start with a fob in the ignition and it worked, so it's gotta be the emergency key and key port wiring deal. I have the key port wrapped 4 times and the key wrapped 10 times. I've redone this 3 to 4 times and still can't get it to work. I verified the emergency key works in the dummy fob,and it works. I can't actually get the key port out of the car, so I'm wrapping it while it's in its harness, but pushing the wire as far as I can to the front of the key port. I'm using a solid copper 22 gauge wire.

Its all in the wrapping of the ignition barrel, 4 times is not enough,


Wrap both the barrel and key minimum 10 times tightly, and then connect both ends of the wire that was used for the key wrap , vehicle should remote start everytime. only then do you disconnect the 2 wires for key wrap and connect it to the Evo unit as shown in the guide.


Thank you

I wrapped the key port from the back, because it's next to impossible to get out of the car, and I pushed the wraps all the way towawrds the front of the port, but the harness that the port slides into is too far from the front. If you remove the key port cover and wrap the front of the key port 3-4 times, it works flawlessly.

Please be advised that the instructions say to wrap the front of the key port, which you cannot do by removeing the key port from the car. It slides into a plastic harness that's the same size as the port, so wires will not be able to slide into the plastic carrier and still be at the front of the key port. Best option is to wrap the port from the front like I did. I've attached a picture.
