2008 audi a6 remote start

Pitstop mode flashes the lights 3 times like it's taking over, then when I take the key out of the ignition it shuts off, but I'm not sure if that's how the module operates. Does the pitstop mode work with this module and the electronic key cylinder? I know it's different than cenventional. I did use a 556U to bypass the transponder chip. I've gone over the wiring countless times. This is literally going to be the first remote start I can't get to work in 18 years doing this. I even tried putting power to the ignition circuit after it's started to see if it was dropping out somehow and that did nothing either. Just hate giving up on a car that I can get to start but then won't stay running. It's just so bizarre.

The 556U, did you use the loop or follow the instructions and wire it Euro style, also did you obtain a valet key from an Audi dealer for the 556 and did they program it for you to pair with the car?

i just pulled up installogy info for it. the ign start and acc wired at the ignition tumbler are for sense only. they tell the computer to power the appropriate circuits. you need to go to the fuse box and look for the larger gauge wires those will be the correct ign and acc wires.Ted

Figured it out finally. The part that was messing with me is I could hotwire the DBALL and it would start and run, but with the remote start connected, it wouldn't. It ended up being that the DBALL was not properly outputting brake signal AND the status output was not strong enough to trigger both the 556U and the DBALL for some reason. I put a relay on the status for a stronger ground and hardwired the brake circuit and all is well now. Works fine. The part that screwed me up and why I didn't figure out that it was the brake sooner is that the car will actually turn on for about 15 seconds by just pulsing the ignition wire, which the Compustar brain would do when it first fired up, but would not keep the ignition circuit powered up because the brake was shutting it down. Stupid problem!!!!!!!!
