Anyone have a wiring schematic for an 03 Audi A4, either the ccm module or the factory keyless?

I already tried directwire.

Im trying to add a remote start to my factory remotes, but i need to figure out what wire

to interupt so my factory keyless will still operate while the the car is remote started.

The factory remote doesnt work once the ignition is on.

Any help would be great!

Don't even try this one, it's all done by CAN, you'd need an Audi specific by-pass.

Actually I had a thought, the factory lock/alarm module should be in the left hand rear wedged in just in front of the rear lights.
find the lead probably BLACK/ blue that goes to 12volts+ when the ignition is turned on.
Use the GWR or status output from your R/S to a relay to open circuit this wire. It might work.

Howie, that's not going to work. The comfort system control module does not have a switched 12V connection. Seems that it is a data signal that controls that function.

As per my first post, maybe the second one was wishful thinking!
In truth I try to run away from any Audi after 2002.

I guess im gonna have to put in a whole unit. Was kinda wanting just to carry around just the factory remote only, but i guess not.
