Starter interlock relays and CCM

Hi all, can anyone with a bentley manual help me out with the location of the two starter interlock relays. I believe one looks for a signal from the neutral safety switch, the other one looks for a CCM signal. The one that looks for the CCM signal is the one that interests me. I know the question will come, therefore I'll answer it in advance, I'm looking to bypass the interlock relay so I can take the CCM out of the loop and remove the 10 lbs of associated wiring. I know I should own a manual, but when you have great forum support like the TT have, you tend to get spoiled. Any help greatly appreciated! :)

I can get it for you when I get home from work today, Max. Unless someone gets it to you first.

By CCM is that the comfort control module??

As in this bugger...



If so i'd be really interested in your plans to delete the thing, as you say, there's a shed load of wiring for that thing!!
Yes Nick, the comfort control module. The box and associated wiring is over 10 lbs (the whole wiring branch on the RH side of the floor board is dedicated to this crap). It serves no purpose except comfort and alarm functions, no business free-loading on a track car. I already cut the wiring off, just need to bypass the the starter interlock over the weekend... Yeah, I'm that commited with my mods, delete first and figure out later. :mrgreen:

PS: I'll let you know how I bypass it!

A Bentley manual for an Audi would be a little out of place on my desk at work. :lol:

I have pdf's of all the wiring diagrams If you want them

Am pretty sure I have all the relay locations too
Please do share the wealth Matt! 8)

Just finished completing the bypass. It is pretty simple to do once you understand the function of the Comfort Control Module J429 (aka Control Moduke for Central Locking) and what the car is looking for in order to start. Let me first say that the module controls a host of operations and bypassing it might not be a good idea for a normal street car. The CCM overlooks things like central locking, anti-theft warning, and what interests us here, sending a power signal to the starter interlock relay J207 (obviously once all the proper conditions are meet).

So in normal operation, and once all the checks are performed by the CCM, it sends a power signal to the the J207 relay (that's what we want to simulate to get the car running without a CCM). This relay is located in the 13-fold realy panel in the #4 position.

Below is what the relay will look like, and you want to romove it and unclip the plug so you have easy access to pull the wires.

Here are the circuits labeled on the relay. You want to jumper circuit 85/86 and then 87/30 (separately). I just pulled the lines off the plug, labeled for future use, jumped the circuits shrink tubed and tuck everything away. Done!

As I thought, the CCM also references the clutch inhibitor switch F194. However, jumping J207 like mentioned is downstream of the clutch pedal position switch (CCP) and it can be simply left alone.

Here is a diagram of the circuits:

PS: Thanks to Matt and Adam for providing me with some much needed wiring diagrams for the car. You guys rock and allowed me to drop about 10 lbs of useless junk!
