ASR Mod(Click here for a text-only version)
What is ASR? ASR is short for Anti-Slip Regulation. It is basically a safety feature where, if a wheel begins to slip, the computer applies braking force to that particular wheel, assisting to gain better control.
This mod will result in the following:
1. Will automatically disable ASR when vehicle is started.
2. ASR can be turned on by simply pressing the ASR switch after the corresponding delay time. (see below)
Listed below are the parts and tools necessary to perform this modification. I have provided several links as examples where to purchase each item. NOTE: All electrical connections were joined together by soldering. If you don't own a soldering iron, then use plastic crimp style connectors which can be purchased at Pep Boys, Radio Shack, etc.
WARNING: This mod was performed on my 2001 Volkswagen Jetta. I cannot gaurantee this will work on your vehicle. Work at your own risk. Installation times will vary upon the installer's experience. It took me about 20 minutes to complete this ASR Mod.

Procedure:
Step 1: Remove the farthest left panel piece (or driver side heated switch control) by carefully inserting a small pick or screwdriver underneath it and pulling it off.
Step 2: Remove the hazard switch by carefully inserting the small pick or flat-head around it and wiggling it out of the dash. It should slide directly out without much force.
Step 3: Look into the left hole from which you removed the panel piece and you will notice a metal pin on the side of the ASR switch. Use the small flat-head or pick and press the metal tab in while using ur other hand and pushing the switch outwards with your finger through the other hole. Do this for each side until the switch eventually wiggles out.
Step 4: Locate the Black and Gray/Black wires. Connect the positive (+) lead of the capacitor to the Black wire. Connect the negative (-) lead of the capacitor to the Gray/Black wire. Solder both electrical connections and then wrap electrical tape around each one to prevent any short circuiting.

Step 5: Plug the ASR switch back into the dash. Plug the hazard switch back into the dash. Finally, plug the left panel piece (or driver side heated switch control) back into the dash.
Note about delay time: Immediately after your car is started, there is a delay time in which you will have to wait until your able to turn the ASR back on. That delay time varies depending upon the capacitance of your capacitor. I chose to use a 35V 22µF Radial Lead. The larger the capacitance (ie. 22µF, 33µF, 47µF, etc...), the longer the delay time. With my 22µF, the delay time is approximately 7 seconds.
Note about lead type: There are two different lead type when purchasing capacitors. Axial have leads on opposite ends of the capacitor and Radial have it's leads on the same side. Radial type capacitors, for this mod, should be easier to work with.
Your finished!
