To answer: "Am I losing my mind" NO, that was clearly already lost years ago when I decided to buy a T1 Touareg lol
Car: 2004 Touareg V8 Air Suspension Non-Navi
Owned: 2 Years
Just last week I have fallen victim to the dreaded battery drain. Drive it all day, voltages are good, park it, voltages are good, come to it the next morning... dead as a door nail.
--Checked Driver Seat Ground, swapped battery (current one was only 3 years old), still same old story
--As best I can tell the alternator cable TSB was preformed, but not sure, when I looked it up it said it had no active TSBs
--Tried doing a voltage drop test on the fuses while tricking the car into think it was locked with the doors closed, nothing stood out
--Tried doing a parasitic draw test on the battery, seemed to be in spec during the hour I was testing it (.6 amp draw for a minute or so when pulling a fuse or activating something then drop to 0.02 amps if memory serves)
Now we come to Kessy.... about 12 months ago it started acting up, wouldn't unlock unless you pulled the handle, would immediately unlock itself after locking it with the keyfob if you were too close to it, then it just stopped working all together 6 months ago, and just left me with the keyfob only.... no biggie, I could live without it.
Vagcom codes, if you clear they come right back after reconnectihng to the module
--(when viewing the measuring blocks for the door handle buttons, none read as stuck on active, all work minus the passenger rear which does nothing)
--I also logged the buttons for 2 hours to see if maybe one was getting triggered.... not that i could see
Now all of a sudden I am having this battery drain issue. Its also somewhat sporadic, sometimes it will go 3 days, the 1 day then 1 day, then 3 days, its really weird. So I thought, well maybe the Kessy is finally playing a role in this. So I went to yank it out tonight so I could replace the resistors and MOSFETs using parts I ordered from Mouser. However in the process of doing so, I found this seemingly out of place yellow wire running from the Kessy up to what looks to be the cluster. Its ziptied to the bottom of the dash panel with new zipties.
In the "Push Button" install guide I dont see a yellow wire coming down in the same fashion mine is:
What is this wire? Is it supposed to run this way?
It meets up with this thicker red wire, then runs up the dash to somewhere behind the cluster, (it got dark before I could investigate further)
So wondering what this wire is all about, also curious if anyone has some ideas as to the battery drain. I have read tons and tons of threads about it, and they all seem to point in different directions. Most are pretty old by now, curious if there are any newer "more common" fixes. Could it be the Kessy? Am I just using wishful thinking? Perhaps something else? Odd that it would just now start being a battery drain issue after not working for 6 months.
Thoughts, suggestions, input? This vehicle has eaten up a lot of my free hours since buying it (trans valve body, air suspension repair, etc etc), but I knew what I was getting into, however this recent problem has me frustrated more than usual. Nothing worse than taking a car somewhere and not being sure if it will get you back home when you go to turn they key, then you have to do the "knock of shame" and ask for a jump.
