Hey fellow members,

I had to tackle this door handle job trying to understand why my convenience switch was king of activating by itself.
Scanned module 46 Central convenience
Measuring blocks, 001 LF door, 007 RF, 008 & 009 the rears
if you 're looking at the 4th box in VAG COM it will say Not Activated or Not operational, when you press your button it will say Activated
My passenger door button was stuck on Activated all the time as if someone was holding it in non-stop.

To dissasemble the handle,
You need a
T20 torx bit
T5 for door handle bolts

Here's whats hiding under a black cover on front door, abou the door handle height



Keep unscrewing the T20 screw until you can easily move this piece and just pulling it outwards it should come out with a little bit of jiggling around



Now the door handle is a 3 piece affair, you will find tiny T5 screws at one extremity and the other, everything is sort of clipped toghether, apply gentle force evenly when trying to separate pieces, watch out not to be prying on a painted surface that is visible from outside



Now a little bit further into the dissassembly, i found my button and a tiny bit of moisture and probably corroded contacts on where it was sitting



I was very sorry to discover that the handle is not serviceable or parts cannot be replaced in it due to its one time design, and some kind of very hard sealant which is poured and solidified to supposedly keep all the electrics from the elements, however i think this is why they have such a high failure rate.



So all in all, decided to cutoff and isolate the wires going to this handle because as i was doing this dissasembly the VAG-COM was plugged in and monitoring inputs from the handle.
Even with the button completely unobstructed i would get the rather odd Activated state from time to time.
Unfortunately a replacement is the only option if you want this working, if not, well i can live without this on one or more door handles :cool:

Hey Hristo,
If you're Bulgarian so am I, hehe what a coincidence or maybe not that we like great cars such as the Touareg. Anyway if you want PM me, i will give you more details about the door handles, i've been driving with all 4 disconnected on my V10 for the last year. No issues whatsoever besides losing the convenience feature.

OK guys, I think i found the final piece of this puzzle.
The way to totally disable the auto unlock function is by unchecking it in the comfort menu of your MFD when vehicle running and not moving. You have to scroll down the option is found just under auto lock, take off the tick mark besides auto lock and auto unlock, so far my battery holds steady and all works as it should.

Yeah, do not cut any wires, there's a plug coupling for each handle which you will see when you remove the interior door card, just disconnecting it there should be enough.
Secondly make sure you disable the Auto Unlock function in the MFI display, this also plays a part, it is found in the convenience menu.

It's the harness coming through the window regulator at where i have circled in red, can't miss it

Also don't forget to turn off the AUTO UNLOCK function in your MFD, go to the comfort menu and door opening, scroll completely down and uncheck.

The correct way to check your current draw is this
1. use a screwdriver to latch your driver door closed, but leave it open, close all other stuff, hood, trunk all other doors
2. Lift up the driver seat to expose the battery
3.Disconnect the negative terminal and wire it through a DVOM with the ability to measure amp draw up to 10A.
4.Spec for current draw after 10 min when alarm is armed should be no greater than 60mA

Also, my door handle buttons were acting up, as if someone was pressing them, that alone wasn't the only culprit.
Found my wiper motor taking a lot of power, probably due to an improper park position of the wiper arms or something
