Car lost battery voltage and now remotes don't work. I am using Wiki video procedure to Pair/Synchronize the Remote key on 2 different cars. Unable to save adaptation values for channel 21 Comfort Module (46). Tried both VCDS mobile and VCDS via browser on laptop. All the steps work until you are supposed to press the remote button after putting in a new remote location value. At this point you are supposed to click the remote button and Field 3 should change from Adjustment to Recognized. Nothing happens. If I click save and re-read Channel 21, I get the original un-synched values of "0" and "Adjustment".

It might be useful if you told us exactly what kind of car you're working on there. ;)

While looking at measuring values group 007 in your comfort module, press various buttons on the remote. Does anything change?

Yes. For each button on the remote it displays 1,2 or 3 depending on lock, unlock and trunk.

Yes I tried the special procedure. No response from the locks or lights.

What exactly happened originally when you said, "Car lost battery voltage" ?

I'm thinking the next thing I would try is to cold-boot the comfort module. That means removing all power from it for a while, either by disconnecting it from the car's harness, pulling the appropriate fuses, or disconnecting the car's battery for a while.

Cold reboot done. No change. I am thinking this has to be something in the scan tool software. I will try a different scan tool on one of the cars. I will post the results.

Mac, did Andy talk you through doing a "Feature Update" today and is your HEX-NET working correctly with VCDS yet?

Hex Net is working via Mobile VCDS and VCDS beta application on the laptop is not working, I am only able to access the Hex Net via a browser. I will try the feature update tomorrow. I used another scan tool and the key remote synced right away. There is definitely something with the software coding that needs to be looked at. Let me know what additional information I can provide to help resolve this glitch, I have another vehicle I can test and program.

OK, thanks for the (apparent) bug report.

Just to close the loop on one portion of this, Mac reported that the problem of not being able to use VCDS Beta with his HEX-NET has been fixed. We will try to reproduce the remote matching behavior soon.
