Touraeg Can Gateway 19 not working

Hi
I have just bought a 2008 toureg V10 with a few problems one of them current draw on the aux battery that for some reason the battery management wants to start from,.
Even when the starter battery is 12v+ and the aux is 11v.

I have done a few auto scans and saved them but unfortunatly away at work and cannot share them.

In the scans there were some com's errors.

I selected Can Gateway 19 and went to click on adaptation to try and see what the battery managment system entered as far as batterys ( both batterys have been changed
prior to me buying the car and do not have BEM codes)

The adaptation box was darker and did not open when clicked on.

Then while moving the computer around, I have accidently clicked on one of the coding boxes above so I just shut the window.

Now Can Gateway 19 will not open and I cannot auto scan.

I can still look at the engine controller etc and the car starts.

Could I have caused this just from just opening and closing one of the coding windows?

Any Help would be appreciated as I am just finding my way with VW's and VAG com.

I just want some hints in how to get this Can Gateway up and running so I can start looking into these problems.

Your time and knowlage will be greatly appreciated!

Need scan data and yes altering coding can indeed cause issues but there were also problems with gateways for parasites on those old V10 PD + water canoe piles.

+ controllers like to take on water 0x01, 0x11, 0x05, 0x17, 0x56, etc....

Truck should of included bucket and snorkel!

Get the data and post it please.

BTW, there has been false info out there. Rear battery is definitely responsible for glows and starter. You can log voltage drop in MVB’s. Any momentary dip below about 9.5v will throw codes.

If you haven’t yet removed the plenum drain bladder valves, do it. The address 11 ecu may have taken a bath in the plenum.
