STG 46: No Response? Troubleshooting Guide.

Hello, I'm quite new to this forum...

I'm having a problem with my Golf 4, 1.9 TDI. I programmed the auto-lock function in module 46. Unfortunately, I've discovered that module 46 can no longer be found.
Das wundert mich da ich es ja mal erreicht hatte. Habe im STG 46 Kanal 04 aktiviert. Go for it! / Go ahead!

Only I can't find it anymore.

It would be really nice if someone could help me!

Hello,

Here are some things that come to mind spontaneously:
- The diagnostic cable uses a USB to RS232 interface adapter. -> It does not function reliably.
- Program settings in VAG-COM have been temporarily modified.
- The STG46 device has frozen; try disconnecting the battery and waiting a while. Be careful not to lose any radio codes or other settings.

Best regards, Rainer.

I've noticed this in the scan:

Quote:

1 Error found: 01336 - Corporate Data Bus Comfort. 80-10 - in single-wire operation - Disconnected

and 46 has something to do with the comfort bus .

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Hello,


Okay, thanks. I'll try disconnecting the battery and see what happens.

I have experienced this problem multiple times before.

Disconnecting the battery can help.


Have you added or modified anything else to the car (regarding the single-wire operation of the CAN bus)?

Good morning.

I just had the service done recently (STG 17). I'm going to try it out right away now.

Everything's fine now, I disconnected the battery and everything is working properly.

And of course, many thanks to everyone!


Thank you.
