Hi, go to vag-com main screen, press select, click on the central conv. and note the faults. If it does not work scan central locks. If its still does not work go to the dealer next year ! I suggest changing(lowering) the baud rate. See the vag-com owner manual thet can be downloaded from rosstech site in PDF format and read it, as its explains how to do it, in detail ! Only somme aftermarket radios can blow the K line so you safe there !

Thanks It says above that I tried that to no avail and that a dealer is out of the question.
I can scan the abs radio and engine controllers but I get a NO RESPONSE FROM CONTROLLER from all the rest
I tried 2 laptops to get the same message and Im using a cable from e bay on com port 1 usb

I will look up changing the baud rate and give it a bash later and have a look for wiring breaks.
If anybody could post a link to a site discussing the loom break I would be greatfull

Then the CCM module is toasted so thats why you dont get no response from it ! Check under the carpet in the front footwell and see if the controler/module is corroded due to damp from the bulkhead drains. Its ok to get another one from ebay, but it will need codding. If you can scan yours after a good clean, note the codding- 5 digits number and input it into the new controller so the unit will work as should in your car. If you cannot read the controler, google openobd for details on how to code the ccm or you can get someone with the same car from a similar engine and same part nr. and you could copy their codding nr. It may not work 100% as beffore but after you read tdiforum.com you should understand what i am talking about. After you code module you could select more optional features, but you will need the registered version of vag com ! Hope this helps.
