Have you checked the OEM website?
Description of Repair unable to perform
variant coding on PCM in 2003 VW Jetta engine code AVH. The variant code configures the PCM to the vehicle for options such as country, transmission type, and installed accessories. All other vehicles information that I checked on the OE website had the chart to make the correct variant coding in case the original PCM was not communicating except for this vehicle.
Description of Information not available
Description of steps taken to obtain information (help/contact function on website, websites, etc.)
Martin at Bentley publishers has been excellent to deal with and has tried repeatedly to get the information needed. I have talked to him several times helping him answer questions like what is a variant code, why is it needed. I have even provided examples from other vehicles of the charts to calculate the code. All of this information has been forwarded to VW and they can not come up with the answer to fix a car they designed and built!! This customer has been without a vehicle for 3 weeks now and time is of the essence. How long does it take VW to find information that is REQUIRED by law to be available for emissions compliance to install a new PCM?

Dear Mr. Layton, As a follow up to our phone conversation regarding the 2003 Passat. I understand that you are able to code ECMs using your own scan tool. I also understand that you have a method of re-setting the immobilizer after ECM replacement. The ECM was replaced due to flood damage and that the car is currently running and drivable. You will seek out a VW dealer who can hopefully code the ECM correctly. We have requested the coding document from the factory and will display it on Ebahn as soon as it is available. Thank you for your feedback. Best Regards Volkswagen Service Information Compliance
