Canada and Mexico users register by providing only country and zip code. The state list is static and contains only the US states. Therefore it should be left empty. The Canada zip code has the following pattern: A1A 1A1 where A is (nearly) any letter and 1 is any number. Don’t forget the space
between third and fourth character.

There are instructions on the home page under the “reprogramming” heading.

Yes a blue streak will work for certain model years. Please read the information on reprogramming on the home page.

Yes you may be able to do some 2009s with the on-line software. This program requires registration. Please read the instructions under reprogramming on the home page.

20. Can a 2001 VW beetle can be reprogrammed using this site with the Snap-On j2534...we installed a used ECM and the vehicle starts and stalls due to the immobilizer system.
For that model you would need a factory scan tool to reset the immobilizer. The pass thru application started in 2005 model.

25. I have registered and have paid three separate times ($35.00). It still wants to me to purchase a subscription again and I still cannot get the info after doing so two additional times now.

I believe it is your credit card blocking the transactions. This sometimes happens. Credit card issuers look at off shore purchases (Germany) as a security risk. AMEX does this routinely. We suggest you contact your credit card provider.

26. My subscription ran out and I need to renew. I am a certified Audi repair shop and this service is included in my fees.
(Apply 1100 credits to user’s account) You now have credit. Just select a one year subscription and the credit will be applied.

You can run it on any computer but they can only access it one at a time. There are no multi user subscriptions.

28. I’ve ready bought a VAS subscription but we cannot use it because it tells me you don’t have a valid subscription license.
The reprogramming system requires registration and security IDs needed to access a secure server. You can read the instructions on the home page under Reprogramming.

29. I am interested in getting service information for late model VW and Audi cars. It appears you are subscription based. Is a subscription for all VW and Audi Available or by individual cars or?
The subscriptions are separate for VW and Audi. The cost is $35 /day, $250/ month and $1500 a year. A subscription gives you access to all Service Information for all cars at least 15 years back some further, to 1996.

If you are using Firefox there is a known issue. (Send procedure to IRF or ask them to switch to explorer.
