VAG-COM

Issues

Possible Issues, all versions:

• SP1 (Sevice Pack 1) for Windows 2000 adversely affects VAG-COM's ability to do real-time and makes communications with some controllers unreliable.   The fix: install IE 5.5 (Version 5.50.4522.1800 or higher!)  over top of SP1.   Update:  SP2 and SP3 appear to fix this problem as well.
   
• VAG-COM's support for controllers using the new KWP2000 protocols is not 100% complete.  Examples of these controllers: Teves-60 ABS controllers in 2001+ Golf/Jetta/Beetle models and various controllers in 2002 cars.   The capabilities for Version 208.1 are shown on the VAG-COM Function Chart.

Car-Model Specific Issues:

Volkswagen:

• 2000-2001 Golf/GTI/Jetta/Beetle Airbags (important!)
• 1997 Passat B5 Central Convenience System
• 1990-1992 2.0 16V Engines
• 1990-1993 Cabrio/Cabriolet Airbags

Audi:

• Concert Radio & Symphony Radios
• 1992-1997 100/A6/S6 (instrument cluster)
• 1992-1994 2.6L V6 Engines

All: 

• 1993-1994 TDI Engines:  We have a number of reports indicating that VAG-COM doesn't work with these, but we think it should.   Since there were no TDI engines in North America until 1996,  we're can't just ask someone to borrow a car.  We did finally get an ECU in from Europe and hope to be able to resolve this incompatibility in the near future. 
  
  
• If when you try to connect to a control module, you get the error message "Can't Synch Baud Rate", go to the Options Screen and try setting the Start Baud to 9600.  If 9600 doesn't work, also try 4800 and 1200.    Turn the car's ignition OFF and back ON after each failed attempt to connect!
