[. . . ] The Concerts have blatant bugs in the diagnostic protocols. We've added one work-around to the low level protocol drivers that works in some, but not all Concerts, and it is not 100% reliable in any case. Some Concerts occasionally get "stuck" in an undesirable mode after attempting communications. If your Concert gets "stuck", the way to reset it is to remove all power from the radio for at least 10-15 seconds. This can be done by: · · · Removing the radio from the car. Disconnecting the car's battery Pulling the fuse for the radio. Note: Some radios will require you to enter the "security code" using the radio's front panel after loosing power. See the owner's manual for the radio for instructions. It appears that I suspect there is something not quite up to snuff in the Symphony's ability to drive the K-line. We've had some reports that they work better with non-optically isolated interfaces, and they may work better with the engine running (which means there is a higher voltage on the VBatt lines in the car). 1992-1994 2. 6L V6 Engine (non-US only) VAG-COM cannot communicate with some of these ECU's while using a "dumb" Interface. These ECUs (made by Hella) are so incredibly fussy about the protocol timing that there is no way to get them to work with a "dumb" interface and an application running in user-mode under Windows. For vehicles with these engines, we recommend the HEX-COM or HEX-USB Interface, which work great. 1996-1997 Audi A6 2. 8L 12V V6 Engine There is a bug in the Hitachi ECU that does not allow reliable monitoring or logging of multiple measuring groups. For these vehicles, we recommend only viewing or logging one group at a time. 37 VAG-COM Appendix B: VAG-COM Frequently Asked Questions (FAQ) Q: Will VAG-COM work with my car?A: VAG-COM will work with most Volkswagen and Audi models sold World-Wide 1994 through 2004. It will work with some cars all the way back to model year 1990. It will also work with most late-model SEAT, and Skoda models sold in markets other than North America. If your VW or Audi has a 16-pin "OBD-II style" Data Link Connector, VAG-COM will definitely work. If your car has the old "2x2" Data Link Connection, check if there is a wire going to each pin, as shown in the picture. If there are four wires, VAG-COM should work. Please see these Application Charts where you can select your model and see which modules can communicate with VAG-COM. Also see the Issues page for a few things that may not work as expected. [. . . ] The "pause" button ( II ) can be handy to make screenshots of a particular situation, like a boost spike for example. 51 Appendix C: VAG-Scope cont. VAG-Scope ­ FAQ cont. : Q: VAG-Scope says "unexpected end of values". A: At this time, VAG-Scope does not support appended log files. More precisely, it will only read the first part of them. The solution is to give your files a more specific name than "LOG-001-003-xxx-xxx" :-) Q: "This is not an original VAG-COM log file" A: Guess what, you altered the file in some way. [. . . ]
