[V8] VAG-COM question

[Buchholz, Steven]

... no BTDT on the Snap On stuff, but the 1990 V8 had the same
functionality as the 1991 ... 

Here again I have no clue on the Snap On interface, but I suspect that
it may provide all the functionality you need.  At one point you could
download the basic VAG-COM stuff for free ... if that is still true you
may be able to download the software just to see if it works with your
hardware.  

If you don't have the manual for the car you can get an idea of how the
VAG 1551/52 hooks up on the V8 from Scott Mockry's site
(www.sjmautotechnik.com).

As to available products, in addition to the VAG-COM product you can
read codes out of a V8 using ProDiag for the Palm Pilot.  

If you want to save the cost of the adapter, I posted the procedure for
integrating the OBD-II connector in the Audifans KB.
