I#m still searching for a scanner to read the diagnostic codes out of the 91 90 Quattro
20V.  What does everyone do,  just give the dealer the flat rate 70 bucks to do
computer diagnostics.  This car doesn#t have a maintenance indicator light so if you
suspect something is wrong with engine management you take a shot(s) in the dark or
go to the dealer to who tells you nothing is wrong or it#s an intermittent fault.  Is the
interface the SAE j1850 serial bus.  Searching the diy-efi list archive didn#t do much
good either.
