Re: 156 V6 Diagnostic....
Mason145, Try a search of forum threads for diagnostic or examiner and such like - I found loads of stuff when looking into one for my '99 156.
Fortunately I'm ok with Alfadiag, but I think yours is an OSDB II (?) system, which is more generic so maybe easier to get s/ware for?
If your bro gets alfadiag, he'll need an RS232 port to connect to, or a USB to RS232 emulator lead - got mine from ECUfix, again other threads cover this.
One point to note was that the default "interface timeout" settings should be increased, otherwise frequent disconnection of the software from the car occurs - very frustrating! Derek who wrote / supplies alfa diag was very helpful and said himself the timeouts were aggressive - he may have done an update to alter them by now.
Good luck with your search.
