    I've been looking into diagnostic scan tools for the 1997 S8 with AHC on my drive. Being a '97 it's a little unclear exactly which scan tool I need. The OBD-II port is confusing as it has wires out of 1,4,5,7 & 16. Which is just weird.

    Steve all scan tools will hunt out the correct protocol being used at the plug, so no need to worry about the wiring order, the scanner will find the match.

    EDIT: If it helps pin 4 is chassis ground, 5 is signal ground, 16 is power and pin 7 is the SIL (serial input line) protocol ISO9141-2

    Right you are. I think I was getting confused with CAN BUS systems.

    Or maybe not. Got a U280 (most common eBay scanner), plugged it in and nothing, just sits there saying 'scan...' trying to get some sence out of the seller, but no joy so far.

    Reading some conflicting stuff on the net. Anyone know what the red line and rev limit is with these? Do they vary across the slightly different models AHC/ABZ etc?

    Does depend on age and variant. The RS-4 (414hp) heads upto 8250 while PW's one is 7k i think.

    There used to be a website called rsmodels.net that had them all listed, can't seem to find it now :(

    Just to follow up on this, the heatshield around the exhaust has dissolved and a bunch of the OBD socket wires had been melted together, U280 does work now it's been rewired.
