RE: HELP! - Fault Codes

["Duff, Ian" <iduff@charter.com>]

Climate control codes are for climate control and associated junk (used
advisedly) only. Engine CPU are not part of this function.

Not sure how to get ECU codes, but Bentley decodes them. ECU codes have
something to do with a fuse in the fuel relay, then count
flashes/pauses/flashes, remove/wait/install fuse, repeat counting
flashes, I think (really, I do). YMMV. It would be supremely excellent
if the procedure were in the Bentley, but it wants you to use a VAG tool
to capture them.
