The rest of the story ....
The car worked fine for a day, then it went dead again.
I waited for the DME relay to come in the mail, hoping that was it, but it
I put in the new relay & the car stayed completely dead.
Got out the voltage meter and started testing again ... turns out the connector
on the end
of the wire leading to the fuse/relay box tested 12.9, but the terminal bolt &
at about 3 volts. The nut was tight, but a thin layer of corrosion had built up.
I must have bumped the wire enough to temporarily re-establish a connection when
the relay the first few times. Could have been sort of related to the brake work,
as the connector is near the fluid cap, may have bumped the wire or spilled a
bit of fluid
when working on the brakes. Got out my dremel and polished the terminal on the
end of the
wire and the bottom of the nut, put it back together, and works perfectly again.
have a spare DME relay in my toolkit in case it ever really fails ;-)
