Re: ur-quattro oil temperature problem


    Some cars have a voltage stabilizer built into the instrument panels to
ensure a constant voltage to the gauges and accurate readings. I've never
looked for it on my Audis, so I can't say it's there, but I would suspect it
is. It is sometimes built into one of the gauges. Perhaps the smoke has been
let out of yours.
