Just do a search for VDU/VDC and you'll get a a bunch of hits describing the details. I believe tube has videos on how to re-solder. Good luck

I have almost the same problem. But even when the gauge drops to zero and the buzzer goes off, the brakes don't engage at all. I've had it in for service but they couldn't duplicate the problem because it generally doesn't occur till I've driven at least 80 to 100 miles. I was told there was no "real" problem and that it might just be a loose wire behind the dash. Also, it's only the left gauge that has that issue.
Thanks for the tip, I'll check the VDU/VDC as soon as I'm able.
