ABS module failed at 89,000 miles. Pulled ABS module apart and found one hair fine wire separated from the circuit board. Made the repair myself, not for the beginner but doable with some skill. Step by step technique is posted on internet. Total cost about 2.5 hours of my time.

module failed: replaced with new :Expensive!!, then had to take to the dealer to have it activated. more $$
When the ABS controller malfunctioned, it also caused many of the control panel controls to fail, including the tach, oil light, and others. A new controller fixed the problem. The dealer wanted $750, but did it for $500

ABS Light flashing and Brake Warning Light on steady with three warning beeps after turning on key.
"Communication Failure" mechanic says after a lot of testing.
Seems to be a universal problem on VW Passat of this vintage, but still no recall.
