Volkswagen Passat Problem

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.
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 and warning light illuminated. No solution found. Replaced both ABS front wheel sensors but ABS unit was the final straw as I had a new car on order.
