Dear dot, I've a 1998 audi a6 quattro. My ABS system shows warning yellow ABS light and red flashing brake light at all time. I've taken my two shops and they both indicated that the ABS unit is defective and needs replacement. They tested all 4 wheel sensors on the car and also mapped out the electrical system. The conclusion was a defective ABS unit. I've done some research and other audi owner from 1998 - 2001 also have the same issues. If this system is known to be defective, it should be recalled in all fairness. I am pretty happy with this car, but the ABS is an uncomfortable experience. It cost about $2000 to replace the ABS unit and audi does not want to admit the problem.

What 1998 Audi A6 owners say
Most recent owner complaints, unedited.
Abs/brake light on all the time. I got my brakes changed, my mechanic checked it, and told me the ABS system is malfunctioning.
1998 audi a6 with 130,000 miles; ABS/brake lights on dash illuminate with piercing tones, first intermittently, now upon startup and drive off. Manual states this is an emergency situation, and driver could possibly lose control of vehicle. Dealer states repairs $1500.00+ for complete ABS replacement...audi owner forums include many others with identical problems...no other repair options were offered by the dealer.
Antilock brake system (ABS) control module is apparently failing or has failed. Both the ABS and brake lights on the dashboard illuminate irregularly accompanied by three loud warning tones. Both lights likewise turn off without warning. Dealer claims that no code is being returned from ABS unit. Advised that sometimes ABS will be available and sometimes not. Cost to replace ABS control module was quoted at $2,400. Advised to ignore warning lights and sounds if cost was unreasonable.
The ABS braking light appeared on the dashboard and remained on. Driver noticed that while applying the brakes the pedal went to floor, slowing down and then stopping. Driver took vehicle to the dealer, and the mechanic placed the vehicle on a diagnostic machine, and determined that the ABS control unit module needed to be replaced.
I have a problem with the ABS light that comes on often.is too expensive to pay for all this .can somebody do somethng about . Thanks.
Abs computer malfunctioned. Searched internet and found many similar problems with other owners of simiilar cars.
The vehicle's ABS controller failed after less than 70000 miles. *nm the consumer requested assistance from the manufacturer but was denied.
I own a 1998 audi a6. This vehicle has been driven approx 75 000 miles. Several months ago the ABS control unit (brakes) failed. I was quoted a price of $1085 by the dealership where I purchased the vehicle. There are no used parts available. When I made an appoitment to have the unit replaced I was informed that audi no longer manufactures the origional replacement part at a cost of $1085. Rather, audi has remanufactured the replacement part and the new cost is approx $2000.00. I verified the cost of the remanufactured replacement part by calling a few dealerships. My complaint is that I believe that audi recognized that the original part was defective and that once the ABS control unit failed it made ABS braking inoperable and therefore unsafe. Rather than recall the 1998 a6 to replace the defective ABS control unit, they allowed consumers to either drive with an unsafe control unit that could fail at any time ot pay almost $2000 to replace the defective part.
Intermittent ABS/brake light 1998 audi a6 quattro 2.8l, audi dealer says it has faulty ABS module which would need to be replaced. Cost: $2,148.00 plus labor. Nothing was done to correct the failure. Dealer says it is a common problem.
