My abs light started blinking in my 1998 Audi A4. I went to a mechanic and had it diagnosed; found that it was a light failure; I was told I would have to pay a lot of money to pull out the electronics and most likely not even solve the problem. Later I started to notice that my abs was not engaging properly and sometimes not at all (which is now the case), I filed complaints with Audi and boshe about this but they told me there could be no recall because abs is not a traffic concern. Recently I was driving in the rain and making a 98 degree turn not terribly fast; there was no stop sign, and I ended up doing a 360 to a stop. I found this not only a scary experience, but one that could have been life threatening. It didn't make sense; im driving the honorable quattro. I decided to look further. I found many people have the same problem. Specifically w/ models in 1998. Im a fairly good driver in fact I did a defensive driving class at infineon raceway so I was still confused how I lost so much traction in such a short amount of time. I found the problem was actually part of the quattro itself. The electronic braking, traction systems, and various other vehicle dynamic systems are all dependent on the abs control module. All the test up to then showed no link to abs control unit; I was made to believe that my car just had a light failure. I started researching the control unit and I found that there is already a recall on the part but not for Audi but for Volkswagen! the campaign id number is 02v031000. I talked to people who were owners of volkswagens who got the recall and many of them had almost identical problems to mine. Some even said the unit caught fire. So here I am told I have a light problem, then told Audi cant do anything for me except get a whole new abs system at my expense. Now I find the truth is one control module is responsible for the lack of control in my car as well as a possible car fire. Please help: I and many others need a new unit.

I own a 1999 Audi A4 with approximately 74,000 miles. Recently upon start-up the abs indicator light comes on and the brake indicator light flashes. I have taken the car in for service and have been informed that I no longer have anti-lock brakes and that to remedy the situation will cost in excess of $1500. This is completely unacceptable and appears to be due to a Audi manufacturing defect (anecdotally, I have heard of hundreds of similar issues with the abs). While the car is operable using standard brakes I believe it is a significant danger should the abs be required. Please look into this issue.

Audi A4 2000 1. 8t (1) abs light flashing. Brought to dealer. Quoted $600 for repair kit, $1500 for new module. Both prices do not include labor. Searched internet and hundreds of other Audi A4 owners have experienced the same issue. (2) abs is now intermittent on my car and warning light is on constantly. (3) can't correct right away b/c my Audi dealership is 6 months back ordered. I assume because so many owners are experiencing the same problem.
