As said above my ABS and Traction Control lights came off after i got a stage ECU upgrade. I was wondering if that is the cause of the lights. it would seem that the ECU is because there were no lights on before. Anyone have any other Ideas what the culprits are.

 

you have TCS on your car? didnt know any B5's had it lol

 

Yeah, I have the ESP button. but the traction control light is on. So Audi probably does what many car companys do and make a standard cluster for every model of the car.

 

My ABS and traction control lights are on due to a butchered ABS sensor on my drivers side. Have you played with that recently? I must have pushed mine in too far and it got chewed up.

 

So I finally got it looked at the ECU is no longer reading two wheel speed sensors.We couldn't find WHich one Since I had work that morning. but WE think that will clear it up. I hope...
