View Full Version : Do I need to reset anything?

12-06-2010, 07:33 PM
Hey guys, I just purchased a new abs control unit (pump and ecu). I have had the abs and brake light on for a while and finally got a good deal on a used one that fit my car. (99.5 a4 1.8t). When i swap out the bad ecu for the new one, do I have to reset any codes? Or clear codes or will it just magically make the lights disappear? TIA.

If you have an ABS and blinking brake light, just swap the ECU part and it will magically make the bad lights disappear.
