2003 Quattro tiptronic v6 3.0
Error codes p0 501 vehicle speed sensor check engine light on, abs & esp lights on, headlight range control light on also, speedometer does not work.

I have changed the speed sensor (one located in the transmission) cleared code, light went off and speedometer worked again. Now the light is on and speedo does not work. Remember reading somewhere that this might be a problem with the ECU. Anyone have this problem?
