'03 A4 3.0L QUATTRO - ERROR CODES P0501 & P0741...ARE THESE RELATED?
 

Hi guys. I'm still new to the Audi scene and I've been trying to figure out how to narrow down my issue. I'm getting the P0501 - Vehicle Speed Sensor "A" Range/Performance, P0741 - Torque Converter Clutch Circuit Performance or Stuck Off...My ABS and "Triangle !" lights are on. I was wondering if these might be related. The issues I'm having are that my speedometer is not working, however it's still clocking mileage and all other gauges are working, but it will also not shift into overdrive. I have the 3.0L and I am having trouble finding specifics on whether my car has the crank speed sensor, transmission speed sensor, or if it's just one of my ABS sensors that are bad. Any help with this would be much appreciated! THANKS IN ADVANCE!

Don't think they are related. The VSS code and speedo not working are fairly common and are driving the ABS and triangle. That is either the ABS sensor that is mounted on your caliper or the ABS module itself. See this link for more info.

I don't have an auto, but the other fault would seem to be associated with shifting issues. Link to Ross tech page for the code.
