Using VAG Com, How to troubleshoot ABS Module and Speed Sensors?
My ABS light is on. How do I know if the ABS Module is bad. If it's the module.. I can do the soldering fix.
How would I find out which speed sensor is faulty? Do I just clean it? I read there were problems with clearance and distance.. How would you adjust distance? All I see is an allen head screw. Do I just have to loosen the bolt?

go into abs, log channel 001 ... that shows the speed sensors in km/h
drive slowly and look at the values. they should all match. if one is broken it will be obvious .. ie: 20kmh 20kmh 20kmh 3kmh
