[Vwdiesel] HELP! '01 Golf annoyingly persistent codes

[Dave Cook]

I presume that the washer light is simply turned on by a circuit being opened in the reservoir, either by a float or two prongs not making "contact" when the level drops.  (Never looked very closely at it.)

My guess is maybe the wires to that sensor are iffy; they have a bad connection.  The mechanic moving them around while cleaning made them connect briefly, but the vibrations in driving moved them again.

Check the connector to the sensor and the wiring harness for chafing.

For the ABS sensor, please make sure the sensor itself and the speed ring are all clean before replacing anything.  

Also, in my old Corrado, the front sensors both threw codes, but it was chafing/breaking in the (very expensive!) wiring harness.  I was able to repair it.  I went to Radio Shack and purchased a waterproof coaxial cable repair kit.  Worked like a charm, at least for several months until I sold the car.
