I installed the driver front wheel speed sensor tonight. Took the car for a quick ride and after doing a reset, the light will stay out for about 20/30 seconds and then illuminates. Guess that is progress since it was on continuously even after a steering wheel reset before changing the sensor.. Spoiler did not seem to react to the new sensor either, since it did not work automatically. Hope to change the passenger front tomorrow. We will see if there is any further improvements. Have not had the codes read, Guess that should be the next step. My reader won't scan the secondary modules.
