I have a 2008 Cabrio with 80k miles. When you start the car the abs light and yellow triangle are on. When you roll forward at about 10-15 mph the lights go of for a few second. Then back on again. The codes point to right front wheel sensor. I replaced the wheel sensor. Still the same thing happens. I put the old sensor on my 2009 and it works fine. I check wiring to my abs module and it is fine. I think the module may be bad. Any thoughts?
