Trying to help a friend figure out what’s going on with her 2014 Jetta S.
Here’s the situation in her words:
“Epc and traction control light come on randomly. While driving it’ll go between the epc/traction control to the abs light and brake light. If the abs/brake light comes on, it’s harder to get the car to accelerate. Steering wheel gets slightly harder to turn when abs/brake lights are on and Doors lock/unlock constantly when abs/brake lights are on.”
“The other night, the lights lighting up the numbers turned off while driving and turn signal wouldn’t work. Lights would go off and come back on randomly. Didn’t affect the headlights at all. Just turn signals.”
Had her get a new battery since hers was very old. Didn’t help. Told her to reset the computer. Read some cases with similar circumstances that were bad ecm relay fuse and have been trying to figure out its location.
Thoughts?
