    Brake Light Issue

    Guest-only advertisement. Register or Log In now!
    I started getting intermittent bulb out errors with my car a few weeks back and finally got around to get my HEXCAN cable to see what what was wrong with my car. At first I thought it was the bulb but I realized that when I go to unlock my car the bulb actually comes on but when I turn on my taillights or use my brakes the bulb doesn't come on and I get an error.


    I also replaced the bulb a couple of months ago, I wasn't sure if there is something I needed to reset within the VCDS settings.

    Here is what I scanned from my car.

    I found a thread for the S6 that many have found a grounding issue with their tail lights which I thought was my issue but if this is a grounding issue the bulb shouldn't come on at all which wouldn't be the case because the bulb is still coming on when I unlock my car.

    I wasn't sure if anyone has had anything like this happen, I tried finding something more A4 related but most issues are in other models.

    Thank you.
