Have an 05' A4. Today when my lights came on I got the beep and the message that my right rear light was out. I parked the car and went around to check and it was out (middle of the 3). Later in the day I started my car again and got the beep and the message the light was out. However the 3rd time today when I went out to my car, pressed the unlock on my key remote, I saw the light was working again and when I started my engine I didn't get the error message. The 4th time, same thing, working fine. Anyone think this is a sign that the light is gonna need to be replaced soon, or something electrical or some sensor going bad?

 

Bulb probably loose. Check it out, you need to do it from the inside of the trunk.

 

x2^ Check to make sure its snug in their.

 

Would I have to worry about a seal coming loose when I open the light up? I know with headlights, there are some seals to worry about as both of my headlights are fogged up from condensation.

 

The tails shouldnt be a concern. u should be able to just untwist the bulb from the housing.
