I have a 1999 Audi A4 Quattro 1.8 and I have run into an issue with the tail lights and signal lights.

The signals work intermitently, often times they have to be done just by manually moving the control. I understand there is a relay problem with this model car related to that.

Recently the signal light will come on in the rear - but doesn't blink - without the signal being engaged. It only seems to happen on one side (the driver's side), but I'm tired of being pulled over for a missing taillight, as that is what it looks like. Its also an intermittent happening. Could this problem be related to that signal relay issue?
