I have a 2003 Audi A4 with 37,000 miles the turn signal sensor light came on saying that the turn signal wasn't working. The turn signal will work then will stop then work again. Help!

 

prolly a bad bulb

 

Could be a bulb or a bad connection. Maybe something else. When I turn the right signal on my car, before the click(blinks three times then stops) its fine, if I fully engage the right turn signal it blinks the left a couple of times first and then blinks the right and even after the switch has returned to the rest position it continues to blink 1-5 times. Anybody have any possible fixes for that? I have the bentley manual and can not find a relay it must be in the ecu? I would think switch but it doesn't seem likely to me. Would a (ross-tech)Vag-Com pick it up?
