Hello all,
I am a new Audi owner i love my car however i have to take it back the dealership where i got it from, long story short i have been hearing a squeaking noise when i turn the wheel to the left or make left hand turns but what is so weird is it only happens when it is hot outside or i guess when the car gets hot i live in Texas so the weather is so crazy out here but sunday it was hot near 80 and that my car was making that sound then today it is in the 50's and its not but i have to take it in today i dont want the guy to think i am crazy because now it isnt making that noise but i do want the problem taken care of. When i purchased the vehicle 3 weeks ago the left wheel was kind of wobbling so they replaced the wheel bushings. I havent a clue about any of this but i would appreciate some input thanks.
