I bought a 2005 Audi TT Quattro, which I love. I had to change the battery and the radio went into "Safe" mode so I need the 4 digit code, which only the dealership can provide. They quoted me $190 to remove the radio in order to get the serial No. I looked it up, bought a tool for $8, and removed it myself within a couple minutes. Now they insist that I bring my car in so they can hook it up to a diagnostic machine and get the code that way and are going to charge me $190. They created an unnecessary procedure just to charge $190. I knew I would pay more for service when I needed it but this is like extortion. Audi treats it's customers like $#*!!
