I just bought a 1996 Audi A4, and for a good deal mind you, however there are little quirks that I am wondering about....... first of all, the driver sear doesn't move.... the electrical controls on the side don't work.... so, what I'm wondering is that something that is common in Audi's, or what could it be and how much am I looking to spend to fix it? Also, the check engine light is on..... is the A4 compatible with OBD2, or do I need a special diagnostic tool to check engine codes? Also, the front struts make a little noise while driving... the car has 90K miles on it, so I am thinking that it is just wear and tear and need to be replaced. How much do they go for? Sorry for all of the questions, but I just want to be sure of all of the little things. Any feedback would be greatly appreciated. Thank you.
