I just replaced the front pads and the car is pulling to the left, is this a minor alignment problem or did I do something wrong on the installation? The brake pad light is no longer on however so I hope that is a good sign.

 

If you only have the pull when braking, then it ia an audi brakes pull. In this case If it pulls to the left when braking, the right disc brake caliper is probably not working properly. I think it's safe to say that if you replace both front calipers the problem will be cured.
