Audi A4 / S4 TSBs (Technical Service Bulletins)

Some things are often misunderstood about recalls and technical service bulletins (TSBs). Plus a disclaimer.

  1. Recalls do not have to be issued only because something is prone to failure. NHTSA (a government agency) can only require a recall if a failure will affect safety, emissions, fuel economy, or compliance with some other regulation or law. Manufacturers can voluntarily recall cars for problems that do not affect these, though.
  2. Recalls often apply to only some cars of a specific model year, rather than all of them. You should receive a letter from the manufacturer if your car has been recalled. You can also check with the dealer, which will know which (if any) recalls pertain to your car.
  3. The primary purpose of TSBs is to inform dealers about known problems with a car and how to fix them. They are not the same as recalls. As with recalls, TSBs often only apply to some cars, not the entire model year.
  4. Dealers often will not provide a preventive repair just because a problem described in a TSB might happen to your car. They'll usually want to observe symptoms that the problem is already affecting your car.
  5. Even if there are symptoms, a manufacturer doesn't have to pick up the cost of a TSB repair if the car is out of warranty, though sometimes they do.

We provide the text of recalls and TSBs as provided by NHTSA. There can be errors in the text. If you sign up for notifications in My Garage, we will try to get these to do, but for various reasons (some beyond our control) cannot guarantee you will receive them. When in doubt about a recall or TSB, contact the dealer.
