Audi A6 TSBs
The A6 has been assigned 2,182 technical service bulletins (TSB). The 2013 model year has been involved in the most bulletins.
TSBs contain recommended steps and procedures for diagnosing or repairing a known problem. They are issued directly by Audi to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
