Porsche 911 TSBs
The 911 has been assigned 220 technical service bulletins (TSB). The 2018 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 Porsche to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
