Volkswagen Jetta TSBs

The Jetta has been assigned 2,100 TSBs over 35 model years.
TSBs contain recommended steps and procedures for diagnosing or repairing a known problem. They are issued directly by Volkswagen to service technicians. You'll often see TSBs used as evidence in lawsuits when owners feel the automaker should help with repairs.
A TSB can cover multiple models and years. The 2014 Jetta has been involved in the most campaigns with 832 total service bulletins.
