Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Volkswagen Jetta Owner Comments

Jetta 4-cyl Diesel

  • Manual transmission
  • 108,841 miles


I have a 2003 Volkswagen Jetta tdi gls. I should note that this vehicle has been faithfully serviced by the dealer following the maintenance schedule listed in the user manual. The vehicle currently has 109,000 miles. While driving the vehicle a few days before the incident date listed on this complaint, the A/C ceased to function properly. There was no cool air coming out of the vents. Also, when the vehicle was shutdown, the radiator fans would continue to run upwards of 15 minutes. Neither event has occurred before. I brought my vehicle in to a VW dealership on the incident date to have its normal 110,000 mile service and to have the issues (noted above) diagnosed. I received a call from the dealership later in the day on the incident date stating that a failure in the coolant level sensor caused coolant fluid to be wicked into the vehicle's wiring harness leading to contamination / corrosion of the engine and body harness. The quote to repair was approximately $6,000. This problem is a latent defect in the design. The service department told me that the vehicle was un-drivable until the repairs are made. The service advisor also confirmed that because the problem was with the harness itself, any electrical component could be affected such as the airbags, ABS, SRS, etc. Also, from my own research I found some people who experienced this problem have also had smoke or fires inside the vehicle. VW issued a technical service bulletin (id# C 97-01-01) for a similar issue on 1999.5 - 2001 model year Jettas, but never for the 2003 and never a recall campaign on the defective design. VW has refused to assist in the cost of repair to the vehicle as well.
