Brake Antilock Wheel Speed Sensor Problems of Volkswagen GTI

Tl the contact owns a 2009 Volkswagen Gti. The contact stated that the abs brake module malfunctioned. Several years ago, the vehicle was taken to be repaired per NHTSA campaign number: 16v913000 (power train) by heritage Volkswagen parkville (9215 harford rd, parkville, MD 21234, (877) 398-1963). After a couple of days, the dealer refused to perform the recall repairs because the vehicle was showing the incorrect failure codes. The contact received a second recall notice in the mail and was informed by the dealer that the vehicle would be repaired. The contact stated that the brakes started grinding and twitching and the entire instrument panel illuminated. In addition, the speedometer stopped working, the steering became loose, and the vehicle stopped accelerating after the accelerator pedal was initially depressed. The vehicle was taken back to the same dealer and they stated that the repairs would be covered; however, they later called the contact back stating the recall repairs would not be covered. The incorrect failure codes were vag00290 (driver's side rear abs wheel speed sensor with mechanical function) and vag00285 (passenger side front abs speed sensor). The contact stated that she received a letter from the dealer that the recall had to match two of the specific codes, which was why the recall repairs were not performed. The contact was instructed to call the manufacturer. The manufacturer was contacted and stated that they would contact the dealer. The contact received the run around for a week with both the dealer and manufacturer, stating they were waiting to hear from each other. Recently, the contact was informed that the recall repairs would not be performed and the contact made arrangements to have the vehicle repaired by an independent mechanic. The failure mileage was 110,000.

Car started to exhibit intermittent abs faults which was indicated by dash mil and the following fault codes: transmission module 18255 - please check dtc memory of abs controller abs brakes 00290 - abs wheel speed sensor; rear left (g46) 012 - electrical fault in circuit - intermittent 00290 - abs wheel speed sensor; rear left (g46) 008 - implausible signal - intermittent with the codes present both abs and electronic stability control are disabled. The safety complaint however is that the automatic transmission control is periodically locked out. When at speed (60+ mph) the automatic transmission will shift into neutral. Manual gear select will not put the car back into a drive gear. Dash gear indicator will indicate 6th gear. At lower speeds (~25 mph) the transmission will periodically lock in second gear and will not shift to a higher gear. Manual gear selection also fails. Problem sometimes will not clear despite restarting the car multiple times. There are no indications of an actual transmission problem. The cause seems to be software override of the transmission due to incorrect abs module data. (transmission software seems to think the car is in a skid and is holding gear). So far the abs module,wheel speed sensor, and tone ring have been replaced. Condition is still present. When the transmission problem is present shift lock also does not work. The dealer is currently in the process of replacing the wiring harnesses.
