Two problems related to fuel injection have been reported for the 1999 Volkswagen Passat. The most recently reported issues are listed below.
Our 1999 Passat with the 1. 8 liter engine stalls repeatedly when decelerating, this is dangerous. We purchased the car new and had a problems before 20,000 miles. Vw cannot diagnose this problem. I took vw to the bbb since they were very uncooperative in repairing this problem, and then they changed the throttle body. Then the problem went away for a few years and is now back and vw again refuses to replace the throttle body. The throttle body is obviously defective and they will not admit that there is a problem or fix it.
Intermittently when decelerating vehicle stalls out and dies. Prior to this problem, vehicle was at dealer for repairs,and vehicle was running fine.
