Four problems related to check engine light on have been reported for the 2019 Volkswagen GTI. The most recently reported issues are listed below.
16000 miles. Check engine light on and off. Purge vale replaced, two weeks later leak detection pump failed and needs replacement. Volkswagen claims leak detection pump is on national back-order with unknown time of arrival.
Vehicle intermittently will stall out when coming to a complete stop, and must be manually restarted for each failure and the car successfully restarts every time with no issues. Each stall happened while vehicle was coming to a stop between 0 and 10 miles per hour with no warning, with the clutch fully depressed and the vehicle in neutral. The vehicle does not have an auto start/stop feature. The failure seems to be either electrical or mechanical in nature, and only occurs when the vehicle is completely up to operating temperature. This stalling issue has occurred a total of 15 times in the week that I have owned it, starting with the first day of purchase, but does not happen every time I drive the car. There is currently no check engine light, and no codes stored for this failure. The engine does sometimes run very rough right before it stalls, but this has only happened 3 times out of the total 15 failures that have occurred. The only secondary issue that may be related to this failure is an incorrect gear indication being shown on the dash, which I have only noticed a couple of times. Currently waiting for service at the dealership to look at the vehicle, however, they have informed me that they are not aware of any permanent solutions to this issue and they are aware that this is a common issue with this year make and model of vehicle.
Vehicle stalls intermittently when coming to a stop. No check engine light.
While coming to a stop with the clutch depressed the engine cuts out. The engine has also cut out a few seconds after coming to a full stop with the clutch fully depressed. This has occurred multiple times, always while braking or immediately after braking while stationary. I am able to restart the car manually after this behavior. The car is new with 250 miles driven. The car does not register a check engine light or otherwise indicate any problem.
