Two problems related to ignition module have been reported for the 1997 Volkswagen Jetta. The most recently reported issues are listed below.
Replaced ignition coil for the third time in as many years!! electric water pump replaced. Eater core exploded a couple months later while I was on the highway at 65 mph with my child in the car! couldn't see anything as car filled with antifreeze cloud. Belt driven water pump went a week later. Entire power steering rack needed to be replaced. Window regulator needed to be replaced twice. Door handle broke twice!.
Vehicle's transmission failed. The transmission had gone out when it was under warranty. It had taken three weeks to get the vehicle back at that time. The following year, the vehicle started to jerk. The vehicle was out of warranty. It wasn't until the vehicle stopped again, the consumer was told the transmission had leaked. There were numerous repairs. The vehicle was placed in the shop for the timing belt and the cylinder head. The vehicle also had to be taken in for a protective shield in the right rear wheel housing. The distributor cap, ignition rotor, and the spark plugs were replaced. Repair was also made to the wire for the ignition coil/cam shaft. The ignition switch was replaced and the engine control modules.
