Four problems related to engine and engine cooling have been reported for the 1999 Volkswagen Jetta. The most recently reported issues are listed below.
The vw vehicle is programmed to cripple the engine performance and speed in case of an epc fault. Any fault causing a rich or lean condition will cause this "limp mode". This is a safety issue especially people on the highway going 65-75mph and a 80,000 pound tractor trailer behind them as one person experienced. There are too many non-vital component failures to list that can cause this fault. I refer to non-vital meaning the component failure will not harm the driver of the car. The fault light indication isn't enough? now they have the right to force you into a repair shop and buy more vw parts. I feel that this is a money making scam endangering our lives. We do not put a halt on this now- soon any fault will cripple our cars. It's not just vw (Hyundai did a similar "limp mode").
About every 2,000 miles, the engine in my 1999 mk iv Volkswagen Jetta starts ticking, and I check my oil, and im a quart low. Everytime. The engine quality is steadily declining. I have not done anything to repair this because I do not have the money, nor do I trust mechanics with the car.
For the second time the consumer had to replace cracked and broken engine mount on vehicle. The consumer is unaware of way it keeps occurring. Dealer notified.
