1999 Volkswagen Jetta Q&A
1999 Volkswagen Jetta Question: 4000 rpm/80mph engine loud noises y?
Locating and diagnosing the cause of noises are difficult, trying to figure out what is wrong without seeing and hearing the problem first hand is near impossible. I would try to schedule an appointment at a repair shop and insist that you have someone go on a test drive with you so you can have them experience the noise. - lawrenceg
