[Vwdiesel] Head lights 91 Jetta

[William J Toensing]

I am not an electrical expert but I do know this. Electrical components deteriorate over time. In Europe, any car over 10 years old is considered an old car. With these VW diesels, we are dealing with cars 15 to 30 years old, often with over 200,000 miles or more on them.  Connections become corroded including switches, which also become worn out from use. Because of the inability buy new diesels in "our so called free country", the USA, we are trying to keep going, cars that were never designed to last that long, although with proper preventive maintenance & repairs, cars can be kept running almost forever, baring being totaled in an accident. Therefore, cleaning connections including grounds, adding extra grounds, & use of relays can be useful in keeping these cars going beyond their intended life, when they were not necessary when new..
