Coolant system external leak was fixed, hoses replaced and connector that attaches to engine was replaced also. Leak comes back, replaced another hose., then the worse starts, the heater core started leaking and the car started to smell like antifreeze. Got heater core replaced, but the inside of the car smells horrible, .every time I drive my 1999 Jetta, I get this metallic taste in my mouth and throat. The stuff is definitely toxic, and the af container reads poisonous. Becomes a torture to drive my Jetta I hate the metallic taste in my mouth. The design off some of the heating system includes plastic components that may not take the heat well specially at the point of contact with the engine. Did some online research and found similar cases with internal antifreeze leaks on VW Jettas. This fumes can really ruin your driving experience not to mention the possible detriment on your health due to breathing in a contaminated atmosphere thanks for looking into this complaint.
Leak in cooling system causing migration to water pump, heater core, and engine wiring harness. Having to replace all 3. car stalls at random times in busy traffic, posing potential accident problem. Caused toxic fumes to come through heat vents in car.
The thermostat housing needed to be replaced due to coolant leakage. This part had to be replaced to prevent coolant loss. I had to purchase the part and pay to have it replaced.
Map failure. But also "coolant migration problem." Wherein, due to faulty coolant reservoir sensor seal, coolant migrated out of coolant reservoir and into wiring harness causing speedo and cruise control failures. Was repaired at no cost, as was maf. However numerous tdi and gasser owners are constantly reporting maf failures.
