Hello, As a result of the long-running foggy windows in a VW Passat with Klimatronic, I was at my car dealership and it was found that the heat exchanger is leaking, and coolant has been getting into the interior of the vehicle for weeks through the ventilation. My Passat is 5 years old and has 84,000 km down and I drive to work with it every day. At the same time, I have had a strong, ignited eye irritation and a strong flu that does not want to fade away. The complaints I see in connection with the coolant in the vehicle. I plan to go to a doctor and examine my blood on traces of this coolant ! What prospects would a lawsuit against the manufacturer have regarding product liability . Who has already done this ? What can this mean in D for a financial compensation ? I am grateful for suggestions ! Thanks in advance & greetings !
