Since March we have a Leon ST FR 1.8l, the first months were great, but since the late summer the air conditioning smells really bad like electrosmog. Car was already twice to disinfect in the workshop, brought nothing at all: the smell was right after disinfecting again. As soon as the car is standing 30min or so it smells really strong at the beginning, after a few minutes it gets better. If it has stood longer it takes much longer until the smell is (almost) gone, a basic sound of stench is always in the air. Today after my wife left was a water puddle from the condensation water under the car (car was standing 1 day unmoved), the same stunk as what comes in from the ventilation. I always thought condensation does not smell at all… On the weekend I also noticed that coolant is missing and some liquid is collecting under the coolant tank. I then replenished (was 2cm under min) and removed all stains in the engine compartment. Ewish, since then you don’t actually see a bigger loss, but it drips a bit on the spot again, but where can I not find it. Does anyone have an idea what that might be? The smell from the climate comes when you just turn on the ignition, engine doesn’t have to run. Could there be a connection with the coolant loss? I always thought these are separate systems. Main concern at the moment: it’s the vehicle from the mommy and junior (2 years), what can smell there how not to be healthy. Maybe I imagine it, but I myself get headache from the smell. As an appendix an image of the re-forming stain, at the weld one sees the damp spot.
