Hello! I had the following problem the day before yesterday. After I started the heater by FB, I went to the parking lot about 15 minutes later. At this time the exhaust fumes from the right fender smoke. After I examined the phanoomaun further I found that the exhaust of the heater is so close under the engine compartment (underfloor just behind the right front wheel) that the exhaust gases were sucked in again by the ventilation. When I opened the vehicle I found out that smoke fumes were already coming out of the ventilation in the interior. Since today my little one is at the . time what he finds out. However, it can not be normal that Abgsae can get into the interior. Could also be life-threatening once if you don’t notice it in time and sit in the car. Does any of you have similar problems?
