Hello, I drive an Audi 80 Coupe, 5 cylinders, BJ. 86. I had a used KAT installed for the TÜV this year, because the other one was probably empty cleared.! Last night I was traveling home with my Audi and he ran worse and worse. He had detonators and ran at last only 40 kmH. I drove him with the last force to our front door. As I got out I only saw that it smelled everywhere and very burned. Under the car glowed from cat to rear silencer a lles. Over the axle it has ignited and it has started to burn. We could delete this with water after some time again. Then you could see that in the trunk already the tub was sunk and already melted away where behind the tank is. Where still about 20 liters of reserve was in the tank. Then it was still a while ago and then laid down. I had of course on the other end of the phone already the fire department because I thought that this also to the ex plosion can lead. Well, all night no eye to get.! Has anyone ever had such a thing .? Please for answers and tips.! Greetings Nicole
