Hello everyone, to my debut I just come with a problem: My Cougar 2.5V6 Bj 99 makes a loud “wowing” noise lately after a cold start. I thought first I need new wheel bearings, but it also makes it stand in. If the engine is warm, the noise is gone. In addition, the fuel consumption has increased extremely since: if I normally consume 10.5-11.5 liters, I need now more than 13.5 liters. Gruesse bu508a
