    B5 Garage
    My new to me B5 Passat 1.8t is having some issues. The first drive of the morning the car takes FOREVER to reach the 190° mark on the coolant temp gauge. After it reaches that point it’ll stay there for a few minutes and then start dropping back down. The heat also blows “warm” but not by any...

    Volkswagen Passat B6 Discussion
    Hi all, am o correct in thinking this is likely a flap motor fault? 2006 3c. If I crank the heat it blows hot on both, but turning down to low gets kind of room temp from the left, icy cold from the right
