    W163 Heater Problem

    I have a problem with my ML270 heater. It seems to work well then when I go round a roundabout I lose my heat and have to build it up again. Feels to me like a big air lock somewhere in the system so how do I go about bleeding it. Diagrams and location of heater hoses would be appreciated.
