    Default Audi A4 B7, 1.8T. Leaking part identification. Bypass valve? – 25-02-2017,01:58 PM
    Hello. I have noticed a potential leak in the front of the engine in my Audi A4 B7, 1.8T. Please have a look on the photo. The bottom of the car under the engine, under the part I marked on the photo seems to be oil wet. Can you please help me identify this element marked on the photo? This is where the oil comes from I think. Is it a bypass valve? Is this serious? Please advise. Many thanks.

    it looks like a sweat more than a leak

    it could be the clamps, maybe replace them with jubilee clips will cure it

    Looks like the pipe coming from the diverter valve. it looks to have the factory clamps on it so I doubt it's leaking. More than likely the oil has come from a leaking cam cover gasket at some point in the past.
