M 400 oil & water leak

[kenprotheroe]

Recently seen, a very slight oil & water seepage,

externally and down from the bottom of the driver's

side air pod that houses the oil-cooler.

Also, yesterday, after a 160 mile trip the header

tank water level had dropped 20 mm. All visible hose

connections look intact.

Before the garage gets involved, any enlightenment

would be appreciated.
