I am familiar with the cooler you speak of. In
several years of reading several VW forums, I have
only ever heard of one failing and leaking oil into
However, with VW diesels, it isn't all that uncommon
to have a head gasket fail, and these are common
of a failing head gasket. I am sorry to break it to
Whichever thing it happens to be, the only thing to do
is replace the part, either the cooler or the gasket.
I suppose you could pull the cooler off and take it to
a radiator shop to have it pressure tested. If it
leaks, then you are lucky and all you have to do is
replace it and clean out the cooling system. (The guy
dealing with the one instance of this failure I've
seen used some Dawn to flush the system several times
then gave it a good rinsing.)
However, I'd give you 95% headgasket, and 5% oil
