So I’ve got oil in the coolant. (07 Passat 3.2 vr6). Is there anything common that fails? It smells a bit like dsg fluid but hard to tell. I took the dsg filter cover off and there isn’t any evidence of water in the trans. Also no evidence of water in the engine.
I guess the options are trans cooler, head gasket, engine oil cooler (if it has one)?
Any thoughts?
Thanks.
