Hello friends of the automotive extra class, today I noticed on the floor of my garage an atypical accumulation of an oily brownish (of the consistency aqueous-oily) substance. Then I lay down directly at the front under the radiator grille of Phaeton. Here were pictures that you can take from the attachment. Does someone have a remote diagnosis idea what it might be? The servo oil tank was normally filled. All inspections made according to VW. Also recently with Zottel. Engine bearing?
