The oil housings on these vans are made of plastic and are broken easily during oil changes. We lost all the oil and it ruined our engine. Each time we get oil changes we have to ensure the housing is not cracked. We asked Volkswagen to recall these vans but they refused. We absolutely hate the van because of this issue!
Replace the plastic oil housings which get hot and brittle and then crack leaking out all engine oil. Replace them with metal housings.
