VW have more "product testing engineers" on the road than any other manufacturer. They sell their gear "underdone", then customers have to battle to get them rectified, which is followed by another revision, and then more customer on the road testing.
From the link, "VW changed the type of oil used from a synthetic to a mineral one, which cured the problem". Now that's not something you read every day.
Are VW units unique or an amalgamation of manufacture components (Getrag, BorgWarner, Luk, etc) ??
