It's been recommended by Volkswagen for years; a couple things to watch out for though-
Chevron sell a similarly packaged product that _contains_ techron but isn't _all_ techron. Don't bother with that. Might be called 'Pro Guard'?
AFAIK it's not recommended for continuous use- you can run it in two consecutive tanks, but then you should probably change your oil.
Good luck,
Robert
