There was never a TSB for this, as independent dealer networks are still free to use 502.00 spec oils (obviously only for T&D servicing).
The 'LongLife oil used for everything' was a specific instruction from Volkswagen Germany to all official VW / Audi / Seat / Skoda dealers that they must only use LongLife oils. This was effective from December 2008, and was circulated only via elsawin and erWin - sometime around July 2008.
So basically, official VAG dealers must only use LL3 oils, but indies are free to use any VW approved oils.
Does this help?
