He was talking about the TT petrol engine, there will be a TT TDI at some point - think its in the new passat is it not...??
No he wasn't! What part of "twin turbo TDI", or "twin turbo diesel" did you miss?
And there
maybe, at some point in the future, a twin turbo diesel. But it aint here yet. And if it does get developed and produced, it will probably only be for larger cars, with larger engine bays, such as the Passat, and longitudinal Audis such as the A4 and above.
