What's the 2005 VW Passat TDI transmission fluid type?

As transmissions are some of the most expensive components to replace in most vehicles, it's important that You use the proper recommended transmission fluid in any car. Specific to Your 2005 Volkswagen Passat TDI, if it's equipped with an automatic transmission, You're recommended to use VW G 052 152 A2 (TL52162) automatic transmission fluid. Now, some may balk at seeing a proprietary transmission fluid -- "Surely, there's a substitute, right" Of course there may be fluids that are similar, or even potential subs. However, this isn't what's recommended by the manufacturer -- the people who know their vehicles best. Therefore, I'm going to recommend that You spend the few extra dollars and go with the manufacturer's blend, because other options won't hold a candle by comparison, especially over the long term.
