Volkswagen gives you the same "lifetime fluid" BS. My wife has a 2004 Passat. I requested the dealer change the ATF and filter at the 90k timing belt service, and he actually recommended against it. I didn't press him and ask why, but I'm guessing they would rather have your tranny fail and sell you a new car.
Did it myself around 120k for the first time and it's doing fine now at 140k. Biggest pain was removing and re-installing the pan and gasket, on my back, with very little clearance because the car was on jack stands.
