Hello everybody, I am new to the Passat World. Just bought a 2009 Passat 2.0 T three months ago and I am really loving it. I have a question: are there substantial differences between the new 2.0 TSI (code CCTA) and the previous 2.0 FSI (code BPY)? Thanks in advance for your help; I will post a few pictures soon.

Greetings from Brazil!

as per vortex

Some major differences from the FSI to TSI include:

- chain driven belt
- fuel/engine management
- components in the intake system
- oil filter and oil dipstick relocated
- improved PCV system (proved to be problematic in the FSI)
- compression ratio lowered to 9.6:1
- more balanced cam shafts in the center of the block on both sides
- down pipe
- fuel efficiency (debatable)
- better emissions
- more 02 sensors on exhaust system
