The 3.2l TT uses the same master cylinder as the TTRS and I looked it up and the 3.2TT booster is the same part number as the TTRS: 8J1612107D and the superseded part numbers are the same ones that are used on the regular TT and TTS, but with the mk6 GTI sized MC. The TT 3.2 and Tiguan booster are definitely larger than the stock GTI Booster.
