"Need To Know Where The Engine ECU Location on 2001 Audi TT"

2001 Audi TT Engine Block

Does anyone know where is the engine ECU located on my 2001 Audi TT? It doesn’t mean that I want to replace or removing it. Thanks for any helps.
Answer: I just looked through my Audi repairs and services DVD. The ECU for the 2001 TT is located under the hood, in the center of the plenum chamber (behind the engine block).
