pop the hood.
go to the far back right of the engine bay. theres black box with about 4-5 screws in it. take them out. the one on the back is a pain. take the cover off and boom. ecu.

By the way, you will need to remove the plenum cover before you can get to that part of the engine compartment. To do that, just remove the gasket away from the front of the gigantic plastic piece, and then the big plastic thing will come right out.

3BG = B5.5
3G (or is it 3B) = B5

Is it a european thing to say 3BG rather than B5.5?

Thats how it is for them...B5 is a US term. Thats like someone asking us why we call it a B5?
