[BiturboS4] Rumor(s) Behind The New S4

[Steven Lin]

What Philip meant by taking apart the ECU was to take the plastic
cover off of the box enclosing the ECU.  Stamped right on the top
you'll see the part number along with the ECU revision (e.g. A, H, M,
etc.).

The ECU revision is also retrievable through a VAG tool connected
to the OBD port.
