It's saying control fault means the vanos solenoid or actual variable gear inside is not doing it's job.

Bank one is the starboard side bank two is the port side.

Most often people will start with pull vanos solenoid and clean then on cars where it's easy enough to get to them swap banks to see if the problem migrates.

Bank two is cars left side will be on your right when facing the front of car.
