I used to have an E46 with the same engine/transmission (5spd) 2006 coupe, even same mileage and I never heard that. I was going to guess fan clutch... the M52 uses an electronic fan right? So it can't be that. You should have someone stand over the engine bay as you rev it up. Maybe ask a smog station if you can borrow their dyno rollers so you can drive through the gears. Pay for a smog check.
