Finally got mine to pass inspection yesterday. 2001 x5 3.0. Replaced idle control arm, p0505. had cleaned this last year that made the code go away. Replaced disa after realizing the flap was supposed to have some resistance, mine didn't it was broke. Replaced small hoses at rear of engine that come off the secondary air pump regulator. Its in shape to sell but the wife wont let me! was going to trade up for a newer model but shes on the dave ramsey plan no debt allowed!
