i had my alternator replaced and since have had to reset almost daily these codes. is there a fuse under the driver or passenger seat on the e65? the vac lines look fine, it had always had some hesitation at low speed but it is now worse.
assuming these are lean mixture codes or something?
if youre resetting them daily then something is not right. the only vacuum lines on your engine are from the vacuum pump to the booster and one little on under the intake boot and neither really doesnt sets a fault if theyre open since theyve nothing to do with engine vacuum.
youve got a problem elsewhere.

Hey wdsprofess, when you had your alternator replaced how much did it cost you ?
Those codes are for your secondary air pump which is located on the passenger side of the car. Hoses run under intake manifold. If both codes are showing then your pump is not functiong correctly right now.
