E39 530i SES lights / Reduced power

[euro2fast4u]

Been having a few mechanical issues with the car and finally a check engine light has came on to help.


Prior to SES light. Occasional brief reduction of power and additional engine noise. I could drive along, park the car, finish task, get back in car, and drive away. It seems this was the only way to get the issue to reacquire. Brief loss in power, engine was noisier, wasn't as quick/seemed to struggle. Then within a few minutes it seemed to be back to normal. Seems to have been more pronounced over the last 3 months (assuming because its been hotter these months)


Yesterday similar thing, went to the DMV, as i was leaving SES came on. Pull out the cheap scanner and have two codes.


P0369 - Camshaft Position Sensor "B" Circuit Intermittent


P1619 - MAP Cooling Control Circuit Signal Low


I should say the loss of power is more noticeable now and seems to not "go away".


Where do i begin? need to find my Bentley but most times the forum is also a good start.
