Helpd P0011 & P0014 camshaft a & b over advanced
Hi all I am stumped on what to do next... let me start from the begining.
I recently purchased a 2004 x3 3.0 122k miles from a dealer as a mechanic special. It was sludged up pretty bad. I drained and flush oil several times. Able to drive it like that if i was very ez on gas pedal - Has no low end power but great after 3000 rpm. I changed intake and exhaust cam sensors. Rebuilt the vanos seals with new teflon ones. No change.. tested solenoids to make sure they actuate - and they do.
Dont yell at me too much.. next i added in my own ground to the intake solenoid so it is constantly grounded. Both solenoids had positive voltage - i think around 8-9 volts. Once i grounded the intake solenoid low end power came back- mid and high was always good and i have driven the car like this for 300 miles. Only real drawback is a lopey idle and check engine p2088. But it is very driveable..
I have a voltmeter and obd2 scanner. I would love to fix this properly - and havent found anyone with these same symptoms. Any help would be greatly appreciated.
