Hi guys,
I started the car one morning and the car began to idle very roughly. I try to let the car sort itself out, but soon enough a CEL goes off. I grab my Evolve cable and scan the car. Sure enough the codes point to the Vanos on bank 1.
Got the following codes:
48 Intake camshaft Vanos retard valve, Cyl#1-4
B8 Intake camshaft Vanos position control, Cyl#1-4
43 Intake camshaft Vanos advance valve, Cyl#1-4
I didn't want to drive the car in the current condition but I eventually took out the board, and had my buddy resoldered the joints, freshened up the orings, and tested each of the solenoids with a 9v. We thought all was well, and went back to installing the board. I even ordered the new covers (since mine is a 2000) with the set screws (damn cost me around $200) just for the covers and screws...
I reinstalled the board, test drove the car around the block, went and cleared the codes. All seemed to go well for a few days. After awhile the codes came back. The second time the CEL went on first and idling and drivability did not change.
The next day the car started to have intermittent rough idling. I drove the car a good distance to see how it was driving. I couldn't feel any misfiring, but I could tell the car was definitely down on power. The rough idling would come and go. During initial start up the engine would idle very roughly. Later on the engine would smooth itself out and the rough idling would go away after maybe 10 minutes of driving.
I scanned the car, and same set of codes were present. I took out the vanos board again on bank 1, and AH HA!! Noticed one of the yellow wires got pretty chewed up.
Could this be causing all the issues/codes?
It's really such a shame that the s62's reliability and power can be plagued by such a small little device. You would think BMW would have designed a better solenoid board since the motor is so dependent on these units.
