Yes I searched, couldnt find the answer

So I drove home today and while on 95 I thought at times my var felt sluggish. Temp was good, volts were good. When I stopped at a red light, engine is running rough. No SES light. So I drive 5 miles to AZ to get my car scanned. Here are the codes
P0014 "B" camshaft position- timing over-advanced. System performance -bank 1. Explanation- camshaft acuator failure
P0301-P0306 cylinders 1-6 misfires.
P0300- he couldnt tell what this one is.
Its hard to think that all the plugs or coils failed at once, so im leanong toward the P0014 code. But i dont know what that P0300 code is. Is that the intake side or exhaust side? Damn. 133k on the clock, 02 m3. I dont know when the plugs or coils were changed last. But could they all fail at once? Any help would be appreciated, thanx

Do u think it the p0014 code that is causing the random misfires? Also noticed if im sitting still, and rev the engine to 1600-2000 rpms, and when I lift my foot off the gas as it whines down, there is an almost whistle sound for a sec

Oh I forgot to add. The engine idles right around 890-875. I am due for an oil change in 1200, according to the counter. I had just f'in filled the tank with 93 octane shell gas. 64 bucks worth. I hope its just that exhaust camshaft position sensor. Diy iz very doable. Autohausz has it for 84, .90 o rings.

Ok so I my research, I see that the p0365-69 are probably the sensors. I found this little nugget:
A P0014 DTC trouble code may be caused by one or more of the following: Incorrect camshaft timing Wiring problems (harness/wiring) in intake timing control valve control solenoid system Continuous oil flow to VCT piston chamber Failed timing valve control solenoid (stuck open) Possible Solutions This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool. Other related DTCs: P0010 - P0011 - P0012 - P0020 - P0021 - P0022

Code p0014

"B" camshaft position- timing over advanced. System performance- bank 1. Explanation: camshaft acuator failure.
So I am over due for an oil change. 10k since last. I know, I know, but money has been tight. Dont flame me. I look inside tip of motor, everything looks sludgy. Maybe thats clogging an oil line.
Also, I unplugged the wire harness that goes into the vanos solenoid pack while the engine was running. No change in idle, still idling very rough. So that is making me think that maybe my solenoid pack took a crap. 133k on my m.
So here is my plan of attack, please tell me what u think.
I am goicng to use seafoam to get all that sludge out, then do a fresh oil and filter change. While the oil is draining, im thinking I should remove the vanos solenoid pack and the mounting block where the 4 valves are. I am going to clean all 4 valves so they operate correctly, maybe sludge is preventing them from operating. Then im going to carefully open the solenoid pack to check the pins inside. I have seen the besian rebuild, and i can do that. Have nothing to lose anyway of its broken already. I have read on besian's site that the 4 seals in there are made of the correct materials, so I will just carefully clean them. Reinstall in reverse order and hope for the best. Open for thoughts

Don't forget to clean the vanos filter ... and when you reinstall the electrical connector, fix it by a plastic stripe very tight

Oh, I have a question. The 4 valves inside the vanos block, are the only valves correct? The e46's have 2 solenoid's, 1 intake and 1 exhaust. But the m has all 4 I side thw block right? Sludge could be causing those valbes to not opserate correctly, thus throwing the p0014

Have you replaced you exhaust camshaft sensor at any point? Might also be one of the solenoids on the vanos that has to be replaced.

If you clear the code does it come back right away? If not, then its most likely the solenoid.

Once you remove the solenoid you're going to need to replace the sealing plate, likely it will not be able to be reused as the seals will be flat. Thus you might as well order the Besian sealing plate kit, and the rebuilt solenoid.

Suck it up buttercup, these cars are expensive to maintain, and the repairs get more expensive if you skip required maintenance.

No I havent replaced the exhaust sensor, thats a different code. P0365-69 Ithink. So I havent thought that was the problem. I've seen posts by other people that said they got a p0014 code, changed the sensors, and still had the problem. The scan I got from autozone, Exhaust timing advanced. Explanation: camshaft acuator failure. Does that mean those valves inside the vanos block? Can u show me a pic of where the solenoids are? All the pics I've seen show them on the outside of yhd vanos, but I don't seee them on my m.

If you had looked up the instructions to replace the vanos solenoid you would have found pics of the vanos valve assembly. Here it is.

I've only read a handful of posts where the vanos valve was the problem. Most of the time it is the solenoid solder issue that the Besian solenoid resolves.

I will buy the new seals, 10 bucks. But it looks like the solenoid pack housing opens easily. There looks like are clips on the side. I can resoler the pins. And I will screw down the cicuit board just like besian does
