2000 328i Camshaft position actuator tight or jammed, P1523

trying to figure out why this problem is causeing my check engine light to be on, the other night i bottomed out my car on a pot hole cracked the oil pan and didnt realize it at the time. the next day i drove the car a few miles before i realized what happened and the car had no oil.
I fixed the oil pan and the car holds oil now, The engine sounds like it is running normal but the check engine light is trippin me out and i am getting this code P1523 . would running the car out of oil of cause this code to come up or would the impact of bottoming out cause it? any help is apreciated ty.

It appears to be a vanos problem. Having read another thread recently about oil pressure and how the vanos unit works, I'm a little concerned that you may have some pretty serious damage running the engine without oil.

No, it does not sound right at all. Sounds like the vanos actuators got stuck because of no oil to me. I would drive it hard to try to jar the actuators loose to begin with and if that doesn't fix it, I would order both sensors and DIY them. There are posts on here to help you, you really don't need help for the exhaust one, but the intake one is a bit harder to get to and you will need a new vanos o-ring and oil hose washers. I happen to have an extra vanos o-ring if you need it.

BTW, by car was giving me that code a long time ago....I lived in a cold environment and my thermostat was malfunctioning, so the engine temp would never warm up...I had mayonaise stuff on my dipstick. After I changed the thermostat, the mayo went away, the car was warming up to normal, and the vanos stuck code went away by itself. Yours is probably unrelated to the thermostat though unless your situation is similar to mine.

so i took my car to the bmw shop , had it inspected cost me 113 $ not so bad there, wanted to know everything that was wrong got a bill for 2500.00 thats 1/4th the price of the car, frickin crazy. they told me the sensors may not need to be replaced but they need to start out by changeing the vanos solenoid.(200$ aprox. ) and a vanos gasket seal/ v/c gasket (360$) . so JVR was right in saying it was a vanos related problem, now i have to hope its just the solenoid and not the sensors, is there a walkthrough for replaceing the vanos solenoid someone can give me a link too, thanks for all the help and input so far.

First, check to see if you have an OEM exhaust CPS. Use a mirror and flashlight to look at the side of the CPS. If it's OEM it'll have a BMW logo. If it's not OEM replace it with a part from the dealership.

Second, replace the vanos exhaust solenoid valve (piston). It's #4 on this parts diagram. You'll need a deep 32mm socket to take off the solenoid while the vanos is mounted. You might need to remove the fan/shroud for work space. You will get oil drainage.

Third, replace the vanos seals.

Please find a good mechanic that works on imports and stop taking it to the dealer!
