Rough idle on cold starts

What is the deal with most BMW's that I run across have a rough idle on cold starts and then clear up about 1 minute later, whats the cause of this and how do you resolve it?

older and newer engine idle control differences

the older M54 engines like what's in an 04 x3 have the issue in the video link ....idle control valve coked up

the later engines like the N52....look at/clean/swap the vanos actuators first

then ....the direct injection engines .....same as diesel injector failures .....coking at tips etc ....and that familiar diesel clack on shutdown

Just replaced my VANOS solenoids and it was cleared my rough idle right up. This was easily the most effective 15 minute repair I've done, as the engine runs perfect even on cold startup. I had gotten the sticky VANOS solenoid code and tried to blow them out with electronic cleaner and compressed air. However, it didn't really help. They were a bit expensive at $170 each from FCP, but what isn't on our cars. If you're experiencing a surging idle on cold startup, I definitely recommend looking at these.
