It might be your camshaft sensor that went out - either that or your VANOS seals.

Some discussion on the topic at:

I personally haven't experienced it but first would test/replace the sensors before replacing VANOS seals as the sensors are known to go out. Bentley has a Youtube video of testing the sensors but requires an o-scope... Other option is taking it to a certified BMW mechanic to have them troubleshoot it and if they deem it is a sensor, find out which one and then you replace with an OEM sensor (if you are mechanically inclined - lots of Youtube videos showing how to replace sensors).

Sorry I can't be of more assistance - maybe the folks at Bentley can assist - shoot them an email.

Let me know how it works out.

Cheers

Update - if you have determined it is not a faulty sensor and is your VANOS, here is a DIY on how to replace the seals in the VANOS:

Not that bad of a job if you are mechanically inclined and a lot cheaper than a new VANOS (about $40 for the VANOS seal kit at BavAuto - and another $50 for the valve cover gasket set and $5 for the VANOS gasket... a new VANOS is around $700).
