Crank sensor seems like a possibility...

Still scratching my head on the EWS, now that I think about it Upallnight is right. My memory is not the best and we saw many cars with EWS errors but I think they were in fact no crank situations...

He suggested good "no start" general practice diagnosis... engine only needs three things to fire. Spark, fuel, and air. Find out what's missing and go from there.

Edit: After looking at another thread, I think my first check would be the fuel pump. Ridiculously common failure... really easy to check usually, though not sure how easy on the e53. On e30, e28, e39, e36, and e46 it's right under the rear seat. Pull up and listen for pump.
