andrewwynn will become famous soon enough
Wasn't on BMW but was on a Ford truck but very similar issue ended up being cpk (crank position sensor).

How the hell it was always either cylinder one or five the world will never know but there you have it.

My guess is cpk or wiring (including wires inside the DME or the connector to it). Clean the DME connectors
