BMW does state in ISTA to program the DME with the latest software when repairing the valvetronic system. It appears software was playing a role in failures.
The oil spray nozzle has not changed part numbers: 11377583786 I BMW just recommends replacing all 3 items to avoid double labor in the event that a tech puts in a new motor but the issue was the nozzle (cheap part) was clogged. Or, the tech replaces the motor but the issue was poor vehicle maintenance and the eccentric shaft itself is worn. 99% of these failure appear to be the electric motor failing.
