EWS

[Shellback]

I was going to post this under my project build but maybe others can benefit from the info under one heading.

Could the pros please post what symptoms a project would exhibit when encountering EWS (Electronische Wegfahrsperre) http://www.computersolutions.cn/blog...02/BMW_EWS.pdf or Electronic Drive Away Protection issues? Are the symptoms listed below examples of “classic” problems with EWS issues encountered during an engine swap?

A few common terms used:

Position 0 – Key is inserted/removed in this position.
Position 1 – Steering lock disengaged.
Position 2 – Electrical equipment and accessories are on/can be turned on. Cluster lights up with the usual warning lights, etc.
Position 3 – Starter is activated.

Scenario 1:
Position 2 - Turn the ignition key to position 2 but no response (dead, non-lit, zero indication on cluster).
Position 3 - Nothing, no sound, no results.

Scenario 2:
Position 2 - cluster is lit normally with the usual warning lights, etc.
Position 3 – nothing, no sound, no results.

Scenario 3:
Position 2 - cluster is lit normally with the usual warning lights, etc.
Position 3 - starter is activated and engages/cranks engine but engine does not catch/start.

Scenario 4:
Position 2 - cluster is lit normally with the usual warning lights, etc.
Position 3 - starter is activated and engages/cranks engine. Engine runs momentarily but dies immediately.
