Same question here
I want to retrofit alarm to my recently purchased Z3. European Z3 CM11, prewired for alarm, no DWA module
I successfully retrofitted cruise control (actuator, double cabled butterfly, CC Stalk and CC module), succesfully added remote lock unlock ( mirror, the harness needed from mirror to the pre wired plug below dash) but have a problem with alarm...
Although my Z3 its prewired ( siren added, bonnet switch added, Tell-tale Led added, tilt sensor added, ZKE coded to retrofit alarm antitheft via a BMW dealer ) after adding all required parts, when I press the lock button in my key ( three button, with the big BMW lock button plus unlock button and interior light button) nothing happens. No tell-tale led flash ,or indicator lights blinking)
Any thoughts?
