E93 M3 starting issues

Impastokitsch · 09-08-2019, 06:31 AM

Car always have elv fault code. After clearing them, it will come back

Car comes with comfort access

Problem not so frequent until recently i changed my battery and alternator
(Before changed of battery, this happen once every 10 cranks)

(After changing of a new bigger amp battery, and new alternator, it happen everytime) battery was registered via ista btw! Voltage running smooth 12.3-13-5v

The video clearly will shows what is happening

The car will only start up after 3-4 tries of off- on ignition

Tried checking via ista and it shows CAS having issues and mechanics are recommending to change CAS module

Could this be fuse or the module?

For anyone looking at this now, I have the same problem on an E92 although the car is not stuck and the ELV is still functioning.

The problem for me is that the ELV is connected via the CAS module to the Comfort Access module. If I disconnect the comfort access module, I can clear the ELV fault A114 - which relates to a Line fault.

My issue now is that I don't know if it is the module causing the issue or the door handles, but whatever it is, it is not the ELV.
