elv lock error
I have a BMW e90 320d from 2005 with Comfort Access (keyless go) and I have experienced the same problem. After a week in the parking lot, my car got the yellow lock error and would not start for 3 days. I should mention as i think it is very important that the battery went weak and this most probably triggered the problem. I changed the car's battery and still yellow lock error. But this morning I went to have another try and the error was gone and the car started with no problem....and no error.
I I have read in this forum the problem might come back as this is a ELV locking system common issue.
I will be back with updates
