Yes, the fact the tech told me at first it should go away on its own did not give me a good feeling on his knowledge. My car was raised high when I first picked it up after replacing the struts and that was a visual indication height were not reset to normal.
Now his recommendation is to get a "donor" E53 with a working module and try it on my to see of the module is at fault...
I notice he is listed as "blue" certified tech - does blue mean rookie?
