With all due respect, were you pulling codes or were you running diagnostics? Two different things.
You do a disservice telling people "EGR Codes do not set CELs" if in fact you were running a diagnostic test and not pulling 'already set EGR faults'...
A CEL is set by a code, period. You cannot have a CEL come on without AT LEAST ONE underlying code.
In your other thread, your mechanic said there were no codes for your CEL, correct? That is why I said he is lying. He may have erased the existing (historical) codes, then run the diagnostics- which showed no 'present' codes.
Again- 'set codes in the OBD' versus 'BMW diagnostics'- different things
