Had this happen on my 2009 E92 (2/09 Build Date) - it was NOT the bulbs.
Took it to the dealer, they stated 3-series cars weren't affected by the TSB - only 1 series??? Pulled out a copy of the TSB - they ended up replacing both bulb holders & bam! no more ghost errors
These should be replaced BOTH sides with new version:
Shown are the new versions - couldn't really tell any difference between the old & new, but I didn't spend a lot of time comparing...
