Hey guys.

I recently had this code come on.
I searched the forums and someone on N55 forum mentioned changing gas cap fixed it so I ordered this https://www.ebay.com/itm/OES-Genuine...72.m2749.l2649gas cap and put it on, but it came back after clearing the code and driving for a few days.

Any idea on what this may be?
Thanks for the help guys.

The gas cap you purchased is an older part number. It should in theory work but the new part number is Genuine BMW Filler Cap - Part Number 16-11-7-222-391

It replaces: 16-11-1-184-668, 16-11-6-754-491, 16-11-6-756-772, 16-11-6-765-046
