Are you absolutely certain the part number for the tray is 51169181218? Maybe I'm interpreting it wrongly in the following diagram and description, but the part number you referenced seems to be one designed for a mobile phone - not a plain tray. I would have thought the correct number would be 51169181229.
Edited to add: The more I've subsequently studied the actual parts link
http://www.realoem.com/bmw/showparts...18&hg=51&fg=35 the more I'm wondering if the original number 51169181218 given is, in fact, correct. The color coding for the items in the descriptions is throwing me.
I'm in the process of making an arrangement to order this tray and mat from a supplier in the UK and want to be certain I'm asking for the right thing.
Thanks for your help!
