This part shows as available from Germany according to my local BMW dealer, although I’ve been waiting for the part since July.

Yeah, my understanding is that it’s backordered.

It’ll eventually become available but was hoping someone here has one for sale.

I have a #51481881594 I can part with if anyone needs one.
Did these change shape over the years? 51481881594 seems to be later, while 51481904314 appears to be early? (on realoem).
Anyone know if they're interchangeable or how they differ if not?

These are completely different parts.
51481881594 is part of the three piece hood self adhesive insulation, a triangle shaped flat foam part.
51481904314 is a scoop shaped part the directs airflow from the top hood vents.

The scoop shaped part is attached to metal of the hood also scoop shaped so it is sound deadening and may be there for a better seal. could be duplicated for the non-intensive, non-ocd concours guys which must have perfect. The dup might not have all the cut-outs and the attaching plugs that the original has but hey it would be able to do the job BMW intended.

Glad to see you are typing. Hope the recovery goes well.

Ah, thanks for the correction. Not sure why I didn’t recognize this on the realoem fiche.
