Middle Seat Belt Part Number + Compatibility Help

[paulouis]

Hi there,

I have a 2011 S4 and I'm replacing the rear seat belts. I was able to get the part number for the middle seat belt, but it's incredible difficult to source.

8K0857807L

What would a good resource be to see if there's other part numbers that are compatible, maybe from an A4 or alt years, B8.5?

Thanks!

It's 8K5 857 807, now 8K5 857 807 AH, if you have the non-folding rear seat backs.
It's 8K0 857 807 L, now 8K0 857 807 AG, if you have the folding rear seat backs.
Others you might find, such as AE, AF, etc., are not US regulations compliant versions.

Fantastic. Much appreciated. For future knowledge, where did you find this info?

middle belt is #9. PR 3ND is fixed rear seat backs, PR 3NZ is folding rear seat backs. The problem is it's showing the RoW safety compliant (PR 5C0) versions, even though the USA market is selected.

The proper page by Audi USA. Though parts.audiusa.com got it right this time (you don't see the fixed seat back versions because the S4 didn't come in Premium trim, the only version for US B8.0 that came with fixed seat backs), it's often a complete pita to find the correct diagram, and it often removes a lot of stuff from the diagrams.

The best resource is https://ifinterface.com/page/page3.php > CarProg2, but nothing in it can be posted in a link fashion, so you just have to know where to find what you're looking for.

The legitimate resource is partslink24.com, but I'm not paying their monthly fee to help others with their forum questions. It's an expected resource for a shop or dealership, but not private individuals.
