I'm (trying to) replace the seat heater element on the drivers seat lower cushion but I can't seem to get the correct part. I originally ordered from the dealer and was given #30675155. The shape was close but not quite right. I then re-ordered, dealer looked up VIN option codes and was told it should be #30675156 for the sport interior. This part came in and I held it up to the cushion but it's not correct. The dealer re-ordered just in case it was mis-packaged but the next one came in the same. The dealer has been really good with looking things up and I don't think the problem is on their end. Either my seats are something unusual or perhaps there's a batch of mis labeled parts?

Does anyone have any info on this? I'd really like to have a heated seat but I'm not having much luck and I'd like to put the seat back together.

Thanks

It is possible the part has been upgraded.
