Part number 8E0 881 401 AK VEH
It is finished in Soul Metallic Valcona leather (i.e. the standard interior colour for RS4 Bucket seats).
It was bought as a just in case spare, but remained unused before I sold my RS4

If the bolsters on your bucket seat are looking a little tired, why not replace the cover?
These are normally £350 from the dealer.
I am looking for £125 including postage.
