Im doing a TÜV now and need the betriebsanleitung for Recaro racing seats from 2003 for my 928. Does anyone in Germany have an idea how to find them if they even exist? Attached is the picture with the code numbers in a fairly rotten state. I will be returning to the original seats (for which I have the bases if anyone in europe has the tops?) in time - the TüV will allow me to register, insure and drive it finally. Ill post on PFF too.
