Chassis no. of any Audi A8 4E D3

Ladies and gentlemen,
for my A8 D2, 2002bj. the comfort seats of Audi A8 4E D3 4.0 TDI 2006 acquired at e-bay. Since there's no electrical fit, you need schematics. However, the purchase at Audi - you need the chassisnr. E-bay seller unfortunately does not reply. Can someone be numbered to me? of course, if such comfort seats were present in the original version.
