Hi Trapper,
the infos about installing height adjustment for the passanger seat are as follows:
For a Leon 1P with sport seats, no heating it should be
seat frame left hand side (passenger)
1K4 881 105 KK .......... 215€ + tax
(since identno. 1P-6-010 000 has to be 1K4 881 105 GQ)
height adjustment
1K0 881 053 A ............. 42€ + tax
hand gear (lever)
5P0 881 091 C ........ ??? (sorry, received no reply on this price)
handhold
5P0 881 254 1MM ........ 12€ + tax
That's supposed to be needed for re-fitting just the frame ... the rest of the seat incl. the seat's rest should remain and the seat's upholstery only has to be tied to the new framebox ... so I've been told.
By the way, it looks like it's all the same if you have sport seats or regular or leather ones with or withour heating ... it's all in the frame - so to speak - i.e. no matter what seat has to be fixed to the frame.
All in all it's a pretty expensive exchange for just a little more comfort ... add the working costs and you'll be spending probably more than 400 Euros (~
280 pnd) just on the height adjust.
Important: All the above infos were given to me by a friend from the german forum and there is no warranty on any partnumbers or the approx. prices.
He checked for me as far as I understood the threadstarters request. So no guarantee from my side.
Nevertheless ... hope this helps.
Klaus
