ok so i have had to replace the driver seat from my A4 as part of the frame in the back of the seat had broken. this meant i would move back when accelerating and forward when breaking (annoying!). got the new seat fitted last week and its great, except for the fact that the switch for the lumbar support dosent work. i want to swap the switch from my old seat into the new one, but i dont know how to do it?? had a look at the old seat earlier and i dont have a clue how to take it out. wouldnt even know whereto start!! any help appreciated.
