Fairly recently this noise has started everytime i lean back into the seat then lean forward agian. It's like a click - clack noise. It's a series 1 Berlina with a over 200k's on it. The noise seems to be connected with the lumbar support. If i wind up the lumbar support to the max it goes away... Yay, but i get a sore back lol. Has anyone had this same noise before? Is there a fix for it or should i put up with it or replace the seat from a wrecker ??? Other than this is drives great and has very few noises.
