I have an 06 fabia 1.2 and the driving seat when raised will not stay in position but seems to slowly collapse . Any ideas would be greatly appreciated Thanks, Davidmichaeljoh

This usually happens because you catch the height adjusting lever on the side of the seat as you get in and out. Its because the lever is a poor design and too long making it easy to catch by accident. There will almost certainly be nothing wrong with your seat.

I don't have this problem as I always have mine on the lowest setting!
