[416tourer]

Hello all.
Both my Tourer and my friends Tourer have the same fault.

The larger of the two rear seats will not clip onto the catch when returned to the upright position.
Has anyone else with split rear seats encountered this problem?
I pulled the seat apart .....as much as I could, and found a small spring had detached from one end, put it back on, but no difference.
The knob will depress to unlock, but not return to the upper position by itself.
I have been manually able to reach behind the squab and lock it on to the catch, but this is a real pain as you have to pull everything apart to get to it.
Any suggestions as to what could be wrong/how to fix?!
Oh yeah.......the smaller seat split still works fine on both our cars!
