93 closing convertible roof problem

[mark387mw]

I have a 1999 93 convertible that has developed a problem when closing the roof.

Most of the operation is completed up to the point where the hard plastic tonneau should lower.
It doesn't and soft top failure comes up on the SID.

You can sort of jiggle it and encourage then it will complete the close but I don't know where the problem lies in order to fix it.

Any clues where to start??

It will fail in the closing operation when the plastic cover is 90' vertical. I've heard it's the microswitch in the rear that will work if "bashed" around the trim panels behind the driver. Yet to do this as I'm away from the car this week.

Fluid level checked - found to be low.
Fluid level topped up - satis.
Functional check carried out - satis.

What a PITA putting the pump back - too many cables getting in the way.
Anyhoo, all done and is much quieter in operation.
Hopefully there is no major leakage and this job will last for some time
