Have you ever closed the roof to be met with it stopping short by 5 inches?
Your immediate reaction is to check the front of the roof...
..but the problem is a little further back. Between the roof ribs, the roof material
is supposed to fold outwards. As you can see, this isn't the case here.
The roof material has trained itself to fold inwards which catches on the roof spar rubber seals.
As it pulls the roof over it, the resistance rises and the roof motor cuts out
because it thinks the roof is fully closed.
Some people don't realise and manually help the roof to close and quite
often you will get a deformation of the side spar seal.
If this happens, draw the roof back and push the seal back in place.
Power the roof so it is covering the entire back of the car.
Look to the side and chances are the material will belly out as shown below.
However, the material is supposed to belly in like this.
To fix the roof you have 2 choices. You can either manually push the fold outwards every time you close the roof or you can attempt to retrain the fabric to fold out as it should do.
To retrain the roof fabric you have to go against what it says in the manual.
"Do not leave the roof down when wet".
With the roof fully up, brush it clean and wet all of the roof. Carefully power the roof back making sure that the roof folds in the correct direction. You can open the boot and apply pegs or bulldog clips all the way along the problematic fold. Keep the roof folded down for 24 hours and test it out.
You could also try wetting the roof by using some soft top cleaner. Fold it down
as before and when you finally fold it back up, apply the soft top finishing spray.
