I hope someone can give an idea about this old problem.
Replacing the back axle in November, as part of the job I used the boot rails as a way of tying up the calipers out of the way whilst changing the complete axle, for this part it worked great. To make life easier we had the roof open, but then the rain came and unfortunately I tried to close the roof whilst it was still tied down. (What a total pratt!) Realized quite quickly and took off the cord, but too late, the roof wouldn't close. Thanks to this forum found out about the manual close and did that.
Assuming an issue with the pump I firstly changed the fluid, still nothing. The fluid that came out was very black, and after trying it the new fluid did change slightly darker, which seems to show it is pumping. I then got a pump from a breaker and tried it, exactly the same result. At all times the pump is heard running and the locks release and lock on the upper boot lid. Thinking it is to do with the upper lid lifting I then got a pair of rams and changed them, but no joy.
I did think that as I have a pair of the rams spare I might look at trying to renew the seals in them.
The last thing I am debating are the sensors for the boot lid, if they are saying it is locked would they stop the action but still let the pump run?
Any help would be greatly appreciated.
