I am having a problem with the electrical system in my soft top. Can anyone offer a solution other than to replace the complete soft top?
Thanks

Z4 soft top problem
Nothing is happening. The top will not close and lock automatically. Morristown BMW tells me that two sensors embedded in the webbing of the soft top have failed. Those sensors are supposed to control the locking of the soft top. They also tell me that the individual sensors cannot be replaced, just the whole soft top.

I read somewhere a while ago that the top has a hydraulic reservoir and if the fluid gets too low it will result in the top not operating at all. I am not certain how to get to the reservoir, but its worth a shot if all you end up needing is to refill the fluid. Here is a link to the schematic for the top and mechanism. Hope it helps.

I find no difference between the 2.5 and 3.0 as far as the top goes, but I linked to the 2.5L as a default. You didn't specify your model.

Z4 soft top problem
Thanks for the diagram.
The car is a 3.0 Z4. Morristown BMW tells me that the problem is that there are sensors embedded in a wiring harness woven into the fabric of the soft top. They tell me that the two front sensors, which control whether or not the top locks, are faulty. They also tell me that the sensors cannot be removed.
