Top works, trunk soft close too, why no central locking?
Just like the title says, top works, trunk soft close too, why no central locking? Yes, I checked the fuse. Any ideas?

Since the locking system doesn't respond to buttons or the key, I would presume the problem is with either the pump or a leak in the pneumatic tubing. If you never hear the pump run when you try to lock/unlock the car, then I would further presume the problem is the pump.
My next step would be to check the system with Star Diagnosis. I would see if any faults are present, and I would see if the pump can be actuated to lock/unlock the car from the PC. Those steps would prove conclusively that the pump is faulty and needs repair or replacement.

Is your pneumatics seats fully functioning? Thats another good place to start looking for leaks. Check all massage, lumbars to insure that they all fully function. My leak was right at the pump as a plastic hose connector cracked and I ended up having to replacing the pump. However my dash locking button still doesn't work after pump replacement.
