AFAIK that's not possible.
  • Replace the salmon relays every 5-8 years, the production date is printed on the left side as WWYY. These parts can stop the roof movement as well as kill your hydraulic pump due to a melting contact
  • The trunk vents on both sides behind the bumper seem to be the gates for the water, should be replaced after 8-10 years. All 2009er I've looked at had this issue
  • The foam below the hydraulic pump is water sucking instead of water repelling, should be replaced and kept dry
  • The foam below the hydraulic pump doesn't stop burning

We are discussing about these topics in the German ZRoadster forum as well:
