Thanks, I spoke with a Volvo service guy who knows little more about this than me. I was hoping for an easy quick solution where I could simply pop the cover off...NOT. He suggested using a product called Dum Dum which essentially sounds like a urethane type of tape that can be molded into place. I would have preferred to seal the leak from the outside of the cover where the water comes from however I guess I will give that a try before the next rain (here on the Canadian wet coast)
