RAIN: Trunk still leaking.....You might want to check

There have been several threads that talked about the E89 roof hydraulic motors and salmon colored relays going bad from water that somehow gets into the trunk. I was one of those that ended up replacing the salmon colored relays and getting the hydraulic motor rebuilt. I promised to make sure and check on the unit after every rain to make sure it was dry.

Low and behold, it rained here in Southern California this past week, and I went to check on the trunk. The felt covered false bottom of the trunk was soaking wet and water had gotten into the lower part of the trunk where the battery and hydro unit sit. I immediately pulled the motor and made sure it was dry, and I currently have it elevated above the battery. I wiped down the recess with a towel and will let it air dry. Luckily, I have encased the foam motor cradle in a thick plastic bag so that water would not soak through.

I guess Iím going to have to get used to checking my trunk after every heavy rain. Lucky me, it rarely rains in Southern California.

Water is only a problem for the motor of the hydraulic pump, that can be destroyed by the water.
The 2 salmon relays have to be replaced anyway every 5 years as the pump can overheat.
