I had a 99 VW Passat with a V6 and 5spd manual. It had a sunroof that when clogged, led all water by default underneath the driver's seat. Under the driver's seat was the ECM. One day the car wouldn't start and I diagnosed the car as having a bad ECM and when I looked, it was frozen in ice on the ground under the seat. When I unplugged the ECM, tons of wires just fell apart. Bottom line, a junk yard ECM plus I had to cut and splice 32 different wires. They were all the colors, plus when the colors ran out, some of the wires had stripes on them. So the red wire wasn't the same as the red wire with a tiny thin line of yellow on it. But I took on the project and when it was over, I had the satisfaction knowing that I fixed the problem myself. I immediately waterproofed the ECM and the wiring. I do own an OBDII computer but I understand that it only scans basic codes. I do understand that the Crossfire has multiple computers and I'm okay with that. I think all cars do these days. My Eclipse that I have has tons of aftermarket computers on it that are setup to be connected to a laptop and setup that way. When I installed a new battery in the car, I lost all the settings and I don't know how to program it with a laptop. It's too complicated for me. So the Eclipse is for sale. So I understand that I'll be buying a car with multiple computers but I'm okay with that. I've heard that the trunks can fill up with water and is a common problem. I haven't had anyone chime in with any answers to how to fix this. I guess I'll run a Crossfire through a carwash before I buy it. Also, I used the Mother's headlight polish kit on my Eclipse and it had a foam pad on a drill bit. It helped but I was disappointed in it. I'll try the 3M one next time.
