The large strip fuses on top of the battery for the radiator fans, cabin circuits, alternator, and some other things carry a lot of current. If the connections corrode resistance builds, they get hot, and melt the plastic.

FWIW I'm at 265,000 miles and 11 years on mine. I have not touched them.

The automatics are a weak point. The solenoids in the valve body wear out, leaking pressure, so the trans stops "fully" shifting, gets hot, and breaks various expensive parts. The only good option for a failed unit is a VW reman.
