Maintenance/Repairs

I have a 2000 Mercedes CLK, and it recently started having electrical problems. Next, I discovered that back in the early 1990s, The EU started requiring cars to have biodegradable wire insulation. The first few years (1992-1996) are supposed to be the worst. On my car, I noticed some insulation cracking on the headlght wire harness. Then I found that the trunk wiring harness has the same problem.

I am wondering: do all European cars still use biodegradable wiring insulation that falls apart? How long is it expected to last? Do Japanese and American cars have the same problem?
