I recently got a 2003 SL500 and when checking the Headlight bulbs I found that the insulation cover is damage, it crumbles to pieces just by touching them. I checked other cables in the car and they seem to be OK and the electrical systems are working fine.

I'm wary this could lead to electrical shorts and failure in the electrical systems, Has anybody else noticed this degradation in the cables? how can this be solved / prevented?

I have not seen this in general on Mercedes wiring, but I recently encountered the same problem on some R170 xenon headlights of a similar vintage.

This might (hopefully) be limited to headlight wiring that was supplied as part of purchased headlight assemblies (wiring manufactured for and installed by headlight manufacturer).

Apparently this is an issue with early eco plastics.

All of my German cars from the mid 90s to 2006 have this issue. 996 Porsche s , 2006 cls55 3 r230 and c32. And e55. Some are worse than others but it’s garbage wiring. Plastic and rubber always take the German cars out of commission,
