While working on my 1997 850Ci headlight loom today I went and pulled a spare loom off of a 1992 850i parts car and was very surprised to see that the wiring on the late E31s was much lighter gauge with a hard plastic insulation that is deteriorating/cracking on both of my later cars. The wiring looms are on the fenders no where near the engine and are not exposed to extreme engine heat. Why are they deteriorating so badly???
The loom off the 92 850i parts car looks original and it has thicker wires with more rubber like insulation...
What was also unusual is I have several old German cars (356 +911 Porsches, 280SL MB) from the mid 1950s to the 1960s and unlike English cars the German wiring was always considered absolutely bullet proof even when almost 70 years old!
Not so much with the E31s?...
Maybe the new hard wiring is BMW planned obsolescence? When your car catches fire and burns to the ground you will need a new BMW.
I also noticed the tool kits were different in the later E31 it is missing the large 17/19mm wrench by design...

Subtle differences between a 91/92 850i and a very late (96/97) M73 850Cis
