Unknown electrical device below firewall resistor

[Der Dicke]

Hello,
I have some electrical problems with my K30.
I found an device below the resistor. When touched, the component disintegrates. probably a diode or capacitor.
The pink cable goes on to the starter
Any guess?

Greetings from germany,
