Removing and installing fax unit contact switch F86: Audi A8 D3

🧭 Before you start

Switch off all consumers and remove the key, take out the rear centre console and turn it upside down. Close the roller blind, unplug the switch and remove it from its bracket or housing. When refitting, set the switch on its nuts or slots so the operating rod switches it with the roller blind open, start the bolts only a few turns while positioning it, then tighten and reassemble the console.
