I have a new to me 2008 1200GS without ESA or tire pressure sensors. After reading this (https://gadgeteer.co.za/mybike/bmw-r1200gs-tips) I was able to deactivate the ABS. My issue now is I can't set the ASC because the indicators on the multi-function screen never turn on. When the ignition is on before the engine is started the top line error light cycles through the red and yellow triangle and then dims off. I have read all the cryptic instructions in the user manual and they are more confusing then helpful. Anyone have ideas?
