Hi Guys I do not know how relevant this is but when I reinstall my instrument panel on the ST3 the rev counter buzzes for about15-20 seconds,I presume this is the CAN bus with the Instruments checking in with the CPU ,this is before I even turn the key,as there is some information that is just kept in the instruments,could that be data about the ignition key and the pressure sensor?
But never had any issue once the buzzing stops just starts up like normal.
