BMW R1250GSA cam actuator test

[halejl]

R1250GSA using the gs911. I got: A negative response was received from the vehicle; The preconditions or sequence order was not met for this controller.

Does anyone know what this means? The bike runs fine. When doing the test I can hear the cams changing and the rpm changes along with cams. I just had the covers off checking the valves and everything seemed ok. I have received fault codes a couple of times about the cam position being impossible. The fault seems to heal itself and the bike runs fine.

if the camshaft actuator goes bad, will the bike continue to run ok, just not switching on to the high rev cam? Does it go into limp mode? Thinking about what might happen if the actuator fails while I’m in a remote location. Am I worrying too much about this?

If the camshaft actuator is failing, the bike may continue to run, but it may not be able to switch between the different cam profiles. This could result in reduced performance, fuel efficiency, or emissions.
