    2009 1200rt esa, shock problem
    « on: 2019-10-22 22:50:09 »
    I've had my bike a few months now and the only issue is the pre load will not change. Holding the button has zero effect.


    I tried applying 12v directly to the 2 pin connector in the motor nothing happens other than sparks on the battery, in addition the resistance across those 2 pins is less than 1ohm, so I'm assuming a blown motor. The error code is esa position sensor error.


    However while looking at replacement shocks on ebay I notice they are all, black. My sho k itself is a very distinct yellow. Does that, sound like it has been changed to an ohlins which all seem yellow. In which case would the esa, work on that shock anyway?

        Just a thought, the pre load can only be adjusted after starting the engine and whilst the bike is stationary, not on the move.

          I might be wrong here - I often am! - but if it is an Ohlins unit (possible, as they usually have a yellow spring around a yellow/gold body)....I don't think they offered ESA/EC for an '09 RT......which might explain why the button does nothing!

            This thread from BMWLT, https://www.bmwlt.com/forums/rt-series/45201-ohlins-esa.html suggests that, "Installing Ohlins will remove ESA function."

              if it's any help I have a 2007 R1200RT with ESA, it has Sport, Normal and Comfort modes. Plus modes for one rider/two/rider/luggage etc


              I have tried all the different modes, and they do work, as I feel the pre-load adjusting, but I don't notice any difference at all when riding. i think you have to really push it in the corners to notice any handling difference

                That's what I'm wondering.


                And I do know exactly how it should operate, but when stationary my button does not change the esa helmet display, I'm not unsure if it's working, I'm 100% certain it isn't working properly for preload, but the Ohlins might explain it.

                  I might be asking the obvious here, but have you had a proper look at the unit? Ohlins usually have very obvious stickers on them that say......Ohlins! Does it have a power supply to it?.....lift the seats and have a look.

                      Has it ever worked since you've owed the motorcycle?

                        In 2014 I had a problem with a sticking ESA shock on my 2005 RT which I mentioned to the chief technical officer of BMW UK (Motorrad) at a bike show.


                        He suggested that I have the chassis software updated to the latest release - which included a change to the stroke of the ESA unit to prevent it reaching the previous extremes of travel. 9 years of software updates fixed the problem and the technicians are are able to precisely measure the travel of the shock when it is cycled.


                        Having got it working, I then sold it to someone who was only ever going to ride solo and therefore would not need the chassis adjustment if it stuck again.


                        Had I intended to keep the bike, I might have mounted an aftermarket unit.


                        Hope this helps someone......
