I searched and could only find a topic that showed someone having an issue calibrating ESA on a K1200S without the hall sensors, but I figured I will share my story of how I fixed a stuck rear shock on my k1200S.
A few weeks ago the bike seems to be stuck in the 2 rider position. When I cycled through the positions, they would show, but it would not "blink the display" like it used too. The ride solo was very hard. I looked at the rear shock and it didn't move.
I bought the GS-911 last week (didn't want to wait for the WiFi version as I had an immediate need) to try and calibrate it. Well, with the latest beta version of the software it told me "No ESA can be calibrated is fitted for this motorcycle". The buttons were greyed out after clicking "OK". This was truly a bummer as I couldn't do what I wanted to try. So I looked though everything else and was happy with all the other info it gave.
Not wanting to sit in the garage I went upstairs and just went through all the items to see what else could be done. When clicking through the software, it told me that a GS-911 wasn't attached. I clicked OK, and could at least see all the menu items were. Well, oddly enough I went back to the ESA calibration and I got a message that said to connect the device. I just clicked OK and to my surprise the calibration buttons were not greyed out. I thought this was too good to be true, but immediately went down to the motorcycle and plugged it in with the GS-911. As soon as the computer recognized the device, I clicked on the rear calibration. Got another message, but I heard the ESA motor run! It cycled the shock all the way down and up. I couldn't believe it so I pressed it again, and I got an error message on the computer, but the shock cycled up and down. There were no calibration readouts on the program, but it cycled the shock, I essentially tricked the software past the message and allowed me to send the command top the bikes computer. I unplugged the GS-911 and started the bike. I cycled to the rider and luggage mode, and the display flashed and moved the shock! I now tried all the modes and the display flashed every time and set the shock.
I can't say how happy I am about this as I didn't want this to turn into the "You need a new rear shock". I will now always be careful and only set pre-load when the bike is unloaded.
For the developer, it would be very cool to add a function to the non-hall ESA owners that could just tell the bike to do whatever happened when I clicked the "calibrate rear shock" without it checking if it has the hall sensors. Put a warning message or whatever, but this has the potential to fix the 2 rider stuck shock issue.
Thanks!

Hi Andreas
Thanks for the feedback, really appreciate it.
While I had a suspicion that this will work even on non-HALL sensor ESA's we do not allow it because we want to first test that it works on our side before releasing it to the general public. So far we have not been able to source a bike with the old ESA sensors.
If you want to help us get this tested, please send us your logs and contact our helpdesk so I can send you test software.

HI!
After trying Andreas instructions me ESA does not work at all. Ans already can not even among comfort - normal - sport. Even when the ignition will not start self diagnosed dampers (not buzz)
:'( :'( :'(

Fantastic. How are you make anything? I find you first if I do it . How can I do?
-
So I try again this manual for the second time. The result? ESA again stopped working.

Good day!
I have a question for developers who are present in this forum, as the heldesk not help me !. Work is a version which is able to calibrate ESA chassis without HALL sensor ??? I bought a GS911 only for calibration rear shock. To this day, it does not work and I am very angry! You lie to customers. >:( >:( >:( >:( >:( >:( >:( >:( >:( >:( >:( >:( >:( >:(
Please reply

So. Firstly, I would like to apologize developers and forum administrator on hex.code for my very bad post ...
Calibrate as instructed by trickflow really works on models of without hall sensor. Calibration me not successful due to the gearbox jammed in the suspensions. After manual gearbox shake it possible to calibration run and even as instructed by trickflow.

Hello, this is my first post. I’m in the UK and have a recently acquired 2005 R1200RT, which is not currently on the road. I have a GS-911Blu and am on a learning curve, though I have already successfully carried out the pressure test following replacement of the brake fluid and corrected a non-working screen by simply running the calibration utility.
Could I ask for some guidance on the ESA 1 suspension, picking up on the previous post by trickflow?
The situation with my bike was the same as reported by trickflow: the instrument panel responded to the commands from the ESA button for damping and preload, but nothing seemed to be happening on the bike. Performing the manual suspension test described in the BMW repair manual confirmed this: no noticeable change in damper stiffness or rear ride height.
Selecting suspension calibration in the ZFE menu returns: “No ESA that can be calibrated is fitted to this motorcycle”. I understand that this is because the GS-911 does not currently support ESA 1 with potentiometer position sensor, but I used trickflow’s procedure to have the GS-911 software accept the presence of the ESA suspension (front and rear calibration commands no longer greyed out).
A few seconds after clicking on “Calibrate front suspension” an error message is displayed: “Negative response from controller: sub function not supported by controller or invalid format”.
A few seconds after clicking on “Calibrate rear suspension” an error message is displayed: “Front calibration stopped by user”.
The calibration page does warn that if calibration is interrupted, the ZFE will log a fault and disable changes to the ESA using the ESA button. I didn’t knowingly interrupt it, but this is indeed the current situation: there is now no response from the screen to the ESA switch for damping or preload – though there is no fault code visible.
I’ve tried repeating the procedure a few times, with the same result each time.
Durinkos seems to have sorted his by shaking the rear suspension unit. I’m not sure what he did, but in my case the unit is not jammed: applying 12 volts to the (disconnected) blue connector on the rear mudguard causes the rear suspension preload adjustment to motor up and down smoothly, so preload changes ought to work at least.
Does anyone have any ideas as to how I can at least restore the bike to its previous condition (display screen responding to the button) and preferably restore the suspension to working order?
The autoscan report is below. This does not list the ESA suspension but I have an earlier report from before I started looking at the suspension, which is the same; I don’t know whether or not this is not significant.
Thank you for any help you can offer.

Hello, good morning and welcome :)
There is a not registered ESA on ZFE-HighZFE type: ZFE-High .
This is the main unit for diagnosis over the CAN. Did you change this ZFE?
Think that is a dealers job, register this function to the ZFE online. Than you are
able to read this unit.

Thank you for your comments Schuppi.
I bought the bike from a friend, who had it from nearly new and did over 100,000 miles on it commuting to work. He never carried a passenger or varied the load and most of the running was in traffic on the motorway, so he would not have needed to change the ESA settings (I’m sure he would have played with it when he first had the bike though). He had latterly started to wonder if the ESA was working (How do you tell, he asked…) but did nothing about it apart from replacing the control switch, which was no longer positive in action. This made no difference, and anyway the screen always responded to the switch even though the system didn’t. I’m as sure as can be that the ZFE is the original one.
I’ve seen in the BMW repair manual that the BMW diagnostic tool includes a check on the ESA settings, so like you wonder whether this is going to be something for a dealer to do.
However, from the earlier posts, it seemed that Hexcode might be working on covering this early ESA system, so I’m still hoping for that.
-
Please, give it just another test.
As repair manual describes:
select toolbox ZFE!
select control the ESA suspension settings. Maybe it helps, otherwise
what about a picture of your ESA connectors to nsee the pins :)
-
Thank you for your continued interest Schuppi.
As I understand it, the repair manual refers to the use of a BMW diagnostic tool, which I don’t have and with the bike off the road for the moment, I won’t be able to organise for a while. A visit to my local BMW dealer will have to wait for later, if I can’t resolve the problem beforehand. I do normally do all jobs on my bikes myself though.
I’ll certainly try with the GS-911 again, but as it is a somewhat unauthorised procedure I’m using, I’m not too optimistic. It would be nice to have ESA 1 supported by the GS-911 software, but I suppose that with these bikes getting older, Hexcode have other priorities.
The 12V power connector to the rear suspension unit showed some light corrosion, which I carefully cleaned off and then protected with electrolube. I’ll have another look at the others.
I won’t have any spare time to do this until later this week though.
-
Try to connect the blue connector for 12V and spring set to be compressed to the maximum. Involve connector and then start the calibration. If that fails it's inversely (Springs) moves and start calibration again. It also does not help that he disassemble, inspect potentiometer or cable.

:)Great.
Thank you for sharing.

Hello durinkos.
I was hoping to hear from you, as you had managed to resolve the problem I now have. I’ll post again once I’ve had a chance to get back to the bike (later this week I hope).
Contrary to your suggestion I had placed the spring preload motor at the soft position, thinking that this would be the starting point. Anyway, I’ll try it at the other end of the range of movement and I’ll also pay particular attention to all connections, given the experience in the useful link you provided.
-
My problem of calibration could not be completed at that Gearboxes from the rear shock was hooked and he could not rewind motor. As shown in the picture 4 in my post fourth gear, I had to manually rotated. But as you're writing it's not your problem.

Hello again durinkos
I had a bit of time with the bike today. I put the rear suspension spring to the fully compressed position as you suggested, but this has not changed anything. I then tried the unofficial calibration with the GS-911 again, but the results are as before – same error messages. I’ve cleaned the connectors (again) and checked continuity from the ZFE to all of the connectors, front and rear – all OK. Powering the spring motor from an external 12V supply, I also checked the resistance at the potentiometer for different spring positions and this seems OK (resistance of between around 300 and 2200 ohms) so I’m satisfied that the spring preload adjustment works at the strut at least.
I don’t know how to measure or check the damper adjusters - they’re stepper motors I think.
With no official support for this early ESA in the GS-911, I think that I’ll have to take the bike to a BMW dealer for calibration with their diagnostic machine, though that won'y be for some time. If that fails, I may just abandon the ESA, either living with whatever damper settings I have and rigging up a switch under the seat for the rare occasions I need to adjust the preload, or buy non-ESA suspension units. The bike is old and does not justify the huge cost of even secondhand ESA parts.

Hello Schuppi
Interesting post: it confirms that the GS-911 does not support the potentiometer type ESA…
When I first got the bike there was one fault code:
“41769 Windscreen sensor / Front ESA sensor malfunction. The fault is currently present.”
The screen was not working, but I cleared the fault code and ran the screen calibration, after which the screen worked and the fault code had disappeared and has not been seen again since. An odd combination I thought: Windscreen sensor and Front ESA sensor malfunction
There is currently no fault code listed (well there is one for the fuel gauge sender, because the tank is off).
Thank you again for your trouble.

Hello again
I'm not sure whether the continuing story of my 2005 R1200RT's ESA properly belongs here, but I have been impressed by the interest shown so far.
So, I finally got the bike on the road and took it to my local BMW dealer. They reported that the bike "failed the ESA configuration". I allowed them an hour of diagnostic time, but they did not identify the cause of the problem - they wanted to dismantle the bike and suspected the ZFE. I'm always a bit suspicious of control units being condemned, and in any case was not prepared to go any further with them. The bike is of course, perfectly useable as it is. I don't know what damping setting I'm on (but I can live with it) and I can easily adjust the rear preload with a couple of wires if carrying my wife on the pillion.
However, I can't rule out that the ZFE might be faulty. Could anybody advise what the implications are of replacing the ZFE with second-hand one of the same type (mine is a "High"):
- where are the VIN and the mileage stored? In the ZFE or in the instrument panel?
- does a ZFE configure itself (in the way a PC identifies what it is connected to) or would this be a job for a BMW dealer again?
Thank you far any advice you can give me.

I know that this post is now quite old, but it does have a lot of relevant information for someone that is experiencing ESA problems. I too have been suffering them on my 2007 K1200R. When I first purchased the bike the ESA button functioned as normal and the stepper motors on the front and rear all worked as they should do. The only thing that did not work was the preload adjuster. I went to CW Motors of Dorchester and they advised me that sometimes the rear ESA preload jams but you can apply 12volts directly to the blue connector and sometimes get things moving again. Following this you will need to have the device calibrated. I went away and did as they suggested and the ESA preload would go through the routine fine. I then got in touch with someone who had a GS-911 and asked them if they would calibrate the ESA. He was aware that the software was not designed for the ESA with potentiometers (just Hall Effect type) but was prepared to give it a go by doing as Trickflow has suggested.
After trying the routine several times we conceded that it wasn't going to be fixed. What I hadn't anticipated was that after connecting and running the routine my ESA button and associated display Icons had completely malfunctioned.
The purpose of my post was to give everyone the background to my problem and then some information that I was given when I returned to CW of Dorchester to get them to try and calibrated the ESA.
CW tried the calibration but their diagnostic system reported that there was a wiring issue. It wasn't very specific and as such CW recommended that I book the bike in for further checks. Like so many other owners I did not want to rack up a bill only to find that this was going to cost a fortune to fix. CW were quite understanding so I asked asked them what I could do as far as second hand replacements were concerned, i.e. if I had to replace the ZFE. They advised that in the past they would be able to connect to the BMW diagnotics and reconfigure the unit to run, however the situation has now changed such that BMW will not allow a second hand control board to be fitted. CE also advised that if anyone does this then there is a possibility that the unit will work fine providing all else is okay, but should be aware there are consequences. If you take your bike and subsequently plug it into the BMW diagnostic system it will render the control board inactive. There was also an indication that other boards could be affected in that the diagnostic system would write a new serial number to other boards and that they too would be rendered inoperative. This all sounded so outrageous to me but thought that perhaps BMW might justify this by saying it stops people stealing bikes to sell the parts. Whatever the reason, it has given me the incentive to buy a ZZR1400. I still have not given up on the K1200R, but am really frustrated that BMW's cost so much to maintain, and compared to my experience of Japanese bikes BMW are far more unreliable.
-
I gave up with the ESA, not wanting to waste any more money on the problem. I bought a pair of second-hand non-ESA suspension units in lovely condition and at reasonable cost and removed the ESA switch from the handlebars. I'm perfectly happy with the bike as it is. Would I like to have working ESA, well yes, but not at any price on a 10-year old bike.
