Were do I find the fault codes

[short cut]

Were do I look up the fault codes. I have a 41768 rear sensor
malfunction. Is ther another web site I need to go to?

you should not do as you handle implies... I assume the faultcode would actually read: "Rear ESA sensor malfunction"

Rule 3 also applies...  http://www.hexcode.co.za/products/gs-911/support-forum-rules

then sit back and think about this for a while... ESA sensor malfunction... (ESA= Electronic Suspension Adjustment)

The ZFE thinks/knows it has an issue with the sensor that determines the ESA position - the ESA is integrated into your rear shock...

I would like more info on how to check this sensor, and how to change
it if it is bad.

While I don't work for Hexcode, unfortunately, the reality is that the GS-911 (and this board) stop at the point of actually telling you how to repair any given failure. This board's purpose appears to be to provide help with using the GS-911 itself, but it's a slippery slope from there to figuring what to actually do about the information that it provides... At the end of the day, the GS-911 is just another tool to tell you what the bike thinks is wrong with itself, but it doesn't go as far as telling you how to fix anything that might actually be wrong beyond relatively trivial and obvious sorts of failures. Once it's told you what to look at, I think there is a certain assumption that you have access to repair manuals and appropriate tools, and whatever other skills and resources you will need to complete the diagnosis and repair, and determine the actual underlying cause of the error code.

In this case, it could be anything from a loose connector to faulty wiring to a bad sensor. I think the rear ESA shock has a hall effect sensor. My understanding is that the ESA shocks are treated by BMW as a whole unit (the dealers will not repair just a sensor in an ESA shock, they'll replace the whole thing.) They're also unfortunately ludicrously expensive to replace - several thousand dollars for a new one. And replacing one requires the GT1 unit (that only the dealers have) in order to tell the central bike computer how to talk to the new shock. So trying to repair the electronics yourself is probably entering some uncharted territory.

There are a couple of places in the U.S. who are doing a business by replacing the shock portion with higher quality units (much cheaper than a new ESA shock), and grafting the existing electronic part onto the new shock, but obviously the electronics have to be in working order for that to be a viable option.

I think your best hope at this point may be getting it fixed under warranty, if applicable, or at least having a dealer run the further tests on the ESA unit that the GT1 can evidently do.

Thanks for the info, does not sound good. I'll have to see if there is
away to just fix the sensor. If not I'll have to live with it for
awhile.

that is correct.. GS-911 is a tool... having it enables you to read the fault memory of the ECU's, helps you identify issues, and perform other related and needed functions and tests that you couldn't without the tool... however, it most certainly is NOT a repair service, and neither was it ever advertised as one...  ...however, in most cases we try and help, but that is by no means a guarantee nor should it be expected...  - I think many of you have received many times more in terms of our time, than you ever paid for the GS-911... ;-)

The group description states: "An information exchange for users of the GS-911 diagnostic tool for BMW motorcycles. The topic is strictly BMW motorcycle computer diagnostics and related fault finding and repair procedures. Please read the List Rules: http://www.hexcode.co.za/products/gs-911 /support-forum-rules"

The idea being that users can interact and share information and repair help amongst one another...

best,
Stephan
