Central Vehicle Electronics/ZFE/GM issues / Re: HELP - Mileage discrepancy...

@miguelmpn  You can take your bike in to your friendly BMW dealer and have them code the new cluster with the correct mileage.  Note that they can only "upwrite" (apparently a BMW expression) and cannot "downwrite".  I.e. they can only add mileage to the new cluster, not lower it.

So, if your original cluster showed 40000km, and the new one shows 35000km, they can add the 5000km to the mileage display and match the DME.

If your new cluster shows 50000km, they cannot lower the mileage to 40000km.

This can also not be done with the GS911.

Good to see your commonsense post Jughead, the volume of the K7 dashes requiring repair due age has increased, did 3 repairs last week & another on its way, was not aware full recoding was possible on the dash assemblies

Alright, it seems we are deviating from my original statement, which was about an F700GS.

The cluster isn't original to the motorcycle. The original was damaged in the accident. I went in an ambulance, and obviously, no one picked up the pieces on the ground.
Later, I was advised to send the motorcycle to the dealer and pay much more than the bike was worth, so I repaired it myself and did a good job, except for the discrepancy error in the cluster that makes the Kms blink.

To replace the missing cluster, I decided to buy a second one from a motorcycle of the same year. This means that the VIN is different, and it has less Kms than the ECU. My plan was to add kms in the cluster until it reaches the ECU mileage. It works well in analogue clusters, but that does not seem possible here, that is what I wanted to know.

No my last post was to directly address your situation & others who fit another dash from a different VIN

You did not originally mention you had recovered your original dash & had it working again other than the flashig ODO

The dash backs up the ODO value usually held in BMSKP (on the F800/R1200's), the BMW Dealer ISTA/AOS system has a routine to resynch the master & backup ODO values, it is a simple routine done quickly

I deal with that every time I do a K7 dash repair, when I put a dash for repair on my test bench system which of corse has a non matching BMSKP I have flashing of ODO,, I do the dash repair, test & confirm all OK then clear fault codes, the dash goes back to the owner & since both ECU's have the same ODO valuw no action is needed, if the owner had done any riding without the dash then they have to go to a Dealer to resync the values

One owner with a different model has 2 Engine ECU's & if he swaps between them & does riding on the otherr Engine ECU he then has to have a mate at a Dealer resync the unused ECU with the higher value in the dash

In your case the VIN & Vehicle Order may also come into play, I asked you to get the Info from Autoscan to look at the VO engine ECU info so I could look into it but you did not post the info

GS-911 Wifi / (Better?) Instructions for usi...

Last post by JRWooden - May 11, 2026, 07:49:55 PM

I have the Hex GS-911 user manual dated 3/26  -  Edition 17
Either I missed it or the latest enhancements for using a WiFi 911 w/ an iphone including hotspot doesn't seem to be covered completely...

Is there a separate document?
Did I miss it somehow?
or do I just need to be more patient with the technical writer?   ;)

Thanks,
Jim

€80 is very cheap for a diagnostics session at a main dealership for any manufacturer, on a merc in the UK std free is over €300

its more about the cost of the work booking it beforehand, then saying hello on the day and filling out paperwork (and charging for work done at pick up), then the tech taking 10 mins to find and get in the workshop, and then plugging it in to talk to base to see what muddle up the bike is in - altogether that'll be 30 mins chargeable labour easily - and the rental on the dealer online diagnostic equipment on a Merc is €12000 a year ongoing - I expect a BMW dealer won't be charged much less to lease the equipment

I can see a number of pitfalls

1) the VIN listed in the cluster unit now on your bike isn't likely to be your bikes original VIN so BMW systems will bulk at any further work - unless someone has helped you sort this - its all doable just not easy and most don't have the kit.  No idea how on the TFT cluster from 2017 to 2024, but I bet its doable. (note: this is not case on newer 2025 model year bikes, they have a new setup stopping play)

2) it maybe that HEX have done some work that maybe give insights on both the VIN change and the Mileage issue - worth asking the question

3) maybe you are unaware - the TFT clusters have been full of quite buggy software and a number of minor issues, and with user weirdness and features not behaving - there is about 10 cluster software updates that say a 2018 bike hasn't got vs an up to date 2024 unit has

so if the VIN inside the unit is OK it likely needs an update and you could come out in a good place....

Way too much irrelevant info & misinformation better to comment on individual issues when the subject is known & answers are relevant clearly not in this case

With the K7 CAN dashes VIN, VO & ODO values are all stored in Dash & BMSKP with the dash acting as backup, the EEPROM in the dashes has been determined by others to be read only for VIN & ODO at a minimum & it is labelled as Mfr of BMW so is custom for them to prevent 3rd party EEPROM Reader/Writers being used to change content, I can think of one owner who went to the extent of desolder of the EEPROM & resolder on an other pcb

There has been no volume of requests to look further into reprogramming of the K7 dashes, repairs however due ageing there are many requests, completed 3 this week alone & another arriving next week

The "the TFT clusters have been full of quite buggy software" TFT display is merely a display firmware is specific to the model/year of the bike & for the K7 dash consists of one updatable firmware file for all the dash functions so to lump all year model issues together is rubbish, the dash firmware including the LCD display on the K7 is good & stable

Yes, that's what I thought as well...

I had an accident and had to buy a replacement cluster.
I bought a used one, because the new ones include the ECU and more, and I would have to ship the motorcycle to Lisbon. (At the time, we did not have a dealer in Madeira Island) I installed and it works normally, just the distance blinks due to the error.

Now rwe have a Motorrad dealership with motorshop, so I went there to ask if they could solve it. They said they have no clue, and I would have to pay 80€ just to investigate.
So I left without asking them to do anything... and was trying to find another way, but the motorcycle is drivable, makes no difference other than knowing the error is there.

Just as a curiosity, I asked them how much for a service. They budgeted 600€. (thank god I've been doing them myself for over 20k kms, and even fixed the motorcycle after the accident)

Great, thanks! Will check the connections and potentially replace it
