Hi guys
--------
This was resolved. Solution posted further down the thread.
--------
Long time user first time poster.
Yesterday when I got in my car and turned it on I got an error on the dash "Instrument Cluster Error. Please visit workshop". It then leaves an orange [!] light and the word 'Error' where the trip milage displays, and I have also got a "Front assist unavailable" error which I assume is linked. Otherwise the car and dashboard seems to function and drive fine.
Video here of the error:
The code doesn't clear on OBDeleven, and there is very little information on the internet about the error. I have messaged that company in the video to see if they can share some insight.
Has anyone come across this error or can share any thoughts or insight?
Thank you!

Post-up a copy of the SCAN report for this car so we can see the exact error details. Also, has there been any coding changes made to this car lately? Go to History and then follow the instructions below. After you receive the email that you sent to yourself from the last screenshot below - copy and paste the contents in a new post:

Hi Don,
See below for full scan. It's the virtual cockpit code and the ACC code which are the issues. I don't believe the other codes are related, they seem to be intermittent.
There was no coding or adaptations done immediately prior to this error appearing. The last thing I did was maybe two days prior where I changed some radio text and frequency settings for module 5F (radio).
But my thoughts were the same, it almost seems like there is some sort of coding error, but I don't think what I changed has any link to this. I will post the adaption log below.

Here is the adaption log. Last thing changed was to module 5F on the 5th September, this virtual cockpit error occurred on the 9th. So I don't think it's related.

hmm.........Dashboard error looks odd (and concerning). Here are the salient aspects of the fault (from my perspective): - Date of SCAN = 2023-09-09 20:11:06.
- Date of Dashboard error = 2023-09-06 16:57:35.
- Malfunction frequency counter =1
These points mean that notwithstanding that the error was "static" when first registered - in the 3 x day period from when the fault was first registered to the date of the SCAN - the same error has NOT been re-registered on a subsequent ignition cycle (I assume that the car was used in this period). Normally this fault-code is accompanied by a "check sum error" descriptor - not sure why this is absent on your car!
There are Technical Service Bulletins about this fault code on Dasgboard modules the say that the cause is over-sensitive response to the diagnostic device (dealer's ODIS device) -see HERE and HERE But I can't find a TSB with your part number.

Ah yes you're right on the date of error vs. date of scan. Yes the car was used on all days in between.
I thought the same thing, it seems to have only logged it once. But it cannot be cleared.
I too found that TSB release, for Audi, doesn't seem to be any from VW (that are easily found online anyway). I will send this info to the local dealer and see if they have any knowledge of the error or any sort of software update available for the virtual cockpit unit.
I haven't heard back from that company who posted the Youtube video as of yet.
Any other thoughts from your technical perspective/background Don?

Alas no "other thoughts"! I'm also not sure about the ACC error - it seems that 2023-09-06 was a pivotal date for this car. The ACC error happened about 30 minutes after the Dashboard module error and it generated the mating error on the Engine module. Interestingly, the fault frequency counter for the ACC error is ONE, but the Engine fault is SIX.
My only suggestion is that you contact a dealer and ask if there has been a similar TSB for this dashboard module. Hopefully the answer is yes and the problem can be fixed simply by a software patch.

Thanks for your help thus far. I’m talking with VW currently, as well as some gurus in our local VW club. VW’s indication is the cluster needs to be replaced….
I’m also liaising with a couple of VAG coding companies in Europe.
I will update this thread once I have the problem fixed. It seems like a software issue, so surely the answer can’t be throwing away the physical unit and replacing it. But we’ll see.

Well I have a great update to share - after a lot of research I managed to find the solution to this, and have successfully removed the error on my vehicle. I continued to drive the car around with the error present while I was trying to still find a solution. It took me a few days to realise that there were no chimes anymore. Indicators, seatbelt warnings, etc. So I started to suspect that there was some sort of failure with the speaker. I started googling virtual cockpit speaker replacement, and finally stumbled upon the solution! This mini tools article confirmed my suspicion, and they sell a replacement speaker. Article hereReplacement speaker here
The speaker arrived promptly via DHL, it's plug and play, no soldering, and bingo - all errors gone! Including the ACC error. VW's solution was replace the cluster at anywhere from $1,500-6,500 depending on if a used or new one was sourced. So am happy to have solved it for $100. Hopefully this thread is helpful for anyone else that suffers the same problem. |

coons88 : Well done!! This is a new learning for me - thanks for sharing your information. I suspect that the most difficult part of the repair was removing the cluster from the dashboard!!

You’re not wrong - that was indeed the hardest part, it’s clipped in there pretty well!
I also read somewhere that the fan in the unit can also fail and cause a similar error.

thank your for your post and links. after over a year with this issue on my passat b8 i finally managed to fix it.
i can confirm issue was speaker. Minitools shipped it and delivered speaker within 5 days using dhl. 20 min of work and everything working fine again. blinker and warning sounds back, acc error gone, everything working fine...
easy fix, and much cheaper than changing compete virtual cockpit.
-Thank you

I had the same problem, thanks to your tutorial I fixed it just like you did. But the static error B200041 remained and cannot be deleted. Otherwise everything works. How did you deal with it?

blacster : Hi. So, here's the thing - the accompanying words for the B200041 fault is " Ctrl. module faulty". This means that this is a general, catch-all error (i.e. it's not specific to just the speaker replacement issue in coons88 response).
If you have correctly replaced the speaker and the fault won't delete, it clearly means that the error is elsewhere - maybe the module memory is faulty. or perhaps there is a CRC error (I'm guessing, of course).
Are there any other fault codes on this car? Has the fault appeared following any work to this vehicle - equipment retrofit maybe? Has there been any dataset updates to the hex17 module, or any other coding changes? Does this fault have a back-story?

I had exactly the same problem as above. The car stopped making sounds from the alarm clocks, this turned off all the assistants and a yellow triangle appeared on the display. After replacing the speaker, the exclamation mark immediately disappeared and all assistants activated. The car is otherwise faultless and works as it should. Only error B200041 remained in the display and it cannot be deleted.
