Firstly an apology, this is my first post and its long as I want to tell you my fault finding methedology.

I have been chasing an intermittent fault on my MMI for several months now.
The car is an Audi RS4 B9 (2018) with 86,000 miles on it.
The MMI is a navigation plus (I8H) with Bang & Olufsen which I connect my iPhone to via the USB cable in the front panel.
The fault started out as the radio (DAB) taking several seconds (45 plus) to come on to station, previously
it was as soon as the car started (occasionally it still does).
Several weeks later this morphed into the whole MMI booting up as normal and then after a while switching itself off
(no MMI button controls, volume etc from the central console or steering wheel), only to start rebooting again and again
numerous times until it finally gives up and swithces itself off.
Other times it boots up and works perfectly until you stop the car to fuel up for example and then it will start the
reboot cycle as above and refuse to work.

After scanning the car and tracing the MOST optical loop its as follows:
Information electronics control unit 1 (J794), to Control unit in instrument cluster (J285),
to Digital sound package control unit (J525), back around to Information electronics control unit 1 (J794)

First scan results

[Optical data bus: sporadic open circuit in instrument cluster display]
Intermittent - Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Status: 00000001
Fault Priority: 7
Fault Frequency: 1
Reset counter: 250
Mileage: 111064 km
Date: 2023.02.19
Time: 14:37:31

Voltage terminal 30: 13.1 V
Temperature of MOST transceiver-max.value: -50 �C
Temperature of MOST transceiver-min.value: -11 �C
Temperature of MOST transceiver-Up-to-date: 31 �C

Before anyone says, yes I have tried the Optical Bus Diagnostic and it reports that it isn't available!
I assume this is because the CAN Gateway doesn't have a MOST optical connector in it.
I hav elso pulled out and looked at all the MOST connectors and there is a red light present on all of them.

I have removed, stripped and checked both the J794 & J285 for dry joints, corrosion etc, with nothing found.
These parts are not cheap to buy, even second hand just to test a theory, plus the CP will kick in I'm sure.

So I opted for the cheapest route and started with the optical cables looking for kinks that might be causing data loss.
One at a time I unplugged the original optical cables and replaced them with run around cables.
This didn't cure the fault, so its not an optical cable fault, its down to a module.

Next I optically looped out the instrument cluster.
It then reported the instrument cluster lost communication, which makes sense and now sporadic open circuit with the digital sound package module.
So the Information control unit now thinks the digital sound package module is faulty.
Next I reconnected the instrument cluster and looped out the digital sound package module.
This then reported sporadic open circuit with the instrument cluster again and lost communication with the digital sound package module.

So depending on which of either instrument or sound modules you have looped in, the optical loop says its sporadic open circuit.
These results leads me to thinking the likelyhood of both instrument and sound modules having the same fault is less likely than the
information electronics control unit actually being faulty.

I would welcome any ideas / comments on your views.

I think and it sounds like you have done all that you could do ; the Component Protection certainly limits you diagnosis. Any water damage history?

Address 17: Instruments seems to be a Red flag! And this fault in Address 19 as well:

1 Fault Found:
131699 - Control unit for information electronics 1
U1054 00 [00001000] - No Communication
[Timeout_Node_0x73_DiagAdress_5F_ZR_High]

I suppose you could remove and disconnect and inspect (all in sight!) the instrument cluster harness(es) as there may be a loose or corroded connection (???). Other than that, this all may be a mute point as even if you determine a bad component, it would be a dealer visit to correct or adapt it.


Edit: see if you can get a Auto-Scan when the MMI is up and running (when car is running) and see if any of those faults go away; especially the "no coms" .
