ColorMFA

I recently installed ColorMFA on my A4 B7 and is currently running latest firmware, b31. After I finished setting everything up on it, I did a full scan with VCDS (original interface) and noticed this error on some modules (08-Auto HVAC and 18-Parking Heater, 46-Central Convenience):
01317 - Control Module in Instrument Cluster (J285)
49-00 No Communications
According to ross-tech wiki it has to do with the can-bus wiring, but what can the problem be here? everything works how it should on the ColorMFA, except for NAVI, but I have audio data, which means info can is working, car shows every door opening/closing, which means convenience can is working, motor-can I believe it's working, since I have all other info available. NAVI works fine with original cluster and no errors of no communications on it.

Since is not intermittent, it won't clear. I didn't had this errors prior to installing ColorMFA. Can this be because I've coded the cluster to "Highline without DIS" (I didn't touch the setting referring to "Level 1, 2") in order to deactivate the control of original screen? Or is it anything else I should set on ColorMFA?
I have WEBASTO as well and it won't work via remote if it has fault codes stored. I need to fix these errors somehow.

I also have factory fitted RNS-E navi and it does't show up when I plan a route and start the guidance. No green "NAVI" text. Any settings I should tweak for this inside Debug area to get it to work? I'll wait for your advices. Thank you!

Later edit: After I studied the CAN BUS wiring diagram for my car, I noticed these modules are all connected to the same CAN (convenience), so I assume it has something to do with CAN resistance, maybe. I will scan all other modules connected to convenience CAN and see if it logs the same error or just these 3 modules are affected, but so far I only noticed it on the above mentioned modules.

Check all wires connected from ColorMFA to cluster. Short circuit to adjacent wires, bad soldering, e.t.c. Check cluster connectors. Must be right connected to cluster. In ColorMFA firmware check data in CAN-monitor. Separately by each CAN (set checkbox only for Motor-CAN -> See data, set checkbox only for Comfort-CAN -> see data, set checkbox only for Info-CAN -> see data). In hidden settings take photo of Debug->Hardware->CAN Status and put it here.

I did do a double check of all connections before I put it in the car, nothing was wrong. All info is working, nothing is suspicious, but I will check all connections again. Here is the photo of CAN status in Debug and I will check each CAN separately, as you said. What about the navi not working? NAVI not working with ColorMFA

You installed ColorMFA to not your original cluster... But you changed coding in this cluster for supporting Navi ?

Yes. I copied all coding and features from my original cluster. I will check these again too, maybe I mistyped some number somewhere. I now finished checking all connections on board again and seems all are fine. I used a multimeter to make sure each wire goes where it should on the ColorMFA board. Here are some pictures: https://photos.app.goo.gl/Unv4PatB6HeAQBCUA
I will go to the car now and check CAN monitors and update the album with pictures.

What coding is set in adaptation channels 60, 61 and 62 ?

Check the photos album again. I’ve added photos with the codings and can monitors. For some reason, after I did the codings again, the errors changed to intermittent. I’ve cleared them and so far so good, but navi still not working.

After change coding need to send the cluster to "sleep".
Turn ignition Off and close car (with key or remote) for 10-15min. And check again.
Also check Navigation settings in ColorMFA menu. Navi must be enabled.

Navigation is enabled from menu. In Debug it should be Audi color, Audi master or both checked? Will check later for errors and report back.

Do not change settings in Debug menu.
This options only for NOT Audi cars. Uncheck both.

It was checked Audi color when I first checked. I will uncheck both.

I got rid of the errors for now and, hopefully, they won't come back. I also managed to get the navi screen to show by chosing from the menu "Show immediately", but if I exit the navi screen I can't go back to it because the green 'navi' text shows for a split second and disappears and nothing happens if I long press reset. If I enter the menu and exit out, the green navi text shows up again for a split second and goes away. Is this a bug?
Check this video.

About WEBASTO... Can you now look for info about it on CAN if I use the remote to turn it on and off?

Set correct coding in adaptation channel 19. As described in installation manual.

I know how to control webasto via CAN-bus on A48E. But there is a conflict with the cluster, if use control from ColorMFA.

The coding is set according to instructions: 1-Highline without DIS. Should I also set 0 to Level 1 and 2 setting?

About WEBASTO: What if we code the cluster there is no webasto installed, can u still control it, without conflicts?
Later edit:
Not working, coding is correct.

Later edit2: I also found a bug with the average speed. I took a quick 10 km ride and drove with speeds above 100km/h for more thank half of the trip, then came back home and stopped. The average speed shows 12km/h. This can't be accurate. Take a look at this video: https://photos.app.goo.gl/kzWhXZL51yPQgRPk8

You were unlucky. In A4B7 presents some clusters where not possible to disable original screen functions via coding. If not possible to disable this functions is also not possible normal usage of navi in ColorMFA screen. Because on each press to "reset" original screen switch between original screen data (does not matter what you removed this screen) and stop navigation show/update.

Does not fully functional if remove coding in cluster.

Average speed works as expected.

Before I install ColorMFA I tested what that coding does on that cluster and it did disable the up/down/reset combination buttons. Nothing happened on the screen when I put the coding for 'Highline without DIS'. So average speed adds the speed 0 to calculation when you're idleing? Is this the normal function for the original as well? Because I don't remember if I saw it working like this. If this is the case, then it's all good, except navi I will try in the near future to swap the ColorMFA to a color cluster and see how it behaves. Maybe, until then, you can push an update about that english thing I did, only what you find is suitable. The webasto I'm guessing it won't work as I said, because it will log an error it can't communicate with the cluster and it won't start even if ColorMFA can control it, so more research about this is needed. Thank you!
