Hi, sorry, I never got the info on how to do this...just got used to the error popping up and disappearing again. Cheers, Phil

I went from 0276 and navigation continued to work with no issues. Cheers Phil

I've sent this via PM, thanks.

I'm getting an intermittent SOS warning error on the dashboard (which clears almost immediately), with the overhead SOS light also turning red (which clears itself after an engine restart). I read on another thread that updating the OCU had fixed this for somebody.

Yes, that is what my OBD scanner app shows me "OCU3_5WA035284B_", so I guess I just need to find the latest version for that hardware? I'm not going to lie, this is getting a bit confusing 😕

But which version of the firmware should I be using?

Hi @Cairus , thanks for your input. I'm more confused about which software I'm supposed to be using based on that table. Which one should I be using? Also, is it a simple case of extracting to a USBC stick and running the update from the service mode (like I did for my MIB3 updates) or are there other tasks to do too? Many thanks

Hi @GiscoYeti , yes I can open that link, but the OCU software in there looks to be the non "B" version software OCU3_5WA035284__. I need OCU3_5WA035284B_

Hi @Cairus , not sure if I can receive PMs yet as I'm fairly new to the forums.

I've not been able to locate the file required. It looks like mibsolution.one is permanently down ☹️ Does anyone know a good source for the lastest version (1.43?) for OCU3_5WA035284B_ ? Thanks

Hi, I recently updated my MIB3 software to 0332. Since doing this, I've been getting the dreaded SOS warning message pop up (which clears almost immediately afterwards with the general warning then clearing when stopping/starting the car). Do I need to also update my OCU software, could this be the issue? I'm currently on 0139 but I believe there is at least a 0143 version available. My OCU is listed as OCU3_5WA035284B_ Many thanks for any help. Phil

No, nothing else required. I personally did reset the code using a recommended OBDII scanner and free android app, but everything worked as expected before it was reset anyway - you don't get any errors/messages if you leave the code. Phil

A quick update...with a new USB stick formatted as FAT32 I've completed the two upgrades to 308, then 332 without a problem. Many thanks for all your help in getting this sorted Lee, really appreciate it. Phil

Looks like my USB stick might be screwy, as I'm now getting errors copying files across and it won't delete the existing partition. Time to get another stick.

I'll try fat32, and maybe create a smaller partition just in case it doesn't like the 64GB size.
