Bimmerutility not working - need mapping update

I can no longer code certain modules in BU. Anyone else experienced this?


I have a 2020 M340ix and I had the gearshift console replaced by the dealer due to the EPB not working.

They did a full update of all the s/w. I don't do any updates (even have the SIM disabled) as I am tuned. But I let them do the updates this time.

To my pleasant surprise the DME was not re-locked, so I reflashed MHD (it did a long flash) and I am back. Anyway this is a side point.

I went to program everything back to how I had it. I started with Bimmercode and did a lot of the basic coding there - no issue.

Then I went to Bimmerutility to code the more complex items. That did not work.

Using Android app - it kept crashing every time I'd try to do a backup. So I moved to Windows with an enet, and that too did not work.

I could not code certain modules - ACSM5 or DSC modules would not allow me to code - BUT BDC was fine.

I contacted BimmerUtility and they confirmed that BMW have changed the mappings and they need to make an update for it to work again.

So I am waiting on the update in order to complete my coding.

Anyone else on the latest update noticed this?
