hi
I have a 2018 x6 3.0D and it has thrown that DTMF code now 3 times, two in comfort mode going going up a small hill slowly and once in sport mode going up a step windy curvy road at a brisk pace. All cases went into limp mode which allows about 6mph with a lot of shaking. so I shut it off and waited 5 min then restarted and was fine again.

but I am worried what this could be. sadly I did an upgrade using Esys to the HU and Nav and lost the prior error codes. only faults it has now is the rear defrost connector and a mirror auto dimmer malfunction.

Can't be plugs or coil packs (diesel) and seems like the transmission started downshifting then upshifting like it was confused before the chime and screen came on.

anyone with diesels solve this. I will wait until it happens again but I also see many updates to trans ECU and xdrive as well as the main motor ECU available since istep version 18-03-520, also thought about doing a regen on the DPF. car has only 24,000 miles (40,000kms). thoughts?

edit: the code it throws is a DDE code 276400 internal fault. that's it?

thanks
