Hi All,

The car is a 2010 BMW 750ix, with an MSD85 ECU. I bought a new battery into it, which is an Exide 95Ah AGM type, and although I tried to register the battery, it resulted with D6121_00000000_01_301 diagcode and a note "Action failed on account of unfulfilled interdepencies".
What did I fucked big time? And if there is no "95AH AGM" option to choose at the registration, but only "105Ah AGM" and "90Ah", which one should I choose?

Since then there are rough gearshifts sometimes, but after restart it's gone. No oil level indication on the CIC, though with ICOM I can check the level.

The following codes appeared besides:

E5850F Message (data, drive train 2, 0x3F9) incorrect, receiver FRM, transmitter DME/DDE

Did anybody experienced these sympthomes?

Do I have to reprogram the ECU? If yes, how should I start to that? What to backup, where to get a complete ECU and other stuff for my car?

I have an OEM ICOM NEXT (fw updated), but not registered ISTA+ and ISTA/P. Can it cause any problems?

Thanks for your help in advance.

For your faults but here on forum you have latest ista standalone and everithing you need..It can not cose problems..than made diag on all modules and check fuses..good luck

Program the car with ista p which you can find here. Use the loader for making it work with your icom next. After that check if any faults are present.

When putting in battery is that size always choose closes under. For example. 98ah = 90
