Hello,

is there a possibilty to find out a loose Zusb from DCT in OEM car version?

I've loose it and need it important to flash the right DCT with Winkpft.

Thanks

Hello Jaque,

is this IS-Flash or OEM-Software for series cars?

8606072 is for normal 135 n55 dct not 335is

What is a "loose zusb"? I'm super curious for some context here.

The above are numbers used to identify the software version used on BMW modules.

The OP appears to be asking what the OEM one is for the module which controls the DCT gearbox, as he has 'lost' it which I'm guessing means not sure what it is.

Software is generally model/variant/gearbox specific (the version for the DCT differs to that of the AT for example) but, for some different models with DCTs, is interchangeable. With the right software (which can be downloaded for free) and knowledge of the process (how to use WinKFP) can be done 'at home'. The thread linked below provides further details of some different Zusb options:

Thank you! I've used WinKFP for PPK and INPA for valvetronic re learning after replacement.

That's awesome further ECU modifying and investigating continues! I'll have to see if my DCT might benefit from a flash for the DKG for higher pressure/tighter engagement.

Just watch the number of DCT flashes available if UIF is enabled. It's quite low for DCTs so you may want to disable this option whilst experimenting and re-enable for the final flash so a record is created.
