Hello,

I am providing a service to a customer who has an F10 BMW 528i and damaged his MEVD1729 DME by failed attempt at opening the case, the DME multilayer PCB is destroyed and I cannot recover the ISN or clone the DME like normal.
He has provided his CAS4+ module and key, and the biggest problem is CAS4+ cannot be decrypted without DME ISN to perform ISN transfer to donor DME.
Autohex support has suggested that I could set the DME and CAS4+ ISN to all 0's and it will randomize the ISN and then new keys will need to be programmed.

Before I proceed with this I wanted to ensure that I can program this customers DME on the bench, I am aware that flexray is required and I have a ZGW module to use but need to figure out the correct connection diagram to make it work.
Are any other modules needing to be added to the setup? I have read that DSC module is needed to be able to see the DME as it has the terminating resistor for the flexray system in it? I have an F10 DSC module on hand to use if so.

Any assistance or connection diagrams Autohex or other helpful members could supply I would be very grateful!

If you match DME and CAS isn by unlocking cas by 32 zeros (0000...). Then you may have to reset egs also to match isn as DME-CAS.
It is possible to connect CAS-ZGW and DME together with flexray connection and program dme from indiv programming to adapt vin. DME isn can be read from onbench--->factory mode isn option connecting DME alone in Autohex.
Please check the given wiring for CAS-ZGW with flexray wiring and dme pinout with flexray.

OK Guys I successfully made the bench connection and made better diagrams to use that are less confusing, and no DSC module was required to terminate flexray and make DME visible as I had previously read.  CAS4 ZGW DME FLEXRAY.png You have insufficient rights to see the content. MEVD17.2.9 AND ZGW-FEM ON BENCH AUTOHEX.png You have insufficient rights to see the content.

I tried to open your diagram and also posted my own updated version but its impossible to read, how can I correct this so that other people can use the diagram I made?
