If ESP is not in SVT, then there will be no connection with it, because the bus flexray is not initialized.
Firstly need the correct SVT record. Second - learn flexray.

why should it not be in SVT? I think the Topicstarter knows how to change a FEM. But do not know how to properly verify the wires smile

According to the first message, it looks very similar.

RE: BMW F20 EPS no see in esys
I also have such a case of BMW G12 740i,
with DSC,
the car sees DSC and does not report a fault, but it is not visible to the ISTA, ESYS, INPA, etc. software
I have already had such cases (DME/DDE, DSC, etc.), usually it is enough to program the GW gate with the latest psdzdata
and flexray modules are back
or open the channels in tool32 and reprogram the GW gateway
but now it doesn't help...
and everything is OK for the car
If my post helped you hit the thanks and reputation button!under
