ISTA/P Replace TRSVC ECU

I have installed ISTA/P and did the measures plan. The plan says that TRSVC ECU needs to be replaced and I'm trying to figure out why.

I have retrofitted the TRSVC ECU for Surround View but for now only rear-view camera is installed. ISTA/D says that the ECU has faulty memory because the other cameras are not installed. The rear-view camera is working properly and I have no issues with it.

The ECU production date is a year newer than the rest of the ECUs, not sure if it matters. When I installed the ECU I have upgraded its firmware version to match the car's I-step (2.53.4).

Will ISTA/P reject the SW update if I don't remove the TRSVC?

Is it better to do the full sw update with ISTA/P-ENET-ICOM SW Emulator or E-Sys-ENET?

Add other cameras to FA and try again to calculate measures plan.

I was thinking about it, but probably I'll get some camera malfunction messages on the iDrive screen.

So, before visiting the dealer, I'll have to unplug the fuse for the ECU.

You must also remove the camera from FA, if youbare visiting the dealer. If you wan to flash it with ISTA/P, then you must have all cameras in FA, so the module matches the FA. You can remove top view etc afterwards.

I think I got everything now Thank you!

BTW, Is it safe to use ISTA/P with ENET & ICOM sw emulator to flash the whole vehicle, or is it maybe wiser to use E-SYS with native ENET support?

I would use e-sys, but it requires some homework before you can flash retrofitted modules. So if the TRSVC does not really require update, just flash all factory modules with esys and you should be fine.
