Hi!

I have updated whole car using ISTA and 4.46.51 SDP but it didn't flash DSC and ISTA marked it with red X in Test Plan. Now I can't communicate with DSC using Ista and E-sys. HOWEVER it seems DSC is working fine because I don't see any "missing CAN messages" codes and I can turn on and off DSC. No error on dash. 

Recovered SVT from backup - didn't help
Reinitialised Flexray - didn't help
Checked Flexray ports using Tool32 and I have only PFAD 0 and PFAD 1 opened. When I open manually rest of it nothing changes. 

I had similar case with G30 but it lost communication with EPS - same scenario - no communication but EPS works fine. 

Anyone have an idea?

Try to write SVT Target manually in VCM with esys. after TAL calculation save it, and write it. often restores it back

yup, its just communication error. need svt write.

Solved!

Somehow E-SYS 23.10 couldn't write new SVT_SOLL in VCM. Used E-SYS 3.40 and it worked flawless.

Thank you guys!
