Hello, have read car via OBD - MPPS13 - Bosch EDC16C2

tryed with Volta, write file back via OBD, reach 100% and sucesfull.
But car wont start, try to write back ori readed file and cannot, ecu wakeup error.

Also opened ECU and write with KTAG flash 1MB back the file readed with MPPS13 via OBD, car now works ok.

But i need now a DPFoff file with corrected checksum, I think there is a problem with checksum when I write the file, so I need a already checksum corrected DPFoff file.

Thanks for helping me.

Your file dpf off + checksum calculated in file.
Disconnect connector from temperature sensor and sensor differential pressure at dpf.
