Problem:

After read and write Renault Master SID321 ECU with Autotuner programmer,  adblue message pops up for 1 second then disappears, only happens on first ignition cycle after locking the van, did resets, EOBD clear too and battery off, have tried different solutions still the same problem, any ideas?

Solution:
Unplug the SCR module.

Reset the SCR module: before writing, disconnect the SCR module, write the file, and then reset all car —done!

If it’s after 2022, the SCR module is behind mud cover – need to be disconnected! Anyway make “start authorisation” from diagnostic and should be ok.

User feedback:
Disconnected SCR module at the end fixed, never had to before! But even with the 0 mileage the van still started and ran ok.
