MAZDA CX7 ADBLUE COUNTDOWN

[zita]

Hi everyone.
I have a mazda cx7 diesel 2.2. There was a warning in dashboard that the adblue is empty but actually it was full. I changed the adblue tank in the official mazda workshop but still the message and the countdown is there.. only 500 km left (safe mode) and if it goes to 0 it wont start.. they can't reset the countdown. The mechanic says he needs to flash an original file in the ecu (as i understand, i m not an expert), otherwise he has to unblock eeprom.. is that right?
The car is in the workshop for 1 month now and nothing happens.
I need some help please.. Thanx in advance..

You can remove adblue on software, easy ECU Denso RF7K/RF8K!

If you have tool post dump and we can help, or use garage tools to fix (Snapon-Delphi-Launch) etc

So you need reset adblue with same soft from mazda or equivalent.
