UPDATE: Secondary system errors were caused by human error and unfortunate circumstances.

The workshop has since resoved all and the car is as good as new. One extra star for the courteous service at reception and exhaustive explanations. These days cars are computers on wheels and are pretty complex creatures. Mechanics often have to take the role of doctors. What a hadache. Where did the 90s cars go? Anyways - good ending to the story with positive outcome.

Thank you!

Issue in Duster with Adblue sensor and injector calculators. Mechanic reprogrammed the calculators which fixed the adblue orange light in the dashboard. This reprogramming, however, produced another error related to the ESP. When I start the car now, the wheel steers slightly to the right by itself. After a few meters of driving it resolves the direction of the wheel but the ESP orange light and the orange Wrench light remain lit on the dashboard.

The mechanic explained this may be caused by the fact that the reprogramming of the adblue sensor calculator feeds the car's ESP system with information which it considers erroneous but said it's safe. I do not understand yet how the AdBlue system is linked to the ESP system.

I understand that there is a software update that Dacia issued a year or two ago. I do not know why reprogramming was needed instead of directly applying the Dacia update to the AdBlue system.

I booked another RDV to fix the newly-produced ESP issue with more time needed by the mechanic to test and fix. Ultimately, I'd rather have the AdBlue system confused than have the ESP system confused.

For me this is job half done. Therefore I give two stars. I will update to four once I get the car back without any errors.
