only other way around it is to find another dealer that may not be local but can get you seen quicker

V7 is the last ever maps card been released for the qashqai, the maps on it are from 1st half of 2021.

i would clear all the codes and check again in a wk or so and see if any re-appear, as you don`t know how old all them codes are

so if new batt is not getting the car started still then yes starter motor next, any good garage should be able to check that for you, did you fit the correct batt for your car

I always use a small independant local garage. To get your batt checked use kwick fit. Halfords etc. Once you know if the car batt is no good order it online and fit yourself £110

Tryca good brand of 2032 batt for the keyfob. They should last around a yr

Take a few mins normally with engine running

Any good garage should be able to test the condition without telling you that you need to replace this and that

Looks like the led screen is on the way out. Think you would have to replace the whole unit.
