Have any of the settings changed (e.g. bluetooth to your phone, etc)?
I would try pressing a few buttons to find mute, volume, etc
If it powers up then it won't be a fuse thats blown
Sounds like you have sorted it then - well done!
You have done all the checks in the correct way and come to the right conclusion
Only other thing maybe to recode the throttle body which was a thing on the slightly older Micra but may still apply
A good scan tool should have this function on it
Hi Stuart....welcome to the club
I would say just have the vehicle checked over at a garage and if it is in need of a service to then have this carried out before venturing abroad.
Also check your tyres for wear or damage and make sure all your lights are in working order.
You may need to get vehicle passes such as Vignettes but otherwise, convert your headlamps so that the beam is deflected to the other side (can get a kit from Halfords for that).
Good luck and enjoy your trip
Sorry that no one responded to your post.
One of the reasons on the old Micra 4 cylinder engine for poor idle was carbon build up in the throttle body.
When it is cleaned out and refitted, you would then have to perform a reset on it through a diagnostic scan tool which should sort it
I would suspect it is the brake pads moving backwards and forwards - usually happens if the pads fitting kit is missing and allows the pads to move in the carrier.
If it was the driveshaft joint then it would be constantly be clicking on acceleration and deceleration
Did you resolve the issue?
I was thinking it may be the Dual Mass Flywheel (if manual transmission) starting to break up
Usually noticeable when switching the engine on/off when it will start to rattle

i would say its a case for the ombudsmen and certainly run it past citizens advice to get some more guidance on pursuing a claim
If unsuccesful then a secondhand engine (with the revised cooling system parts) may be the most financially advisable way forwards
