Hi ..... welcome to the Club It's a perfect car for local use more so than motorway but it should be mostly reliable and also economical Enjoy the forums

It does sounds like a loose or worn belt but equally I have found so many of the new belts nowadays are more silicon based than rubber based compound. They slip for a past time until they get warm. Try to stick to genuine manufacture belt (avoid anything made in china) Check also the tensioner is okay and if worn then replace this at the same time

there are some posts on google search relating to the PO409 code I would first start by running some cleaning solution through the fuel and give the engine a very long high revs run to burn off any excess carbon that has collected in the EGR or Intake Manifold

mostly timing chains are reliable if the correct servicing and maintenance is carried out when its specified and using quality oils and filters Please let us know how it goes !

possibly air mass meter is causing the jerking - try removing, cleaning and replacing Another possible cause could be the throttle pedal sensor needs replacing? Have you turned off the air conditioning as this will run a fan on start up

thanks for updating us and please let us know how it proceeds

Manufacturers were all found guilty of doctoring the figures by any means necessary - so they really are just guidelines. Your driving style, routes, terrain will all play a part in the overall fuel consumption....even air conditioning and having a roof box will play a part in the outcome

I would check the coolant pressure cap as my first point of call - replace if necessary as its quite cheap and take 30 seconds to do (only release the cap when the engine has cooled down)

I would advise changing the engine oil and filter as soon as possible. Having looked up your cars registration on Eurocarparts, it is listed as having a timing chain Try to locate a quality oil filter and get the best oil you can for the money - Castrol, etc

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

You could try using different protocol settings on the scanners (if available) to read the codes

You may be able to get the spheres re-gassed.....you could do on the Citroen and Hydrolastic spheres many years ago - look up Sphere repairs or regas

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
