Its never too late to 'break it in' by slowly and gradually increasing the revs over time to get it used to revving higher - easiest way I've found is drive it the same as normal but just use a lower gear for longer periods....just do it gradually and run on premium fuels

I would normally agree with you regarding the engine being run in but if a previous owner just took it to the shops once a week or crawled through traffic in urban areas the engine would not necessarily be run in correctly (many diesel engines with high mileage can be stripped down and still find the honing marks scored into the bores....suggesting that the engine has not been run in correctly). I have torn down engines with just 21k miles and found the bores to be completely worn but equally I have found engines with over 100k miles to still be as fresh as the day it was built. It all depends on how it has been driven. Another example is a BMW R1200GS motorbike I had for many years. When I bought it, it was consuming quite a lot of engine oil, I changed the grade but it didn't like it (just yet). The bike had only covered 24k miles but it was sluggish and didn't respond as it should. I rode the bike hard (as it should be ridden) with high revs in each gear and eventually it was a completely different bike. No longer did it consume oil but I could happily change the oil grade accordingly. The long and short of it is that it was not run in correctly and I managed to change that by riding it hard for a period of time. Most diesel engines are not revved hard enough to burn off carbon (which could be gumming up the rings into the piston and not sealing in the cylinder efficiently, blocked EGR, blocked DPF, etc. All they usually need is an 'Italian Tune-up' to keep it all clean. Moral of this lengthy reply is - if it is consuming oil between services then I would consider that my theory is correct. Also try a cylinder leak-down test which will show exactly which cylinder or valves have pressure leaking past them. Very easy test with visible and audible results

I can only really find springs which will drop the height but not sure about other suspension components to complement the springs (dampers, links, etc) https://www.lkperformance.co.uk/car-parts/suspension/lowering-springs/nissan/pathfinder

A couple of things come to mind - you could also try some additives to see if this improves things. If it is breathing heavy then usually bores/rings, etc but if you have tested compression (wet and dry) then this may not be an issue. Worth considering an additive such as StopSmoke or similar to see if any difference and also may change the engine oil for a heavier weight. Finally, if the car has been driven in a high gear and just cruised along for most of its life then it probably isn't run in yet....diesels (as you may know) need to be run hard to bed everything in and to maintain and low carbon emission level (gummed up rings, etc)

This is quite normal as it dims everything for nighttime driving. If you have the infotainment screen fitted then this also dims as well

Try this company https://www.petrolcaps.co.uk/

Sounds like they have arrived a diagnostic conclusion which seems quite reasonable. Not sure why it cuts out though, but sometimes this can occur when the engine revs 'stumble' Please let us know how it all goes

If it is coming from the interior (e.g. back of the steering wheel) then it could be the SRS rotary coupler as they can suffer from moisture and dirt ingress over time

I would use google lens and translate functions to define which controls do what

Hi....welcome to the Club Please let us know how you get on with it all Good to have you onboard

Hi .... welcome to the Club Nice collection of cars - good to have you onboard

Hi Simon...welcome to the Club You certainly have a good collection of Nissans Good to have you onboard

In the UK there is a windscreen company called Autoglass and they have all the equipment and necessary knowledge to set up the ADAS If there is somewhere similar in Sweden that you could take the car to for a check and if necessary get them to set it up correctly

I have used a company before that specialise in aftermarket audio replacement https://www.iceboxauto.com/nissan-murano-2015-18-gps-navi-android-auto-11-carplay-oem-style-radio-ni072 Not sure if the one listed is the same style as it states it for a later model?

First thing I would have suggested is fitting a new good quality battery. Also, not entirely sure if maybe the stored battery voltage needs resetting with a scan tool

`when did the fault start - following an accident or body damage?

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

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

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)

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

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
