Unfortunately town driving will always give very low MPG However, on extra urban road journeys (e.g. 40 - 50 mph constant) should deliver best MPG Maybe look at alternative routes which include more constant speeds rather than just town and motorway.....maybe longer route but pays back with better MPG

I would clean out the throttle body and also check for split or perished rubber hoses in around the inlet area

Sounds like the throttle housing needs cleaning out also check for split or perished rubber hoses in and around the inlet area

You should be able to get a secondhand one and recode it to the engine (also look out for a Renault equivalent as same engines)

Hi Ross....welcome to the Club Wow! 350Z is a superb car to have in your garage, cannot even remember the last time I saw on the road. Keep us updated on the work you're carrying out

Hi Sam Welcome to the Club and welcome back to the wonderful world of Nissan !

Hi....welcome to the Club Micra's are pretty good all round and you shouldn't have too many issues with them if maintained correctly Good to have you onboard!

There is a coding procedure for the throttle body that can be carried out with a scan tool. Also, check for any air leaks on the induction side (intake manifold, etc) rubber hoses split, etc

I believe it is on the bulkhead or inner wing area or if not it may be built into the tank itself

I would have the battery condition checked. Although it may start every time, the condition may be slight off par and this could affect the stop/start system and also it may need the charging system voltage to be reset (if required) as this can flag the light

Does the engine performance suffer when the light comes on? I would definitely take the car to another garage to have it checked as it should be a straightforward diagnosis and repair and definitely not a serious issue that would cost £4.5k to resolve

Not sure what could be if it sounds electronic If not then it could be a vacuum leak from the engine/brake servo which could sound like a beep sound?

Only other thing I can think of is an engine flush and the oil refreshing once more. A garage should be able to take readings of the oil pressure to determine if it is up to scratch, if not then flush the engine.

SOunds like poor connections due to corrosion. Chances are the battery terminals or starter terminals are corroded ....check these and go from there. Don't forget to check all the earth leads and connections as well

I would imagine the sensor should be centrally mounted so under the center console is more than likely location

I would definitely get an oil and filter change as soon as possible to start with

Hi....welcome to the Club Generally, the Qashqui is reliable but the older ones were more prone to recurring faults. However, it is like any other car, as long as the servicing is kept up to date then this will limit the unreliability issues (hopefully)

Thanks for the heads up, not sure if this will become an issue for many makes of car in the future. Nice to know the solution though, thanks for passing it onto the forum

Hi....welcome to the Club Let's hope you won't need the advice from members and continue to have trouble free motoring. Good to have you onboard!

I believe it is air in the system which you can clear by turning the wheel from lock to lock

Usually when you remove the circlip (work it off by using a small flat blade screwdriver) and usually the shaft will come off with a soft faced hammer (copperhide or plastic)

Here is a handy site to see which oil you need https://www.castrol.com/en_gb/united-kingdom/home/car-engine-oil-and-fluids/motor-oil-and-fluids-finder.html?customerType=retail

If it were me I would go with the steel rims as more durable off road

Yes, you can....somewhere like Milner Brothers would have them but also remember to raise the rear as well to match the ride height
