Not entirely sure but I have only ever encountered a few methods of retaining the gear knob. Grub screw (usually small and hidden underneath the knob, screwed thread (twist off), detent clip (needs pulling up with force) - beyond that I'm not sure. I would start with trying to locate the grub screw, if not then gently try twisting anticlockwise, then if no joy then try knocking it upwards (I tend to hold onto the gear knob and with your other hand wallop your gripping hand to force it up. Beware to keep you face out of the way :-)

I think you have the correct diagnostic procedure for ascertaining the fault(s) but maybe take a step back and diagnose each code, warning lamp and issue individually. Reason being there could be one overriding fault that is causing it or there could be a couple of faults present.

If you would like to wrapped them with gaffer tape to give more support to the hoses and then evaluate if there is an improvement in the performance then you can decide it the hoses need replacement

Yes its quite normal for the hoses to expand when pressurised from the turbo boost however, if they feel very soft and squidgy when you squeeze them they are probably in need of replacement as the rubber would be perished with age

They get to a stage when they are worn out and worth replacing with an aftermarket system. Take a look in Halfords to see what aftermarket audio systems they have which should fit your existing radio slot

If it is 'clacking' as you turn to a sharp left or right turn then it does suggest that the joint is worn. What else makes you think you have a problem with the joint?

I would suggest to pop into Halfords and look at their range of aftermarket audio systems. I recently bought a new Sony double din that has reverse cameras, satnav, and loads more functions than I would probable never use. They also adapter kits so you can wire in your steering wheel controls as well as fascia plates to make it fit the dash

If it is screaming high pitch noise then it is more than likely got a small leak somewhere but in general you will hear a nice constant low whistling tone while the turbo spools up

Sounds like turbo boost isn't there - are there any strange sounds like whistling or a deeper sound (sounds like a burp) as this can signify that either the turbo or intercooler is leaking and creates a whistling sound and if its deeper then one of the rubber turbo hoses is split. I would demonstrate both sounds but luckily I can't record sound on here 😁

I would be very tempted to take it back to the dealership and ask them to explain it to you - not only is it from the Nissan dealership so they should be well informed of any procedures and also the liability if there is any issues with the system. Please let us know how you get on with it

Hi, I would say Halfords but probably not on your model, I guess any decent independent mechanic should be able to change it. Not only is it the one lamp at the moment but they usually follow in pairs. I can recommend a mobile mechanic, Sam Mee who is top-drawer and would be able to do that job (assuming it doesn't need to be from underneath on a vehicle lift to access the bulb). Let me know if you want his number and I can PM it to you. Being based in Bournemouth myself I know many garages and some/most I would not advise going to but there are also a lot of very good garages and mechanics out there who are respectful of customers and their cars. (I know because I taught many of them over the years). Give me some garage names (best PM them to me) and can advise on their reputation as best I can. Cheers, Trevor

I would recommend taking the car to an car audio specialist I believe there are still some left in most towns. They may be able to guide you to a reset or firmware update - alternatively they may offer to sell you a new multimedia replacement which would be so much better than the original one

how low was the warning down to? maybe less than a certain amount (e.g. zero or very low timeframe) and it won't reset unless through a scanner.

Not sure to be honest but found this AI summary which could shine some light on your issue TSR Audible Warning Details: Speed Limit Change: A single chime sounds when the system detects a new speed limit sign. Overspeed Warning: If the vehicle exceeds the detected speed limit, the display flashes and a chime sounds four times. Customization: Within the [Driver Assistance] > [Traffic Sign Assist] menu, drivers can set the system to: [Warning]: Both visual speed limit display and audible overspeed chimes are active. [Info only]: Only the visual display is active; audible alerts for speed changes are disabled. Temporary Suspension: The chime can be temporarily muted by slowing down or using the steering wheel scroll dial.

I would be tempted to drive it more to allow the battery to charge and to activate the brakes on loose surface to invoke the ABS. Erase the fault code memory and rescan it to see if the fault returns

Hi @Johnj good to see you back 🙂

Thank you so much for responding with the solution - I'm sure many members will benefit from your time in diagnosing and cost (albeit a cheap component) rather than replacing everything in a process of elimination.

Can't say that I have noticed exhaust pipes being this colour except for when engine oil has been sprayed over the exhaust and stained it

The oil level sensor should be on the sump and as long as you have topped it up on a level surface then it should give a true reading - it may be worth checking the connection to the sensor and ensure not contaminated with water, corrosion, mud, etc

Not sure as the car is quite new so unless something has damaged the reservoir bottle or a hose has come detached ?

Great diagnosis and sometimes you can narrow it down to one part (hopefully a cheapish part) and then throw caution to the wind - it then either works or it doesn't.

Thats a great outcome - and warranties are handy for that reason

I would read reviews of different independent garages on Trustpilot and then narrow down to one you think you can trust (not always the cheapest one)

Is the engine petrol or diesel ? Turbocharged?

I guess it depends what the load is in the back - loose rubble or large (but lightweight) objects. Ultimately, the brakes will adjust on the rear to how much load is being carried but the tyres will only ever be suitable to certain speeds and loads. I always work on the principle of driving the appropriate speed for the roads and conditions.
