Hi....welcome to the Club I would say this may have been a last minute substitution due to the semi-conductor shortages. A lot of manufacturers have gone this way as a result of this issue and have released vehicles with lower level technology fitted

None that I can think of except for using a SatNav with speed readout

It would be advisable to change the fuses in case there is a slight fracture that cannot be easily seen After that then you will need to check the circuits with a multimeter to determine where the fault is

Try checking the tyres (front and rear) for deformation Usually chinese tyres are renowned for this If you jack up the car on each corner in turn and rotate the wheel to see if it spins true and does not deflect at all

Some cars use an audible brake pad wear indicator that scrapes against the disc when it reaches a certain wear limit When you hear that you will need to change them immediately

You could try a remap to see if this improves the situation. Relatively cheap and would improve the engine performance, drivability and economy

Any developments with the car?

An aftermarket audio unit would be the best bet https://www.iceboxauto.com/iba-nissan-entertainment-systems#/specFilters=2!#-!225

Could be the battery in the key fob or the buttons have broken internally which does frequently happen

Hi Chris.....welcome to the Club! Good to have you onboard

I would go back into the fusebox and look for any missing or blown fuses Chances are it has to be related to your accessing the fusebox previously

look forward to hearing how you get on with it 🙂

Hi Adam.....welcome to the Club I would think that summer tyres are fine for the UK unless you live in remote areas with heavy rainfall. All season tyres are okay to use but will wear out quicker and cost a lot more usually

Hi Trevor......welcome to the Club You could take a feed from the ignition feed to the new stereo head unit. Alternatively, Halfords sell aftermarket radio adapter leads to plug straight in and this would not affect any other parts such as the clock

Hi Luke.....welcome to the Club I would say you are correct that it is the antenna and as far as I am aware it would not need coding to the vehicle as it does not generate or hold the immobilise code (the ECU would have that information) it simply amplifies the signal from the immobiliser chip in the key fob

Hi Stephen.....welcome to the Club It could be a central electrical fault, anything from a battery connection to the fusebox and associated fuses. Careful examination of all connections and wiring leading from the battery to the fusebox may unearth the fault.

It sounds more like a crankshaft position sensor issue as these tend to fail when the engine is hot.

Hi....welcome to the Club It seems there is an M9R802 engine which is a 2.0DCi engine fitted to some of the Renault range but also would have found their way into the Nissan range that had this engine size Here is a link to some more information on the engine: https://www.proxyparts.com/car-parts-stock/result/engine-code/m9r802/part/engine/

It sounds like it could have been misfuelled but would definitely take to another garage to diagnose it further. Even with a misfuel it could clear and run well if the fuel filter is changed and topped up with correct fuel. Also, you mention it needs a bump start then maybe the battery needs replacing which could also lead to the symptoms you describe. I would definitely get the car taken back to your house or another garage

Hi....welcome to the Club Fantastic condition and can't be that many left on the roads now. I have used is AutoDoc for hydraulic boot struts https://www.autodoc.co.uk/spares Good to have you onboard!

I would check all of the earth leads coming from the battery negative terminal and those leading from the engine and gearbox to the chassis on the underside of the car and in the engine bay....not uncommon to break and lead to this type of fault

If you are referring to the open pipe coming from the side of the engine then this is more than likely the air conditioning discharge pipe which takes the moisture from inside the car (when on recirculate) and dumps the water into the floor. Check the fluid being emitted from it is actually water and not diesel....if it is diesel then it would need to be booked in for immediate repairs without being driven as this creates a hazard for all road users.

Hi Sparky....welcome to the Club What an absolutely superb 350Z Always a pleasure to see such a fine car! Good to have you onboard

In my opinion I would acquire a new plug as you are dealing with high current and particularly when wired to your house if any issue were to occur in the mains supply then the repercussions could be huge.

I believe they will do but worth checking one on the car for clearances, etc
