Hi....welcome to the Club
Generally, most cleaners are suitable to help break down the carbon but you would also need to drive it hard to build up the pressure which helps to blow out the soot.
Worst case scenario would be to get the DPF professionally cleaned and refitted which will almost certainly resolve the issue
Let us know how you get on with it
Only other thing I can think of is the wiring loom that goes from the drivers door to the A post is broken.
Peel back the rubber gaiter and also inspect the connections.
Sometimes, when a door is opened and closed over time the wiring breaks where it articulates (also happens on tailgates).
I cannot think of any particular reason the windows are functioning as they are.
Maybe best to wait to see what occurs when you fit the new window switch.
Let us know the outcome
Hi....welcome to the Club
Usually, in the absence of a full size or space-saver spare wheel then there is a 'get you home' puncture repair kit.
This consists of a tin of spray foam which is introduced into the tyre via the valve and then the air compressor is connected to inflate the tyre to pressure.
Once you have managed to drive to a tyre repair centre then the tyre will usually need to be replaced.
Another option is to use 'Slime' in the tyres which prevents punctures and can be driven with it in the tyre permanently.
The usual way to release a bonnet is going through the grill area, either try releasing it with a screwdriver poked through but watch the radiator, etc
Alternatively, try removing the grill to access the latch mechanism
Hi....welcome to the Club
Wow! a Bluebird.....haven't seen one in a very long time.
Definitely worth doing up, would check the fuel lines and drain down any old fuel you can retrieve then look for any rodent damage and it should be as good as new.
Would love to see video of the old girl starting up for the first time after her long rest
Good to have you onboard and keep us updated on progress
Have a look at the reluctor (toothed) ring .....unless it has a Gen2 type wheel bearing type.
If the air gap is incorrect or toothed ring damaged/missing then no signal.
Also check the connections again to see if pins aligned or damaged
One other thing, worth checking resistance of sensors, maybe one is bad?
Not sure, but worth experimenting with switching the engine on and off using different methods to see if this invokes the fault.
Also, if the battery voltage dips too low by constant restarting then this could also be an issue.
Maybe worth turning the stop/start function off also to see if that resolves the issue
There is usually a good detailer in most towns around the UK.
Be aware that a detailer is different from a valeter and specialises in refreshing paintwork and vehicle finishing....expect to pay around £80 upwards for a paint refresh
A good detailer should be able to 'mop out' fine scratches and anything else can be smart repaired as opposed to a full repaint and a lot cheaper as well
Feel free to post up more photos if you wish.
I suppose the only shows I can think of are JapFest and the like which is more for modified cars.
If anyone knows of any shows and events for stock Japanese cars then post them here
