Maybe worth checking the replaced sensor connection is tight, correct, etc as not sure if the circuit is a series connection (meaning if one sensor is out the lot go out - like a christmas tree)
On the indicator stalk there is a bit you can twist/roll, this changes the display to the various different displays
Go into settings and select unit settings. Depending on the model of your car it's accessed by either pressing the set button or selecting settings on the screen
Maybe better to go for a reconditioned unit with a good warranty
The fluid in the existing box will tell a story of whether the clutch plates are worn out - smells of burnt toast and the filter should have trapped lots of debris. Which means the death knell for that gearbox.
Vauxhall gearboxes are renowned for being weak but still carry on until they finally go - which can be years, running with noisy gears, poor selection, etc
Check the large fuse / fuseable link for damage (e.g. cracks or burn marks)
Also, check the battery condition as this can drop to a low voltage when starting and this can flag fault codes
I've usually kept the vehicle weight on the ground and used an impact wrench on the nut and its worked.
As it is rubber mounted at the top of the damper then this can absorb some of the impact from the wrench and cancel out the torque being applied. Also may be worth using a long breaker bar if you can get it in the space
Can always spin it on a couple of turns to jack it up again
Maybe take it to a garage with a bigger impact wrench to see if it shifts
No, it would have to be a complete axle set at the same time for the handling not to be compromised
Powerflex are the best ones to purchase from experience but may cost more
I would put money on it being the turbocharger variable vanes sticking due to excessive carbon deposits
Try using a cleaner to remove the carbon - links below:

Could also be an adjustment required on the gearshift mechanism which has to be in Park to allow the key to turn back far enough to be removed
Try wiggling the gearshift to see if it makes it easier to remove the key
Sorry, misread your post....thought it said 'front locks'
Its possible but not sure....again if a scrapyard has the parts you can take measurements or offer it up....sometimes the manufacture won't change much metalwork to facelift a new version just superficial plastics...so certainly worth a punt and time in research
You could get one made by Samco or other companies offering silicon hoses
Any colour and also length, bends, etc

Also, check out Demon Tweeks as they do hoses

Yes that is correct and the earth pulses the injector
Cannot remember exact voltage but think (distant memory) that it is battery voltage (12 volts upwards)
