Have you noticed any increase in the time the engine takes to start, especially from a hot start?

Welcome to the forum. That engine stalling sounds a lot like a clutch 'bite point' issue - have you noticed there to be a significant difference from the original clutch in the point where the engine revs starts to drop when you start to lift the clutch pedal? Have you tried 'slipping' the clutch a little more when moving off from standstill?

Welcome to the forum. Has the battery been fully load tested? This should be the first thing to do. A failing battery is definitely a prime suspect for ACC, Park Pilot and SS errors - as are failing ABS wheel sensors. U112300 is a generic code for communication errors between control modules. If the battery definitely tests as fully functional, faulty wiring, connectors or failing sensors can cause this DTC. Have there been any modifications made, I.e. changed steering wheel, etc?

Kia Ora Julian, welcome to the forum. Beautiful place to be.

Assuming the vehicle had this supposed 'aftermarket' camera fitted before it was sold to you, the seller is responsible for any warranty faults - they can't just refuse any responsibility because they claim 'aftermarket' unless it was specifically excluded. The UK Sale of Goods Act applies - even though the seller may say 'now out of time' the fact you reported the fault to them while still under warranty should take precedence.

Reported sound is inaudible.

How about trying a straight length of stiff wire, bent into a right-angle at the end, to hook under the piece and lift it enough to pull it out?

Very odd that the SS is still working, but strongly suggest a proper load test on the battery.

@Alasdair1 How did the MOT go, did the tester give an advisory on the rear wiper?

I'd suggest just topping-up the tank with premium diesel and possibly consider an early change of the fuel filter.

I presume you mean the glow plugs on the Merc?

Wow, nearly 20k a year!

Sump oil pickup or pump issues would also cause oil pressure problems and probable damage to engine bearings.

If the turbo bearings have been starved of lubricating oil, they will almost certainly be shot.

Best idea would be to get it properly diagnosed - if failing turbo is the cause (very likely) fitting a rebuilt unit would be my suggestion. What is the mileage on the Odo?

Beware, engine ingesting significant quantities of lubricating oil via a failing turbo can sometimes cause a diesel engine to run out of control.

Welcome to the forum. Turbo seals and bearings being 'toast' are most likely reason. Amber oil light should be telling you that engine oil level is low.

The problem with wiring is that copper will work-harden after a lot of flexing - this causes the conductor to lose flexibility and fracture inside the insulation. The answer is to use many more, thinner strands to make up the conductor.

What is the description of that part you showed?

To clarify - was the connector you removed for testing the one on the Shark Fin (GPS) or the one for the DAB antenna on the side window?

Not a great idea to consider skipping due services.

Your question about the TPMS depends on whether you have indirect or direct system. More likely you have indirect system - which uses data from the ABS wheel sensors and is not affected by changes in wheel sizes, provided all wheels are same size. Does your TPMS display actual tyre pressures - or simply flag pressure loss?

Very possibly affected by screen replacement if the rain sensor behind the RV mirror was damaged.

Wipers won't work on any setting if the hood is open.

Fixed that for you. 😁
