Hi If you disconnected the battery and it is the same. 5 year old battery ... some battery doesn't last more than 2 years ... Battery voltage at rest ? Battery voltage when the engine is running ? If the wippers are still working, the CCU seams to be still working ... but a dying battery...

CTS ? Leak down test, all the injectors have the same return flow ? No fault code ? No fuel leak ?

Hi, Does all of your problems happed at the same time ? Or things start to fail one after another ? If you have the warning about an open door, the boot door lock have an issue ... I don't follow you at all, you say you don't have power to the front door, I asked if you had the front window...

Hi, If your EGR is leaking coolant, so blanking it will probably be useless. Better to replace it. For the Oil Cooler is better to know that is leaking before replacing it. Check your oil. Better to do a compression test first, to be sure that you have no Head Gasket issue. If you the Oil...

Low battery ?

Oil is used to lubricate the moving parts and also cool the engine. The oil goes throught very hot parts like the Turbo, If the oil is no more cooled, your engine will certainly overheat ...

In the car you certainly ear the pump relay. It not because you ear the pump that the pump is in the way out. Only if the pump is making too much noise. Should make less noise than a portable cooler.

Hi I don’t see any problem. The pump will run for almost a minute then stop if you don’t start the engine. The pump is near the rear the wheel arch not in the tank. Regards.

The gearbox has only one mount on the left side of the car under the battery. The gearbox is bolted to the engine and also bolted to the IRD. The IRD is cooled by the engine coolant. So you need to flush the coolant, remove the IRD, then the gearbox. Then you can remove the engine.
