In this video, we can see the problem of a 2017 Volkswagen Tiguan with a tailgate that won't open. The problem arose due to rear damage, which also caused a broken rear light and water ingress in the rear compartment.

The tailgate button has oxidised (the contacts have turned green due to oxidation) and no longer sends the opening signal. The first solution is to replace the lock, which also includes the rear camera: this is an expensive replacement, costing between £150 and £300. Another solution is to check the wiring, inspecting the connectors and cables under the tailgate for water damage.

Obviously, the definitive solution is to replace the light, but a temporary solution is to seal it with waterproof tape, such as butyl tape. If the tailgate is stuck, you can open it from the inside (there is a lever inside the boot).

Glow plugs, as the name suggests, raise the temperature of the engine in diesel vehicles to allow for easier starting. The manufacturer, in this case, Fiat for the Ducato 2.3 Multijet, specifies how often they should be replaced, and a warning light will illuminate when it's time. This work is carried out under the bonnet. First, remove the upper engine cover, then lift the coil and, using a socket wrench of the appropriate size, unscrew the glow plug to remove it from the base, followed by installing the new one.
