OBD Scanner result info:
P1434: Code reader got that one way off..... nothing to do with the A/C system!
P1434 means the Particle Filter Additive (PFA) system has excessive temperature or open circuit.
It is important because
As whilst this fault is active, the engine management system will deactivate the particle emission filter additive pump and also stop the cumulative calculation of the quantity of additive to be injected.
This means that is will stop the additive pump from injecting additive into the fuel tank.
This ultimately will prevent assisted regeneration and will lead to clogging of the particle filter - especially on shorter journeys where passive regeneration would normally take place (i.e. on a long journey where the exhaust can reach about 550°C.
The suspect here is the Additive Pump itself.
Fuel Additive Tank contains the pump inside. The unit is overheating, so is disabled.
