The technician will start the vehicle and turn on the air conditioning system, measuring the actual temperature at the vents at the lowest and highest settings with a thermometer; at the same time, they will connect a manifold pressure gauge to check if the refrigerant pressure in the high and low pressure lines is within the normal range, determining if there is a chronic refrigerant leak.

We cannot privately forge or re-stamp the original vehicle nameplate (this is illegal). If the nameplate is unclear, we will rely on the clear VIN on the windshield and the engine stamp as supplementary proof, and we will warn you of this risk before shipping.

Vehicles sold domestically in China only have the "Environmental Information List" and the "Vehicle Qualification Certificate," which are not the COC of the European system.
