	Checking
 Danger!	Risk of accident caused by vehicle starting off by itself when engine is running. Risk of injury caused by contusions and burns during starting procedure or when working near the engine as it is running	Secure vehicle to prevent it from moving by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.	AS00.00-Z-0005-01A
 Danger!	Risk of explosion caused by welding or soldering work on closed air conditioning system. Risk of poisoning caused by inhaling overheated refrigerant vapors. Risk of injury to skin and eyes caused by contact with liquid refrigerants.	Never perform welding work on or near a closed air conditioning system. No smoking or open flames. Wear safety glasses and protective gloves. Work only in well ventilated areas. Carry out repair work on the air conditioning system circuit only after the system has been emptied.	AS83.00-Z-0001-01A

		 Check whether all steps of the diagnosis trees from the adviser on "Vehicle air conditioning" technology have been processed.
1	Light up the complete engine compartment with a UV lamp, if necessary remove the remains of the existing contrast agent using special cleaner and wash the engine
2	Check the refrigerant circuit using leak detector additives	 Carry out steps as per the operating instructions of the UV leak detection kit.
		 Use only the approved MB leak detector additives. If it is proven that a different leak detector additive has been used, we will refuse to reimburse costs inside the warranty and goodwill term. Daimler AG reserves the right to perform reexaminations.

3	Inspect the air conditioning circuit for leaks	 If there is a pressure loss and no leak is found in the refrigeration circuit: 
		Remove expansion valve
