MODIFICATION NOTES
| 26.6.15 | Pressure drop in refrigerant circuit filled with nitrogen | BE83.30-P-1001-04A |
| Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. | Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | AS00.00-Z-0005-01A | |
| 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 refrigerant. | 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 drained. | AS83.00-Z-0001-01A | |

| 1 | Evacuate air conditioning system | AR83.30-P-1760LW | |
| 2 | Fill high and low-pressure sides of air conditioning system with nitrogen and check for leaktightness | ||
| 000 588 10 21 00 Leak tester | WS83.00-P-0008B | ||
Consistent ambient conditions must therefore be strictly ensured. |

| 3.1 | Extract nitrogen and fill air conditioning system | If a pressure drop was detected. | AR83.30-P-1760LW |
| 3.2 | Check refrigerant circuit for leaktightness using leak detection spray | In the event of pressure drop. In the event of leak in refrigerant circuit: ↓ Drain nitrogen, replace damaged components of refrigerant circuit and fill air conditioning system again. |
|
| AR83.30-P-1760LW | |||
| If a leak is not detected: ↓ Drain nitrogen. |
|||
| 4 | Check entire engine compartment using UV lamp | If traces of test fluid are found: ↓ Remove test fluid using suitable cleaner and wash the engine. |
|
| 5 | Fill refrigerant circuit | AR83.30-P-1760LW | |
| 6 | Add test fluid to refrigerant circuit | ||
| 7 | Search refrigerant circuit using UV lamp for leaks | If traces of test fluid are found: ↓ Replace damaged components in refrigerant circuit. If a test fluid is not detected: ↓ Replace evaporator. |
