[Diagnostic Case] Maintenance Laolang’s cooling power drops
IvyHenry 
11 Lao Lang had unknowingly been 85,000 kilometers. During several driving times last week, I discovered that the AC light had been on normally, but the outlet maintained natural wind. So when I returned home, I opened the cover and inspected. When the AC light was on, the electromagnetic clutch made the compressor run normally. The air conditioning piping was cold and contained condensed water. However, through the actual data measured by the Yuanzheng computer, the actual temperature of the evaporation box was high, and the outlet was difficult to reach below 10 degrees, and the cooling pressure was low.
Based on the above situation and analyzing the cause of the relevant failure, I judged that the refrigerant was missing, but the refrigerant in the vehicle air conditioner would not be missing for no reason. It must be a leak that caused the missing. A similar situation occurred two years ago. I replenished two bottles of electric refrigerant after vacuum, and the refrigeration immediately returned to normal after the addition.
Because I did not have a pressure gauge or pressure equipment, I had to go to Siaisi store for subsequent troubleshooting, so I set off for a Shanghai Volkswagen Siaisi store![]()
