When it comes to cooling, comfort, and heating, many cars don’t come close to Volkswagen because almost all its vehicles are equipped with the latest mobile A/C techs.
It will surprise you that almost all their vehicles developed since 1990 come with top-notched variable A/C compressors for maintaining constant cabin temperature, giving the buyer driving comfort.
Volkswagen is a car to reckon with when looking at its qualities and amenities, but just like other cars, Volkswagen may develop some faults which you may or may not be familiar with, and one such fault is the Volkswagen A.C.

Volkswagen A.C. Repair
Below are the Volkswagen A.C Repair steps…
1. Checking the Gas Charge
The pumped refrigerant gas around your A/C circuit absorbs the heat from your cabin. It is then released at the condenser in front of your radiation. If the refrigerant/gas is not maintained at the average level, It can destroy the seal due to overheating the A.C. system.
You can check your gas charge with a specially designed recovery machine and refrigerant gases to weigh your gas system. The purpose of checking is to give you an accurate measurement of your gas and a more precise picture if you lost any of its refrigerants.
The system of the A.C. is wholly sealed, and its usage of gas differs from its usage of fuel. It uses gas by pumping the gas around the system and, by so doing, sending the heat from your cabin away into the outside air.
If your car fails to perform well because it has a low gas charge, you should be able to identify where the problem is coming from.
2. Finding the Leak
Once you have identified the low gas charge to be the cause of your underperforming A.C., you will have to find the leakage. The task would be much easier if your system had a dye additive that could show under U.V. light. All lines and components would be checked with the U.V. torch until the dye stain was found.
Some cars don’t have the U.V. dye. If your vehicle doesn’t include a carrier, then road damage or oil stain would be examined.
Testing Electrical Sensors and Drive Units
In some instances, nothing is wrong with your V.W.’s gas charge, and vehicle components are excellent. At this point, you have to look at your electrical sensors and control units that drive the A.C. pump. The best thing to do here is to use a scan tool to access the A/C control unit. When access to the A/C control unit is granted, you must download the live data to know where the electrical fault is coming from.
If you have a problem getting some of the tools you need to repair your Volkswagen A.C., it is best to visit a professional mechanic for a fix.
