Mercedes Air Conditioning Issues

A hot day in your vehicle without cool air. Or a frosty morning with misted car windows. Neither are ideal situations to find yourself in. So that’s why it’s so important to keep your air conditioning in top shape.

The air conditioning system will keep you cool during the summer, and ensure your windows demist efficiently during the winter. There will be more problems than just excessive heat if your vehicle’s air conditioner is faulty. It is possible that your visibility may be compromised, posing a risk to you and your passengers. Not only does an air conditioning system keep you comfortable, but it also keeps you safe on the road. 

We were recently contacted at Roade Main Garage by one of our clients experiencing air conditioning issues. Their Mercedes C Class was blowing hot air, even on the coolest setting.

The Issue

As soon as the Mercedes C Class arrived at our garage, we tested the air conditioning system and conducted a visual inspection. In this initial inspection, we were able to confirm the problem quickly.

The air conditioner blew hot air even on its coolest setting, but no warning messages appeared on the dashboard.

An air conditioning system that is too warm is most likely caused by insufficient refrigerant. Your air conditioning system needs refrigerant to produce cool air. Low refrigerant levels will cause the air conditioning system to fail.

However, there can also be other issues as the air conditioning system consists of many components that may malfunction. 

Several factors can cause your air conditioning system to fail, including leaks in the system, condenser or compressor failure, belt drive failure, or inactivity.

Therefore, at Roade Main Garage, our specialist technicians always thoroughly inspect your Mercedes’ air conditioning system when problems arise.

Our analysis includes the following steps:

• AC pressure test
• Leak test
• Code read
• Live data readings
• Consult the Mercedes dealer info
• And much more…

Our technicians conducted all of these tests to determine why our client’s air conditioning wasn’t working. We always perform a Mercedes air conditioning service thoroughly so that any problems are found on the first assessment. We didn’t want to assume it was a refrigerant problem, regas the C Class, and let our client drive away. The process may not have solved the problem long term, wasting money and time.

So our technicians checked the entire air conditioning system to rule out any underlying problems.

Problem Diagnosis

At Roade Main Garage, we employ a 15-step diagnostic process to ensure your vehicle’s problems are fixed the first time. Our in-depth analysis allows us to detect even the smallest issues that other garages might miss. If left unchecked, small issues can become major problems and fixing them comes at  cost. 

We needed to find the root cause of our client’s air conditioning system issues in order to resolve them. After closer inspection, our Mercedes technicians found that there was indeed a leak in the entire system. 

Repairing the Mercedes C Class Problem

Since our technicians have extensive experience servicing Mercedes air conditioning systems, they found the leak.

There was a fault with the condenser coil that caused the refrigerant leak. The condenser condenses refrigerant from a gas into a liquid. An inadequate amount of refrigerant may be supplied to the system if the condenser coil leaks.

Our technician replaced the faulty condenser coil with a high-quality Mercedes part after removing the faulty coil. UV dye was added to aid future leak detection, then our technician replaced the oil in the system.

At Roade Main Garage, we use genuine Mercedes or the equivalent high-quality parts to ensure your vehicle stays in prime condition. Using high-quality parts will help your vehicle perform better, last longer, and run more efficiently.

Following the repair of the Mercedes’ leak, the C Class was regassed, and the leftover gas was recycled. Our garage always disposes of leftover gas carefully to avoid having a negative impact on the environment.

Our team also decontaminated the Mercedes air conditioning system to remove any unpleasant odours and bacteria.

Once again, the Mercedes’ air conditioning system blew cool air! We were able to return the C Class back to the client on the same day, with a fully working air conditioning system!

Other garages may have regassed the C Class without addressing the underlying problem. As a result of our 15-step process and expertise, we were able to diagnose the leak and repair it correctly the first time. 

Our client even saved money, when compared to the cost of taking their car to the main Mercedes dealership in Northampton. You will always find better value at Roade Main Garage than at the main dealer, regardless of what service or repair you need for your vehicle.
