Having an air conditioner problem, especially in summer, can be a small but very constraining detail. In the city centre, you willingly open the windows of your Audi A3 to let in air, but the minute you get on fast roads, it quickly becomes complicated.
It can sometimes blow hot air while you asked it cold air, or it may well work intermittently.
You might not want to pay repair costs without finding out if you could do it by yourself to repair your Audi A3.
The goal of this article is to make it possible for you detect these possible problems in order to fix them as quickly as possible.
First, we will try to target the symptoms you identify on the air conditioning failure of your Audi A3.
Different symptoms on your Audi A3 air conditioner
You understand that it is no longer effective, for example:
It works initially to finally only give back moisture and run out very quickly, or it works but with a particularly long time to cool effectively. Or even simpler, it just does not cool down anymore.
First thing to think about at that time on your Audi A3, it is very likely that the gas charge is too limited. This may very well mean that there is a potential leak in the circuit. If this were the case, we really recommend you to request the advice of a specialist and not do this on your own, it carries great risks for your Audi A3 and more essentially your own health.
This factor is partly due to the wear and tear of time, but also to the level of quality of your air conditioning system. To put it plainly, if you have a top quality car, you are theoretically much less bothered with this type of problem.
Also make sure you keep the air conditioning in good condition all year round.
What does that mean? Simply use it every now and then for short moments during the year, which allows to avoid a “rust” of the system on your Audi A3. It uses up slightly more fuel, but as replacing your air conditioning system is much more expensive, you profit in the long run.
Different problems on your Audi A3 air conditioner
Now let’s look at some of the problems you may face on your Audi A3. Bear in mind that your air conditioner system is a very complicated system, made up of a multitude of parts that can potentially lead to failure.
First, as mentioned above, you may have a gas leak and consequently no pressure in the system.
Also, it is therefore likely that your compressor is out of order. Same observation as above, it is no longer possible to compress the gas, consequently no more pressure in the system.
Attached to this compressor of your Audi A3, a pulley allows it to rotate. If this one were to stop working, a chain reaction would occur with the compressor stopping, and therefore as mentioned above, no gas compression, no pressure…
We understand here that everything is connected and that each piece has a vital importance, just like a chain work, a single lacking link and the whole chain is stopped.
Another sensitive point, still on the theme of pressure, if by chance a too high pressure was felt in the circuit, a sensor will then be activated in order to stop the operation for safety. We can think about here the work of a protection fuse on the electrical circuit of your Audi A3.
About the temperature sensor, there may also be a failure. Just imagine that it is no longer able to determine the temperature of the inside of your Audi A3. As a result, it does not detect what to give the computer as information, which will lead to the air conditioning being turned off due to the lack of consistent data to be dealt with. Here again the air conditioning will have been turned off by the computer for safety reasons in order in order to avoid improbable situations, for example, where it is regarded as hot in your Audi A3 and sends cold when it is the opposite.
If you were to work with a professional, here is an idea of the prices you would have to pay:
Let’s imagine that you recharge your air conditioning with gas, it varies from 40 to 60€.
If, on the other hand, you had to replace your compressor, it would cost about 350€ new, much more affordable second-hand, around 150€.
So here is a set of complications you might face on your Audi A3, as you thought, in most cases it is better to call on an expert to avoid potentially major accidents. Remember that in the case of air conditioning, you work with compressed gas that is dangerous if you are not careful.
