Discover a air conditioning problem, especially in summer, turns out to be a very unpleasant little detail. In the city center, you can easily open the windows of your Audi Q7 to air out a little, but when you reach main roads, it quickly becomes very restrictive.
The idea of this article is to help you identify these possible problems in order to remedy them as quickly as possible.
Before going into details, we will try to list the potential symptoms that you recognize on the air conditioning failure of your Audi Q7.
Different symptoms of air conditioning failures on your Audi Q7
You realize that it is no longer working very well, for example:
It works in a first step to in the end not just return humidity and run out very quickly, or it works but with a particularly long time to cool effectively. Or even simpler, it simply does not refresh itself any more.
The first thing to think about at this time on your Audi Q7, it is likely that the gas charge is too low. Which can reveal that there is probably a circuit leak. If this is the case, we strongly recommend that you seek the advice of a specialist and do not do this alone, it carries great risks for your Audi Q7 and more important for your own health.
This factor is partly explained by the wear and tear of time, but also of the quality of your air conditioning system. Basically, if you have a newer Audi Q7 you are theoretically much less hassle with this type of malfunction.
Also ask yourself the question if you keep the air conditioning in your Audi Q7 in good condition all year round.
I mean by that, just to use it from time to time short periods of time all year round, which has the effect of preventing "rust" of the system on your Audi Q7. It uses a little more fuel, but since replacing your A / C system is definitely more expensive, you naturally benefit in the long run.
Different air conditioning problems on your Audi Q7
Let’s now see different malfunctions that you could be faced with on your Audi Q7. You should know that your air conditioning circuit is a very complex whole, made up of a multitude of parts that can potentially cause a breakdown.
First of all, as mentioned above, it is possible that you have a gas leak and so that you do not have any more pressure in the circuit of your Audi Q7.
At the same level, it is also possible that your compressor is out of service. Same observation as above, so it is impossible to compress the gas, thus more pressure in the circuit.
Attached to this compressor of your Audi Q7, a pulley allows it to run. If this were to work, there is a chain reaction with the compressor stopping, and therefore as mentioned above, more gas compression, more pressure ...
We realize here that everything is linked and that each part has an essential importance, such as chain work, only one missing link and the whole chain is stopped.
Another sensitive point, still on the theme of pressure, if by chance, conversely, too much pressure is felt in the circuit, a sensor will then play its role in order to stop the operation for safety. We can compare here the work of a fuse protection on the electrical circuit of your Audi Q7.
On the side of the temperature sensor, there may also be a fault. Just imagine that the sensor no longer has the ability to determine the temperature inside your Audi Q7. Logically, it does not know what to give as information to the computer, which will cause the air conditioning to stop because the data would no longer make sense. Here again the air conditioning will have been cut for safety by the machine in order to avoid delicate situations, for example where it considers that it is hot in your Audi Q7 and sends cold while it is the reverse.
If you were using a professional, here is an idea of the prices you should pay:
If you bought a gas cylinder, it would cost you 40 to 60 €.
If on the other hand you had to change your compressor instead, this represents around 350 € new, Nevertheless much cheaper used, around 150 €.
So here is a set of problems that you might be facing on your Audi Q7, as you guessed it, in the vast majority of cases it is best to seek professional help in order to avoid possibly serious accidents. You should know that in the case of air conditioning, you are handling compressed gas which represents a danger if you are not foresight.
