我有一台帕萨特 B5 GSi,它已经陪我走了快5个年头了,一直以来都让我非常满意。老帕的空调制冷随着年纪的增长已经慢慢不行了,虽然定期去加制冷剂,总感觉没有开始的时候那么好了。前些日子,天气比较炎热,我照例打开空调,却发现老帕的制冷情况比以前更差了,把手放在空调出风口附近,感觉吹出来的风时冷时热,温度非常不稳定。而且在市区里遭遇堵车的时候状况就更明显,赶紧找了个比较空的路边把车停下来看看,感觉从出风口出来的冷气温度又恢复正常了。我还是不不太放心,轻轻踩了一下油门把转速提起来,感觉冷气的温度又开始不稳定了。难道是我没有把制冷剂加够?应该不会,不久前我才去加了制冷剂,而且我常去的那个维修厂是老熟人了,他们应该不会忽悠我。没有办法,夏天已经来了,为了不让自己在酷暑中受煎熬,我只好把老帕开到了维修厂,让他们帮我看看到底是怎么回事。在看过老帕的病情后,维修师傅也没有太大的把握,他决定还是按正常的修理程序来对老帕做一个体检。首先是对空调的系统压力做了一个检测。启动发动机,打开空

And when the traffic jam in the urban areas when the situation is even more obvious, quickly find a relatively empty roadside to stop the car and take a look, feel out of the outlet air temperature back to normal. I still do not rest assured, gently stepped on the accelerator to lift the speed, feel the air temperature began to instability. Could it be that I did not add enough refrigerant? Should not, not long ago I went to add refrigerant, and I often go to the maintenance plant is an acquaintance, and they should not flicker me. No way, summer has come, in order not to allow myself to suffer in the heat, I had to open the maintenance of the old factory, let them help me to see what is going on in the end. Having seen the condition of Papa, the maintenance of the master is not too sure, he decided or according to the normal repair procedures to do a physical examination of the Papa. The first is to do a test on the air conditioning system pressure. Start the engine and turn it on
