What are the reasons for poor air conditioning cooling performance in the BMW X4?
1 Answers
There are three main reasons for poor air conditioning cooling performance in the BMW X4: 1. Check the air conditioning filter. If the filter is too dirty and affects cooling performance, it needs to be cleaned or replaced. 2. Insufficient refrigerant in the air conditioning system pipelines due to low or inadequate refrigerant levels. This requires refilling the refrigerant while also checking for any leaks. 3. A dirty condenser can also cause poor cooling performance. You can directly rinse the condenser with a water hose. Alternatively, it can be removed and cleaned thoroughly, though this method requires taking out the condenser. Owners who prefer not to do it themselves can have it cleaned at a professional car wash.
