The sharing of some vehicle repair and maintenance cases is updated irregularly. Let more people understand some tips in daily car use, maintenance, and testing. Use cars to understand cars better!

The car owner said that after BMW’s air conditioner was turned on, the compressor would always make waves of harsh sounds that sounded like a beginner playing an erhu. I couldn’t stand it, so I had the idea of replacing the compressor. What’s wrong is that the car is already insured. I went to the 4S shop and asked about the price of compressor parts being more than 6000 yuan, plus the working hours would cost 8,000 yuan. I had to pay for this money myself.
After withdrawing from 4S, I found a friend to get an original air conditioner compressor. The price dropped a lot. Are there any sensitive topics that involve some car owners ‘personal privacy issues, so the specific price will not be disclosed here.

The only purpose of these two cars arriving at the store was to remove the old compressor and replace it with a new compressor to solve the abnormal noise.

BMW Original Air Conditioning Compressor

There are some differences on the label, QR code and barcode

The three bottles of Sinochem Blue Sky-Golden Refrigerant (Snow Seed-Refrigerant) that came along with the compressor continue to circulate in the air-conditioning refrigeration system and play a cooling role through its own state changes.

Advantages: No corrosiveness, no environmental pollution, purity R-134A reaches more than 99.9%, good cooling effect

The new compressor is installed in place and refrigerant is added to complete the replacement.
Finally: the compressor can be repaired, such as abnormal noise caused by damage to the compressor’s electromagnetic clutch or severe internal wear of the compressor. However, the owner went through a friend’s channel and got the goods, so he did not consider maintenance in the end, but carried out the operation of replacing them with a new one.
