Reduced A/C System Performance
On a 2015 Mazda MX-5, the air conditioning was not performing efficiently. The technician replaced the seal on the high-pressure line at the compressor connection, as it appeared to be the source of refrigerant leakage. After several months, the issue recurred. What could be the cause?
1. This is a known issue affecting MX-5 models manufactured between 14/05/15 and 19/06/18. The cause is damage to the high-pressure line. Engine movement creates a hairline crack in the high-pressure line that is difficult to detect visually.
2. Carefully inspect the high-pressure line where it connects to the compressor. If you find a crack, replace the high-pressure line and recharge the system with the correct amount of refrigerant. This should resolve the issue.
