FAQ
Q: Do I need to replace the relay when installing this pump?
A: Yes, absolutely. To maintain your warranty and ensure the longevity of your new compressor, the relay must be replaced. Good news — this kit already includes a new high-quality relay, so you have everything you need for a complete and reliable installation.
Q: My BMW 5 Series G31 / G38 keeps dropping overnight — is the compressor definitely the problem?
A: Not necessarily. Overnight suspension drop is often caused by air leaks in the air springs, air lines, or valve block — not the compressor itself. We strongly recommend checking the entire system for leaks before replacing the compressor. Installing a new pump into a leaking system will cause immediate damage and void the warranty.
Note: Before installing the new compressor, please ensure the air suspension system is checked for any leaks (such as in air springs or lines), as leaks cause the compressor to overwork and lead to premature failure.
