Why can't the rear shock absorber of the BMW 730 be raised?
2 Answers
BMW 730 rear shock absorber cannot be raised due to abnormal control system. Here are the details about the BMW 730: 1. Function: The vehicle shock absorber ensures smooth driving by buffering vibrations. Without shock absorbers in the suspension system, the vehicle would experience unstable driving. 2. Model information: The BMW 730 is a high-end luxury car produced by German automaker BMW. Belonging to the BMW 7 Series, it is exclusively manufactured in Germany and replaced the previous BMW 6 Series in 1977. The BMW 730 is BMW's first large luxury four-door sedan, equipped with an inline six-cylinder engine.
I've been driving a BMW 730 for several years, and last time the rear shock absorber just wouldn't rise no matter what—what a headache. I thought it was a settings issue and tried restarting the system, but it didn't help. Later, when I took it in for repairs, it turned out there was a leak in the air suspension piping. The technician said aging is common, especially after prolonged use when rubber components crack, causing air leaks and loss of height control. Replacing the part isn't cheap, costing at least a few thousand yuan. And if you delay repairs, the car's bouncing will accelerate wear and tear, potentially damaging the rims. I recommend regular checks on the suspension system—like having a professional shop perform a pressure test every six months—so leaks can be fixed early. A little maintenance like this can save you big money and keep your ride safer and more stable. Don’t end up like me, driving over a bump at night and nearly causing an accident because I didn’t address the issue in time—regret it later.
