G70 Rear Right BMW Air Suspension Spring Shock Absorber Damper Original Type 37105A44646

G70 OEM 37105A44646 Shock Absorber Assembly BMW Gen7 Rear Right

The BMW G70 features the Magic Carpet Intelligent Air Suspension system, where front and rear air springs work in coordination with electronic damping. This system provides automatic leveling, height adjustability, and road-preview vibration filtering capabilities, balancing ultimate comfort with precise handling.

• Maintains consistent ground clearance (approximately 135-160mm, depending on mode) regardless of load, preventing rear sag from affecting headlight angle and handling balance
• Integrated stereoscopic camera scans the road ahead 30 times per second, allowing electromagnetic valves to adjust shock absorber stiffness at millisecond intervals before wheels encounter road imperfections
• Advanced damping system softens in advance to absorb impacts and increases damping during quick lane changes or braking to suppress body roll and pitch
• Includes high-pressure compressor, air tank, and four-channel distribution valve for independent control of each air spring
• Quick inflation and deflation response (height changes take only seconds) with compressor installed inside rear axle soundproof enclosure for quiet operation

This is usually caused by a leak in the air spring airbag or the piping. Rubber airbags, subjected to long-term temperature changes and road impacts, may develop microcracks, leading to slow air leaks. If multiple wheel positions collapse simultaneously, it is more likely a problem with the air supply system assembly (such as the distribution valve or main pipeline).

In most cases, the problem lies with the air compressor or its circuit. For example, a system leak can cause the compressor to work frequently and overheat, blow a fuse, or the desiccant inside the compressor can become saturated and fail. At this time, the vehicle will enter protection mode, limiting the maximum speed to prevent complete suspension failure.

This is most likely caused by the distribution valve sticking or a fault in the height sensor signal. If the valve core inside the distribution valve gets stuck, one of the air springs may not be able to deflate properly; if the height sensor linkage falls off or is dirty, it can cause the control unit to misjudge the position, making it unable to accurately adjust the height on one side.
