Product Name:Audi A6 C7 4G / A7 4G / A8 D4 4H Front Left Electronic Air Suspension Shock Absorber Assembly, Premium MLP Platform Front Adaptive Air Suspension Strut

Installation Position:Front Axle Left Side(Front Left Exclusive. Specially for premium Audi flagship models with factory air suspension. Perfect matched with front right OE 4G0616040N. Not compatible with mechanical non-air suspension version, new C8/D5 chassis.)

Product Description OE 4G0616039N is a front left electronic air strut exclusively for Audi premium MLP platform flagship vehicles. Widely fitted on Audi A6L C7, A7, A8 D4 with factory high-spec air suspension, also compatible with Bentley Mulsanne same platform air suspension version. The original factory has released multiple updated revisions. All suffix variants of 4G/4H series are fully interchangeable. Mounting dimension, air spring pressure rating, damping parameter, electronic connector signal and vehicle matching logic are 100% identical. It is one of the most widely sold replacement air suspension spare parts in the market.

This assembly comes with original adaptive electronic damping function, tuned for curb weight of full-size luxury sedan, high-speed stability and comfortable daily driving. It only fits vehicles originally equipped with front air suspension. Mechanical shock absorber and new generation chassis are not compatible.

Audi A6 C7, A7 and A8 D4 are luxury flagship sedans. Their factory air suspension delivers outstanding ride comfort and high-speed handling. After long-term city stop-and-go, highway cruising and bumpy road driving, common failures occur: rubber air spring aging, cracking and air leakage, which causes front left side sag, uneven vehicle height, overnight collapse and tilted body posture. Internal hydraulic oil degradation and seal failure lead to obvious residual vibration over speed bumps, loose chassis, insufficient support during lane change and poor high-speed stability. Degraded adaptive solenoid causes warning light on dashboard, failed damping adjustment, frequent activation of air compressor and overheating damage. Continuous driving with faulty strut will cause secondary damage to air valve block, height sensor and air compressor, resulting in expensive whole air suspension system repair cost.

Our 4G0616039N front left electronic air strut is 1:1 moulded strictly according to original OE specification. Tuned for Audi luxury comfort chassis. Adopts multi-layer imported high temperature resistant explosion-proof air spring, anti-rust piston rod, multi-stage high pressure sealing structure, long-life hydraulic oil and high precision electronic component. Every unit is 100% tested for air tightness, high & low temperature endurance, fatigue impact and electronic signal calibration. It permanently fixes common issues: air leakage, front end sag, tilted body, loose chassis, abnormal noise, electronic fault code and disabled adaptive damping. It is a complete pre-assembled unit, plug & bolt installation without chassis modification or rewiring. After installation, simple air leak check, vehicle height calibration and adaptive matching will restore original premium ride quality, level body posture and all intelligent air suspension functions. Low return rate, ideal for luxury car repair, local auto parts stocking and cross-border export.

5. FAQ

1. Q1: Can OE numbers with different suffix replace each other? A: Yes. 4G0616039N/T, 4H0616039AD/AF/AH are factory upgraded interchangeable parts. Hardware, electronic function and installation effect are 100% identical, freely interchangeable.
2. Q2: Are A6C7, A8D4 and Bentley Mulsanne using the same strut? A: Yes. These vehicles share the same front air suspension assembly. Mounting hole, damping and electronic system are fully compatible, direct bolt-on replacement.
3. Q3: Does it fit new A6 C8 or A8 D5? A: No. New chassis air suspension structure, connector and control program are fully upgraded, not compatible with old 4G/4H chassis.
4. Q4: Can I install it on low spec vehicles without air suspension? A: Not available. Non-air suspension version has no air pipe, compressor or control module, hardware cannot support air strut retrofit.
5. Q5: Does coding or programming required after replacement? A: No programming needed. Only air leak inspection, vehicle height calibration, adaptive matching and fault code clearing are required.
6. Q6: What symptoms mean I need to replace this front left strut? A: Front left side low, front sag after parking overnight, uneven body height, heavy vibration over bumps, loose chassis, poor high-speed stability, air suspension warning light, frequent compressor activation, obvious comfort drop.
7. Q7: Only left side broken, can I just replace single strut? A: Not recommended. Air struts on luxury cars age at similar speed. Single replacement will cause inconsistent damping and support, leading to pulling, tilted body and uneven tire wear. Replace in pair with 4G0616040N is strongly recommended.
8. Q8: Will mixing 4G and 4H chassis parts trigger fault code? A: No. Original 4G/4H revised parts are officially interchangeable, electronic signal matches perfectly, no error code or function failure after installation.
