A1673200302L Rear Left Air Suspension Shock with ADS for Mercedes Benz E-class w167 GLE450 GLE450 GLE580 2019-2022

1. Product Introduction

Original OE Number: A1673200302L

Product Name: Mercedes-Benz W167 Rear Left Air Shock Absorber, GLE/GLS Rear Left Air Suspension Strut Assembly, Rear Left Air Strut with ADS Electronic Adaptive Damping

Installation Position: Rear axle, dedicated for left side. Fits Mercedes-Benz W167 chassis GLE and GLS vehicles equipped with factory Airmatic air suspension and ADS adaptive damping system. It is a high-frequency vulnerable service component for load bearing, intelligent ride height adjustment, shock absorption and body posture balance on the left rear side.

Product Description

OE A1673200302L is a dedicated rear-left air strut assembly with ADS for the latest Mercedes-Benz W167 chassis, the core actuator of factory air suspension system for GLE(V167/C167) and GLS(X167). It integrates high-pressure burst-proof multi-layer air spring, precision hydraulic damper cylinder, OEM-spec ADS solenoid valve and multi-layer composite high-pressure sealing system. It realizes rear load bearing, intelligent ride height adjustment, real-time adaptive damping according to road condition, vibration & noise reduction, high-speed body stabilization, corner anti-roll and rough-road buffer protection. The ADS solenoid valve dynamically adjusts damping stiffness based on vehicle speed, road bumps and load weight, balancing comfortable ride on paved roads, high-speed stability and strong supporting performance under rough roads and full load, fully matching the premium chassis tuning standard of Mercedes luxury SUV.

W167 GLE/GLS features large curb weight and high chassis load, so rear air struts are easy-to-wear spare parts. Subject to vehicle weight, trunk load, continuous road impact, seasonal temperature alternation, dirt and moisture corrosion as well as repeated inflation and deflation cycles, the rubber of original air spring tends to age, harden, crack, bulge and develop slow air leakage. Internal oil seal fatigue failure, hydraulic oil degradation, carbon deposit jamming and signal drift of ADS solenoid valve will trigger fault codes. Typical failure symptoms: rear left sag, vehicle sinks overnight, uneven left-right body height, tilted rear end, frequent air compressor activation, slow or stuck height adjustment, height calibration failure, air suspension / ADS warning light on dashboard, bouncy rear end over speed bumps, floating feeling at high speed, poor body following performance and loose chassis during turning. Long-term driving with defective struts will rapidly damage air compressor, valve block, air dryer and height sensor, leading to cascading breakdown of the whole air suspension system with extremely high repair cost.

This A1673200302L rear left ADS air strut is 1:1 reproduced strictly following Mercedes-Benz OEM data. Stroke dimension, pressure rating, damping coefficient, air spring burst pressure, ADS electronic parameters, mounting holes, bushing interfaces and fixing points fully match OEM standards. It adopts imported thickened multi-layer high-pressure rubber airspring with wide temperature resistance, double anti-leak sealing structure, thickened anti-rust precision piston rod, long-life anti-degradation hydraulic oil and high-sensitivity OEM-grade ADS solenoid valve. Upgraded anti-aging, anti-cracking, anti-corrosion, anti-fatigue and burst-resistant performance fundamentally solves common OEM defects including air leakage, rear sag, weak damping, poor pressure retention at low temperature, abnormal ADS signals and fault codes. This version is dedicated for rear left of W167 chassis; left and right structures are not interchangeable. Direct bolt-on installation without chassis modification. Air tightness inspection, ride height calibration and ADS matching calibration are required after installation, fully compatible with original Airmatic and ADS ECU. It completely repairs rear-left collapse, slow air leakage, abnormal height adjustment, loose chassis, high-speed instability and fault codes, restores tight luxury chassis texture with low rework rate. Ideal for repair shop maintenance, auto parts bulk stocking and cross-border e-commerce sales.

5. FAQ

1. Q1: Which vehicles fit OE A1673200302L? A: Fits Mercedes‑Benz W167 GLE, GLE Coupe and GLS 2019‑Present with factory Airmatic air suspension and ADS adaptive damping. Not applicable for non-ADS air suspension, mechanical springs or old W292/W166 chassis.
2. Q2: Is this strut for rear left or rear right? Can left and right swap? A: This part is exclusively for rear left axle. Rear left and rear right struts differ in structural angle, damping ratio and solenoid matching logic. Interchange is strictly prohibited. Improper mixing will cause tilted rear end, air suspension / ADS fault codes, abnormal height adjustment and unstable chassis.
3. Q3: Can it be installed on vehicles without ADS system? A: Not available. This strut has built-in ADS solenoid valve. Non-ADS vehicles lack corresponding wiring and control unit. Continuous fault codes will pop up and adaptive damping function cannot work normally.
4. Q4: Does computer coding need after replacement? A: No coding required, but air-tightness inspection, ride height calibration and ADS solenoid matching calibration must be performed, clear fault codes before operation.
5. Q5: What symptoms indicate replacement of this rear left strut? A: Rear left sag, vehicle sinks overnight, big left-right height difference, frequent compressor operation, slow stuck height adjustment, air suspension / ADS warning lamp on, bouncy rear end over pits, floating rear end at high speed and loose chassis during turning. These symptoms indicate airspring leakage or ADS solenoid failure, replacement is recommended.
6. Q6: Can I replace only the single rear left strut? A: Pair inspection & replacement is strongly recommended. Old and new struts differ in pressure retention, damping response and ADS sensitivity. Single-side replacement may cause unbalanced rear posture and asymmetric bump performance, affecting comfort and driving safety.
7. Q7: Can interchangeable OE numbers replace each other freely? A: Yes. A1673200302L and its alternative OEs have identical parameters, structure, electronic control and mounting dimensions. They are OEM upgraded replacement parts for direct bolt-on installation.
