A2113200925 Rear Spring Air Bags For Mercedes-Benz W211 E-Class / W219 CLS-Class 4Matic

A211 320 0925 Rear Air Spring Bag for Mercedes-Benz W211 E-Class / W219 CLS-Class 4Matic

1. Product Introduction

Original OE Number: A211 320 0925

Product Name: Mercedes-Benz W211 E-Class / W219 CLS-Class Rear Air Spring Assembly, Rear Air Suspension Bag, Rear Air Shock Absorber Bag (4MATIC Four-Wheel Drive Exclusive, Universal for Rear Left/Right)

Installation Position: Rear air suspension of the vehicle, Exclusive for 4WD, Universal for rear left and right, Not universal for front suspension or 2WD models. Suitable for Mercedes-Benz W211/W219 original 4MATIC four-wheel drive Airmatic air suspension models. Not applicable for 2MATIC two-wheel drive, mechanical suspension, front air suspension and other chassis models. This product is a brand-new complete air spring assembly, not a repair kit or individual sealing accessory, which directly solves structural air leakage and collapse faults of 4WD rear air suspension.

Product Description: A211 320 0925 is an original factory exclusive rear air spring assembly for Mercedes-Benz W211 E-Class and W219 CLS-Class 4MATIC four-wheel drive models, serving as the core replacement part to solve common faults such as rear sagging, body tilt, slow air leakage and aging failure of rear air springs on 4WD vehicles. 4WD vehicles have larger body weight and higher rear load, and the rear air suspension operates under long-term high-intensity bumping and telescopic conditions. The original rubber air spring is prone to aging and hardening, surface cracking, bulging, delamination and elastic attenuation, resulting in typical problems including rear sagging after parking, unbalanced rear left/right body height, chassis abnormal noise over bumps, persistent air suspension warning light, frequent air pump operation, slow pressure relief and loose bouncing at high speed. This product adopts 1:1 replication of original factory 4WD rear air suspension structural parameters, specially matching the telescopic stroke, pressure resistance, mounting base and pipeline interface of 4WD chassis, which is completely different from the structure and size of 2WD air springs. It supports non-destructive in-situ direct replacement without modifying any original vehicle structure. Adopting multi-layer thickened composite weather-resistant rubber with built-in high-strength pressure-resistant fiber layer, it features excellent high and low temperature resistance, aging resistance and high-pressure fatigue resistance with long-term stable air tightness. Fully compatible with the original Airmatic electronic control system, it ensures accurate body height, comfortable shock absorption and firm support after installation, completely eliminating air leakage and collapse faults of 4WD rear air suspension. It is a high-cost-performance assembly accessory for professional repair and batch replacement in repair shops.

Core Advantages

• ✅ 1:1 original factory 4WD exclusive replication, precisely matching W211/W219 4MATIC four-wheel drive rear air suspension, universal for rear left and right with fully consistent parameters, stroke, pressure resistance and hole positions for non-destructive in-situ replacement
• ✅ Effectively solves exclusive faults of 4WD models: air spring aging and leakage, rear sagging, unbalanced body height, bumpy abnormal noise, air suspension fault codes, frequent air pump overload operation and rear pressure relief after parking caused by 4WD heavy load
• ✅ Multi-layer thickened high-strength rubber + fiber pressure-resistant structure, optimized fatigue resistance for 4WD heavy-load working conditions, eliminating common defects of ordinary aftermarket air springs such as bulging, cracking, short-term air leakage and insufficient support, with service life close to original factory quality
• ✅ Direct integral assembly replacement without complicated repair kit maintenance, specially suitable for severe faults that cannot be repaired by repair kits, including air spring damage, delamination, structural air leakage, serious collapse and rubber hardening failure
• ✅ Fully compatible with original Airmatic 4WD air suspension electronic control system, no programming required after installation, only height calibration and fault code clearing needed for normal use with zero error codes and stable pressure
• ✅ 100% factory tested with high-pressure air tightness test, high and low temperature weathering test and heavy-load fatigue test, featuring stable quality and ultra-low rework rate, suitable for 4S shop maintenance, professional repair shops and cross-border bulk stocking

5. FAQ

Q1: Does A2113200925 distinguish left and right?

A: No left/right distinction. This is a universal rear air spring assembly for W211/W219 4WD models, applicable for both rear left and rear right positions for direct replacement.

Q2: Is it applicable for 2MATIC two-wheel drive models? Is it universal with 0725/0825?

A: Completely non-universal. This product is exclusive for 4WD. The structure, stroke, pressure resistance value and base size of 2WD rear air springs are totally different. Forced installation will cause poor sealing, continuous air leakage, fault codes and insufficient support leading to rear sagging.

Q3: Are W211 and W219 4WD models universal?

A: Fully universal. The rear air spring parameters of W211 E-Class and W219 CLS-Class 4WD models are consistent, supporting direct in-situ replacement.

Q4: When to replace the assembly instead of using a repair kit?

A: Assembly replacement is mandatory when the original air spring has outer skin cracking, bulging, delamination, damage, structural collapse, rapid air leakage and rubber hardening & loss of elasticity. Repair kits are only applicable for slight slow air leakage with intact air spring skin.

Q5: Is computer programming required after installation?

A: No programming or coding required. After in-situ replacement, only air tightness testing, rear body height calibration and fault code clearing are needed for normal use, and the original electronic control system adapts automatically.

Q6: What is the difference between interchangeable OE numbers?

A: All interchangeable OEs are original factory iterative upgraded batches with completely consistent assembly size, performance and 4WD adaptation parameters, only different in factory batch coding, which can be replaced freely.
