A211 320 0725 Rear Left Air Spring Bag for Mercedes-Benz W211 E-Class / W219 CLS-Class 2Matic
1. Product Introduction
Product Name: Mercedes-Benz W211 E-Class / W219 CLS-Class Rear Left Air Spring Assembly, Rear Left Air Suspension Bag, Rear Left Air Shock Absorber Bag (2MATIC Two-Wheel Drive Exclusive)
Product Description: A211 320 0725 is an original factory matching rear left air spring assembly for Mercedes-Benz W211 E-Class and W219 CLS-Class 2MATIC two-wheel drive models, serving as the core replacement part to solve rear left air suspension collapse, air leakage, body tilt and rear sagging faults. The rear air suspension of W211/W219 vehicles bears long-term rear load, road bump impact and high-speed shock absorption. After years of service, the original rubber air spring is prone to aging and hardening, cracking, bulging, delamination and elastic failure, causing typical faults such as rear left sinking, unbalanced left and right body height, rear sagging after parking, abnormal noise when passing speed bumps at low speed, persistent air suspension warning light, frequent air pump operation, slow air leakage, rapid pressure relief and loose chassis bouncing. This product is 1:1 integrally molded according to original factory 2MATIC rear left air suspension parameters, with air spring size, telescopic stroke, high-pressure resistance value, mounting holes and pipeline interfaces fully consistent with original parts, supporting non-destructive in-situ direct replacement without modifying original vehicle structure. Adopting multi-layer thickened composite high and low temperature resistant rubber material with built-in high-strength pressure-resistant fiber layer, it features excellent aging resistance, crack resistance and high-pressure fatigue resistance with superior air tightness. Fully compatible with the original Airmatic intelligent air suspension electronic control system, it ensures accurate body height, comfortable shock absorption and stable support after installation, completely eliminating rear left air suspension air leakage and collapse faults. It is a cost-effective original-level assembly accessory for repair shop maintenance and vehicle replacement.
- ✅ 1:1 original factory assembly replication, specially developed for W211/W219 2MATIC two-wheel drive exclusive rear left air suspension. Strictly distinguished for left/right and 2WD/4WD positions, with fully consistent mounting position, stroke and pressure resistance parameters for non-destructive in-situ replacement
- ✅ Effectively solves common 2WD rear left air suspension faults: aging air spring leakage, rear left sinking, unbalanced body height, bumpy abnormal noise, air suspension fault codes, frequent air pump overload operation and rear sagging after parking
- ✅ Adopts multi-layer thickened imported rubber + high-strength pressure-resistant fiber structure, no hardening at low temperature and no softening at high temperature, eliminating the defects of ordinary aftermarket air springs such as bulging, cracking, short-term air leakage and short service life, with durability close to original factory quality
- ✅ Direct integral assembly replacement without complicated disassembly and sealing commissioning, specially suitable for severe faults that cannot be repaired by repair kits, including air spring damage, structural air leakage, serious collapse and aging failure
- ✅ Fully compatible with original Airmatic 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 to eliminate defective leakage products, with stable quality and ultra-low rework rate, suitable for 4S shop maintenance, professional repair shops and cross-border bulk stocking

5. FAQ
A: This is an exclusive 2WD rear left air spring assembly, paired with A2113200825 (rear right). The left and right structures are non-universal and cannot be interchanged. Wrong installation will cause vehicle tilt, pressure relief air leakage, fault codes and abnormal shock absorption.
A: No. This product is exclusive for 2MATIC two-wheel drive. The structure, stroke and mounting base of 4WD rear air suspension are completely different and not universal.
A: Fully universal. The rear left air spring parameters of W211 E-Class and W219 CLS-Class 2WD models are consistent, supporting direct in-situ replacement.
A: Assembly replacement is mandatory when the original air spring has outer skin cracking, bulging, delamination, damage, structural collapse, rapid air leakage and aging peeling. Repair kits are only applicable for slight slow air leakage with intact air spring skin.
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.
A: All interchangeable OEs are original factory iterative upgraded batches with completely consistent assembly size, performance, vehicle adaptability and installation parameters, only different in factory batch coding, which can be replaced freely.
