A212 320 0825 Rear Right Air Spring Bag for Mercedes-Benz W212 E-Class / W218 CLS-Class
1. Product Introduction
Original OE Number: A212 320 0825
Product Name: Mercedes-Benz W212 E-Class / W218 CLS-Class Rear Right Air Spring Assembly, Rear Right Air Suspension Bag, Rear Right Air Shock Absorber Bag
Installation Position: Rear right air suspension of the vehicle, Exclusive for rear right, not universal for rear left or front suspension. Suitable for all original Airmatic air suspension models of Mercedes-Benz W212/W218 (universal for standard and AMG high-performance versions). Not applicable for mechanical suspension, front air suspension and other chassis models. This product is a brand-new complete air spring assembly, not a repair kit.
Product Description: A212 320 0825 is an original factory matching rear right air spring assembly for Mercedes-Benz W212 E-Class and W218 CLS-Class, serving as the core replacement part to solve rear right air suspension collapse, air leakage and abnormal noise faults of these models. The rear air suspension of W212/W218 vehicles bears long-term rear load, high-speed shock absorption and bumpy road impact. After years of service, the original rubber air spring is prone to aging and hardening, cracking, bulging and elastic failure, causing typical faults such as rear right vehicle sinking, unbalanced left and right body height, rear sinking after parking, abnormal noise when passing speed bumps at low speed, air suspension warning light alarm, frequent air pump activation, rapid air leakage and pressure relief failure. This product is 1:1 integrally molded according to original factory rear right air suspension parameters, with size, stroke, pressure resistance value, mounting holes and pipeline interfaces fully consistent with original parts, supporting non-destructive in-situ direct replacement. Adopting multi-layer composite weather-resistant high-pressure rubber material, it features excellent aging resistance, high and low temperature 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 and original factory shock absorption texture after installation, completely eliminating rear right air suspension air leakage and collapse faults, serving as a high-cost-performance assembly accessory for repair shop replacement and vehicle maintenance.
Core Advantages
- ✅ 1:1 original factory assembly replication, specially developed for W212/W218 rear right air suspension. The mounting position, telescopic stroke and high-pressure resistance parameters fully match the original vehicle, supporting non-destructive in-situ replacement without modifying original vehicle pipelines and brackets
- ✅ Effectively solves common W212/W218 rear right air suspension faults: aging air spring leakage, rear right sinking, unbalanced body height, bumpy abnormal noise, air suspension fault codes and frequent air pump overload operation
- ✅ 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 winter air leakage, short-term bulging and cracking and short service life, with durability close to original factory quality
- ✅ Direct integral assembly replacement without complicated repair kit disassembly and sealing commissioning, specially suitable for severe faults that cannot be repaired by repair kits, including air spring cracking, damage, delamination, structural air leakage and serious collapse
- ✅ Universal for standard and AMG high-spec W212/W218 rear air suspension, perfectly adapting to the original Airmatic height adjustment electronic control logic. No programming required after installation, only height calibration and fault code clearing needed for normal use with zero error codes and no pressure relief
- ✅ 100% factory tested with high-pressure air tightness test, high and low temperature weathering aging test and heavy-load pressure fatigue test to eliminate defective leakage products, suitable for professional repair shop precision maintenance, 4S shop service and cross-border bulk stocking

5. FAQ
Q1: Is A2123200825 rear left or rear right? Can it be mixed with 0725 (rear left)?
A: This is anexclusive rear right assembly, paired with A2123200725 (rear left). The two are strictly side-specific and cannot be mixed. Wrong installation will cause vehicle body tilt, pressure relief, fault codes and abnormal shock absorption.
Q2: Are standard and AMG versions compatible with this rear right air spring?
A: Fully universal. The installation structure, stroke and pressure resistance parameters of standard and AMG high-spec W212/W218 rear right air springs are completely consistent, supporting direct in-situ replacement.
Q3: Can it be used for front suspension or other chassis models such as W221/W222?
A: No. The structure, stroke and working pressure of front and rear air springs are vastly different. This product is exclusively designed for W212/W218 rear right position and not compatible with other chassis models.
Q4: When should I replace the assembly instead of using a repair kit?
A: Replace the whole assembly directly when the original air spring has cracks, bulges, delamination, damage, structural collapse, rapid air leakage or aging and peeling outer skin. Repair kits are only applicable for slight slow air leakage with intact air spring bladder.
Q5: Is computer programming required after installation?
A: No programming or coding required. After in-situ replacement, only air tightness testing, 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 OE numbers are original factory iterative upgraded models with completely consistent assembly size, performance, vehicle adaptability and installation parameters, only different in factory batch coding, which can be replaced freely.
