A2213204913 Front Air Suspension Repair Kit for Mercedes-Benz W221 S-Class
1. Product Introduction
Original OE Number: A221 320 4913
Product Name: Mercedes-Benz W221 S-Class Front Air Suspension Repair Kit, Front Air Spring Sealing Repair Kit
Installation Position: Front air suspension system, universal for front left and front right, not compatible with rear positions. Exclusively suitable for Mercedes-Benz W221 chassis S-Class models with original Airmatic air suspension. Not applicable for mechanical suspension, rear air suspension, hydraulic suspension and other chassis models. Only for minor sealing air leakage repair of front air suspension.
Product Description: A221 320 4913 is an original factory matching special repair kit for the front air suspension of Mercedes-Benz W221 S-Class high-end flagship models, a high-demand accessory for repairing slight air leakage and sealing aging of W221 front air suspension on the market. The W221 S-Class features a comfort-oriented chassis tuning. The front air suspension bears long-term load from front vehicle weight, urban bumpy roads and high-speed cruising. With the increase of service life, the sealing cups, dust-proof rubber rings and sealing components of the original air spring are prone to aging, hardening and elastic deformation, causing common faults such as chronic micro air leakage, front sinking after parking, unbalanced left and right body height, chassis abnormal noise when passing speed bumps at low speed, occasional air suspension warning light and frequent air pump startup. This repair kit adopts 1:1 replication of original factory sealing size and pressure resistance parameters, including a full set of special sealing rubber rings, dust-proof repair components and high-pressure sealing accessories. There is no need to replace the expensive front air spring assembly, which can accurately repair minor faults such as poor air suspension sealing, slight pressure relief and slow air leakage. Made of high-elastic sealing material resistant to high and low temperatures, it features excellent aging resistance, high pressure resistance and deformation resistance, ensuring stable air tightness after repair. It is a cost-effective accessory for low-precision professional repair in repair shops and long-term vehicle maintenance.
Core Advantages
- 1:1 replication of original A2213204913 sealing parameters, with accessory size, installation position and sealing accuracy fully matching original W221 front air springs. Universal for front left and right, supporting non-destructive maintenance without modifying original vehicle pipelines and brackets
- Specially solves typical W221 S-Class front air suspension faults: sealing aging pressure relief, slight slow air leakage, front sinking after parking and unbalanced body height, perfectly adapting to complex working conditions such as long-term commuting and seasonal temperature aging of high-end vehicles
- Adopts luxury vehicle-specific high-elastic weather-resistant sealing material, resisting hardening, deformation and high-pressure fatigue, avoiding secondary air leakage and sealing failure of ordinary low-cost repair kits for longer service life after repair
- Economical and accurate maintenance solution, no need to replace the air spring assembly, only replace aging sealing parts to repair minor air leakage faults, greatly reducing maintenance costs and avoiding excessive maintenance
- Fully compatible with Mercedes-Benz W221 original Airmatic intelligent air suspension electronic control system. After repair, the vehicle body automatic leveling is accurate, height data is normal with no fault codes, restoring the original factory comfortable chassis texture
- Every product undergoes strict factory tests including air tightness detection, high and low temperature aging test and high-pressure resistance test, featuring high fitting accuracy and low error rate, suitable for 4S shop maintenance, professional repair shop precision overhaul and cross-border bulk stocking

5. FAQ
Q1: Is A2213204913 front repair kit universal for front left and front right?
A: Fully universal. The W221 S-Class front air suspension repair kit has no left or right distinction, which can be used for both front left and front right air spring maintenance without position distinction.
Q2: Can it be used for rear suspension or W220/W222 new S-Class models?
A: No. The sealing structure and stroke parameters of front and rear air suspensions are vastly different, and it cannot be used for rear suspension. It only fits W221 chassis exclusively, not applicable for other generations of S-Class and other chassis models.
Q3: Is it suitable for mechanically suspended models?
A: No. Mechanical suspension models have no air suspension structure and air suspension sealing components, with no maintenance conditions.
Q4: Is computer programming required after replacement?
A: No programming and coding required. Adopting original standard sealing parameter adaptation, only air tightness test, body height calibration and fault code clearing are needed after repair for normal use.
Q5: When to use a repair kit and when to replace the assembly?
A: The repair kit is applicable to vehicles with slight chronic air leakage, front sinking after parking, sealing aging pressure relief and slight unbalanced body height, while the air spring bladder is complete without cracking, bulging and deformation. If the air spring has structural damage, large-area air leakage and serious collapse, replacing the air spring assembly is recommended.
Q6: What is the difference between multiple interchangeable OE numbers?
A: All interchangeable OE numbers are original factory batch iteration upgrade models with completely consistent sealing performance, accessory specifications and vehicle adaptability, only different in coding and can be interchanged freely.
