Product Description

4H0616013A / 4H0616013B is an original-equipment-grade dedicated air suspension distribution valve for Audi high-end chassis, specially designed for Audi A6L C7, A7, A8 D4, S6, S7, S8 high-end models equipped with factory original air suspension. As the pressure control core of the air suspension system, it is mainly responsible for four-wheel independent air pressure distribution, system pressure stabilization and retention, intelligent vehicle body height adjustment, and automatic pipeline pressure balance. It accurately controls the air inflation, pressure retention and pressure relief logic of the four air springs, serving as the core part to solve common faults such as air suspension sagging, body tilting and unbalanced height of old Audi high-end vehicles.

The original distribution valve of Audi C7/D4 series works in long-term harsh chassis environments with high humidity, large temperature differences and frequent high-pressure operation. After years of use, it is prone to internal solenoid valve sticking, valve core carbon deposition, aging and cracking of sealing rubber rings, micro valve pressure relief, pressure retention failure and unbalanced shunting. Typical vehicle faults include single-side or four-wheel body sagging after overnight parking, unbalanced left-right body height, frequent continuous operation of the air suspension compressor, slow chassis lifting speed, lifting stuttering, body shaking and tilting during driving, dashboard air suspension warning light on, and system pressure leakage and pressure relief fault codes.

This distribution valve is 1:1 precisely replicated according to original factory parameters of 4H0616013A and 4H0616013B. The valve flow channel aperture, solenoid switching frequency, high-pressure resistance grade, electronic control signals, plug pin definitions and pipeline interface dimensions fully comply with OEM standards. Adopting high-strength aluminum alloy valve body, high and low temperature resistant high-pressure fluororubber sealing kit and anti-interference precision electronic valve core, it features sensitive response, accurate pressure stabilization, stable pressure retention, corrosion resistance and aging resistance. It supports non-destructive in-situ direct installation without wiring modification, drilling or professional programming, perfectly compatible with the original Airmatic air suspension control system. It thoroughly solves stubborn faults of Audi A6C7/A7/A8D4 including air suspension body sagging, pressure leakage, overworked compressor, body tilting and abnormal lifting with an ultra-low rework rate, being a popular essential part for auto repair replacement, parts wholesale and cross-border export.

Core Advantages

• ✅ 1:1 OEM precise replication, perfectly matching all Audi C7/D4 air suspension models with zero deviation in hole position, flow channel and electronic signal
• ✅ Solves classic Audi high-end air suspension faults: static body sagging, body tilting, pressure leakage, frequent compressor operation and system alarm
• ✅ Precision high-pressure valve structure, anti-carbon deposition, anti-sticking and aging-resistant, maintaining leak-free and stable pressure under long-term high-pressure operation
• ✅ Universal for all vehicle positions and multiple models, simple inventory management with low stock pressure
• ✅ Non-destructive bolt-on installation, no modification or coding required, only code clearing and leak test for ultra-high installation success rate
• ✅ Restores four-wheel independent pressure stabilization and shunting function, corrects body level errors and recovers original high-end chassis comfort

Compatibility Instruction: This product is a dedicated air suspension distribution valve for Audi C7/D4 high-end chassis, universal for multiple models. It only fits high-end models equipped with factory Airmatic air suspension. Mechanical and hydraulic suspension models have no matching air suspension pipelines and electronic control structures, resulting in incompatibility.

Exact Compatible Models List

1. Audi A6L C7: All air suspension versions (2011–2018)
2. Audi A7: All air suspension versions (2011–2018)
3. Audi A8L D4: All air suspension versions (2011–2018)
4. Audi Performance Versions: S6, S7, S8 corresponding air suspension models

Applicable Years: 2011–2018

Main OE Numbers: 4H0616013A, 4H0616013B

Interchangeable OE Numbers: 4H0616013, 4H0616013C, 4H0616013D

Interchange Remark: The above numbers are factory upgraded iterative replacement parts with 100% identical valve flow channel structure, pressure resistance parameters, electronic signals, mounting interfaces and sealing specifications. They are fully universal distribution valve assemblies, supporting direct non-destructive interchangeable installation without modification or programming, zero compatibility faults.

Q1: Are 4H0616013A and 4H0616013B fully interchangeable?

A: Completely universal. They are different batch upgrade numbers for the same factory valve with fully consistent size, function, parameters and compatible models, freely interchangeable for installation.

Q2: Does this distribution valve fit specific front/rear/left/right positions?

A: No position limitation, universal for all A6C7/A7/A8D4 air suspension models, featuring simple inventory management and wide compatibility.

Q3: Is it suitable for low-config mechanical suspension models?

A: No. This part is exclusively applicable to high-end models with factory-built air suspension system. Mechanical chassis has no matching air suspension pipelines and control modules, resulting in incompatibility.

Q4: Is it compatible with new A6 C8 and A8 D5 models?

A: Not universal. This valve is exclusive for old 2011–2018 C7/D4 chassis. New chassis has different valve structure and electronic control logic and cannot be mixed.

Q5: Is programming required after distribution valve replacement?

A: No programming or coding required. After in-situ replacement, exhaust pipeline air, complete air tightness test, clear fault codes and calibrate body height for normal use, the vehicle system will adapt automatically.

Q6: What faults require direct distribution valve replacement?

A: Direct replacement is recommended for vehicle static sagging, single-side sinking, unbalanced left-right height, frequent compressor operation, slow and stuttering lifting, air suspension warning light and system pressure relief faults. These problems are mainly caused by valve sticking and sealing aging failure, which can be completely solved by replacing the new assembly.
