Audi Air Suspension Valve Block: Models, OE Numbers, Fitment

If you are matching an Audi air suspension valve block, start with the OE number and the platform code — not the model name alone. HUIJIE's Audi Q7 4M valve block is listed for 2018–2022 Q7 models; confirm the exact OE number against the product record before ordering, because A6, A8 and older Q7 applications use different part-number families.

• Match Audi valve blocks by OE number, platform code and model year together; the model name alone is not enough.
• HUIJIE's Q7 4M valve block is listed for Audi Q7 2018–2022, and the OE reference 4M0616013A for it is unverified in the available product listing.
• Retrieved listings separate Audi valve blocks into different OE families: 4H numbers for some A6, A7 and A8 D4 claims, 4N and 80A numbers for A6 C8/4K, and 7L0698007 in a broader Q7 2006–2016 listing.
• A valve block distributes compressor air to the air springs and controls inflation and deflation flow; a four-to-six-outlet layout is a general system description, not an Audi specification.
• HUIJIE lists a 1-year warranty and ISO 9001:2015, CE and IATF certification, but fitment still has to be confirmed by OE number.

What an Audi air suspension valve block does and where it sits

An Audi air suspension valve block is the component that distributes compressor-generated air to the air springs and controls when that air flows in or out. According to HUIJIE's guide to the automotive air suspension valve block, the part distributes air between system components and controls the flow through solenoid-operated channels. Vigor Air Ride's guide dated March 28, 2024 describes the same role as regulating when and how quickly air inflates or deflates the air springs.

Within the wider system, the block sits between the compressor and reservoir on one side and the pneumatic lines and air struts on the other. AirSuspension.com's valve block category describes units with four to six outlets, covering the suspension corners plus connections to the compressor and reservoir. That outlet count is a general system description rather than an Audi specification, so the configuration for a specific platform should be confirmed before ordering.

Audi Q7 4M valve block: featured application and OE verification

HUIJIE's valve block for the Audi Q7 4M is listed for Q7 model years 2018–2022, according to the product listing for the audi q7 4m suspension valve block. The OE reference 4M0616013A supplied for this application is not confirmed by that retrieved listing, so treat it as unverified until HUIJIE confirms it against your exact vehicle.

Verify the OE number before you order

Do not rely on the model name alone, even when the year range appears to match. Ask HUIJIE to confirm the OE number against the exact Q7 4M product record, or supply the vehicle identification number, model year and platform code so the application can be checked against the part that is actually supplied.

Audi A6, A8 and older Q7 applications: separate platforms, separate OE families

Retrieved Audi valve-block listings group applications into distinct OE families — 4H numbers for some A6, A7 and A8 D4 claims, 4N and 80A numbers for A6 C8/4K, and 7L0698007 in a broader Q7 2006–2016 listing — so match by platform and OE number rather than by model name. The table below records only what each source states, together with its verification status.

These rows are compatibility claims made by the sellers named beside them, not a statement that the parts interchange. Do not assume that Q7 4M, Q7 4L, A6 and A8 valve blocks are interchangeable unless HUIJIE product data or vehicle manufacturer data confirms the exact platform and OE pairing. The HUIJIE Touareg valve-block listing that covers Audi Q7 2006–2016 identifies 7L0698007 in its product title; it does not specifically confirm Q7 4L, so request confirmation if that is your platform.

How to match an Audi air suspension valve block by OE number

Start with the OE number on the original valve block, then confirm the platform, model year and suspension variant against the replacement listing. If any of those fields is missing, the model name on its own is not enough to place an order.

1. Locate the OE number on the original valve block or in the vehicle parts record.
2. Identify the platform code — for example Q7 4M, Q7 4L, A6 C7/4G or A6 C8/4K.
3. Compare the OE number, its suffix and the listed model years against the replacement product.
4. Check connector and fitting details wherever the listing publishes them, since these differ between number families.
5. If the OE number or platform is uncertain, send HUIJIE the vehicle identification number, model year, platform code and a photo of the original part.

Part naming adds a further source of confusion: the same component is sold as a suspension solenoid valve block and as a suspension control valve block. Whichever name a listing uses, the OE number and platform decide fitment. In the AIRSUSFAT marketplace listing, one product carries several 4H and 3Y numbers, and Rebuild Master Tech lists two references, 4N0616013 and 80A616013, for a single A6 application — so the suffix matters.

Symptoms and checks before replacing an Audi valve block

A faulty valve block can contribute to uneven ride height or air-flow problems, but symptoms alone do not prove the valve block is the failed part. Vigor Air Ride's March 28, 2024 guide covers leakage checks and troubleshooting, and AirSuspension.com's valve block category covers common failure causes and selection considerations.

No model-specific Audi symptom sequence is stated here, because none was available from the cited sources. If ride height is uneven, confirm the fault and the part number before ordering a replacement rather than replacing the valve block on suspicion.
