Mercedes Air Suspension Valve Block: Models and Fitment

HUIJIE lists Mercedes-Benz AIRMATIC valve blocks by chassis and OE number, covering W211, W220 S-Class and W222 applications, each identified by its reference number rather than by model name alone. This page shows which listed part matches which chassis, and how to confirm fit by comparing the OE number on your removed valve block with the listing before you order.

Key takeaways

• Who this is for: distributors, wholesalers and repair shops sourcing Mercedes-Benz AIRMATIC valve blocks by chassis and OE number.
• Chassis coverage: HUIJIE listings identify a W220 S-Class valve block by OE number 2203200258 and a W222 AIRMATIC valve block by reference 993200058.
• Unconfirmed fields: no W211 OE number and no complete model-year range is confirmed for the three chassis listed here, so those cells stay open until they are checked against the product record.
• Ordering rule: match the OE number on the removed part first, then confirm chassis, model, body style and year.
• Brand note: HUIJIE is an air suspension parts manufacturer based in Sichuan, China, with more than 2,000 products listed and a 1-year warranty.

Which Mercedes models use an AIRMATIC valve block?

Mercedes-Benz air suspension valve blocks belong to AIRMATIC-equipped vehicles, and Mercedes-Benz's used-parts catalogue attaches its air suspension valve block listing to equipment code 489, described there as "AIRMATIC DC / AIR SUSPENSION SEMI-ACTIVE". That catalogue entry is snippet-level evidence, so treat code 489 as an identifier used by that catalogue rather than as a rule that covers every Mercedes-Benz valve block.

An air suspension valve block is the component that distributes compressed air between the consumers in an air suspension system. The W220 Wiki Airmatic reference identifies the level control valve unit as Y36/6 and describes it as connected to a computer that monitors air pressure, vehicle height requirements and stance. This page covers HUIJIE's listed Mercedes fitments for W211, W220 S-Class and W222, and the air suspension valve block category guide sets out the component's role across the wider range.

Mercedes air suspension valve blocks by chassis

HUIJIE's listings confirm one chassis-specific identifier for the W220 S-Class and one for the W222, while the W211 entry carries no OE number confirmed on this page and is marked for confirmation. The table shows what is confirmed and what still has to be checked before an order.

W211 E-Class valve block

The W211 valve block must be matched by OE number against the live product record, because no W211 OE number is confirmed on this page. Read the number off your removed valve block, open the mercedes w211 valve block record, and compare the two character by character. If the record does not show a number you can match, treat the fitment as unconfirmed and ask for verification.

W220 S-Class valve block

HUIJIE's W220 listing identifies OE number 2203200258 for a W220 S 350 Sedan application, so that number is the reference to compare against your removed part on the mercedes s class valve block record. The listing's year text is incomplete, so no full model-year range is stated here; check the year against the listing when you order.

W222 AIRMATIC valve block

HUIJIE's W222 listing identifies reference number 993200058 for a W222 AIRMATIC valve block on the w222 airmatic valve block record. The listing states no model-year range, so none is claimed here — check both the number on your removed valve block and the vehicle details before ordering.

How to confirm the right valve block by OE number

Confirm fit by reading the OE number off the removed valve block, comparing it with the number shown on the HUIJIE listing, then confirming the vehicle details. Work through the steps in this order:

1. Locate and photograph the OE number on the removed valve block.
2. Open the chassis product record and compare the listed number with the photographed number.
3. Check the vehicle's chassis code, model and body style against the listing.
4. If the numbers differ, or the listing states no model year, pause and request confirmation.

A matching chassis code is not a fitment guarantee on its own. Send these details with an enquiry: the OE number from the removed part; the chassis code (W211, W220 or W222); model and body style; model year; and the vehicle identification number (VIN) if your supplier's process asks for it.

Why the chassis code alone is not enough

A Mercedes-Benz chassis code covers several model years, body styles and suspension builds, so it cannot separate an AIRMATIC-equipped car from a non-AIRMATIC one by itself. Mercedes-Benz's used-parts catalogue attaches its valve block listing to equipment code 489 rather than to a chassis alone. Use this order: the OE number is the primary matching field, the chassis code narrows the search, and model, body style and year settle the final match. Do not substitute one field for another.

Order the Mercedes valve block that matches your number

HUIJIE is an air suspension parts manufacturer based in Sichuan, China, with more than 2,000 products listed, so if your chassis appears above but your OE number does not, send the number from your removed part together with the vehicle details and ask for confirmation before ordering. HUIJIE supplies OEM and aftermarket buyers worldwide, including distributors, wholesalers and repair shops.

FAQ

What are common signs of a failing Mercedes AIRMATIC valve block?

Faults owners notice, such as a car sitting low at one corner or failing to raise, can come from the valve block, but also from a compressor, air spring, strut or ride-height sensor. The W220 Wiki Airmatic reference treats these as system-level checks. Because the symptoms overlap, test the system before replacing the valve block.

Is equipment code 489 relevant when choosing a valve block?

Equipment code 489 is attached to the valve block listing in Mercedes-Benz's used-parts catalogue, which describes it as "AIRMATIC DC / AIR SUSPENSION SEMI-ACTIVE". It identifies that catalogue's listing rather than setting a universal rule for every Mercedes-Benz valve block, so match your part by OE number rather than by code alone.

Are W211, W220 S-Class and W222 valve blocks interchangeable?

No interchangeability between the W211, W220 S-Class and W222 valve blocks is claimed here. HUIJIE's listings carry different references for the W220 part, 2203200258, and the W222 part, 993200058, and no W211 OE number is confirmed on this page. Treat each chassis as a separate fitment and match the number on your removed valve block.
