A0022307311 12V 6PK AC Compressor for Mercedes-Benz W212 E350 3.5L V6

What the W212 AC Compressor Does in the Mercedes E350

The W212 AC compressor is the part that makes the air conditioning work in the 2012–2013 Mercedes E350. Driven by the engine belt, it pressurises the refrigerant and keeps it moving through the system, and without it the rest of the A/C system has nothing to do. This unit is our replacement for the compressor listed under OE A0022307311 for the E350’s 3.5L V6.

When the fault is inside the compressor, the car stops cooling and the workshop replaces the whole unit rather than repairing it. That is the job this compressor is made for: a complete, new unit that goes straight onto the car.

W212 AC Compressor Specifications: A0022307311

This W212 AC compressor is a new 12V unit with a 6PK pulley, referenced to OE A0022307311 and fitting the 2012–2013 Mercedes E350 with the 3.5L V6. Use the details below to match it to the enquiries you receive and to list it correctly in your own catalogue.

Which Mercedes E350 Models Does This W212 AC Compressor Fit?

This W212 AC compressor fits the petrol Mercedes-Benz E350 with the 3.5L V6: the 2012 and 2013 sedan and wagon, and the 2012 coupe and convertible. It does not fit the E350 BlueTEC diesel, or the 2013 E350 coupe and convertible, which use different compressors, and other W212 E-Class versions such as the four-cylinder, V8 and AMG models are not covered by this listing. We have not confirmed E350 model years after 2013. For other E350 applications we also list the CL-RT61001S 6SEU16C compressor for Mercedes-Benz E350 and ML350, and more Mercedes-Benz models are covered in our wholesale auto AC compressors range. To check a particular model year or version, contact our sales team or send your vehicle list through the inquiry form.

Why the Mercedes E350 W212 AC Compressor Is Worth Sourcing

The W212 AC compressor for the Mercedes E350 is worth sourcing because it serves a well-sold premium car that has now reached the age when compressors fail, and whose owners keep their air conditioning working. That combination keeps replacement enquiries coming from the workshops you supply.

A large base of E-Class cars. Mercedes-Benz sold nearly 140,000 E-Class cars in the United States in 2012 and 2013 alone, according to GoodCarBadCar’s sales records. The petrol E350 sedan and wagon covered by this compressor are part of that total, alongside other versions that use different compressors.

Cars at the age when compressors fail. The average light vehicle in the United States reached a record 12.8 years in 2025, according to S&P Global Mobility, and the 2012–2013 E350 is now past that age. Once these cars leave dealer service, owners usually turn to independent workshops for repairs, and those workshops source their parts from distributors.

Owners who expect the A/C to work. A Mercedes E-Class buyer expects a comfortable cabin, and in hot markets a car without working air conditioning is hard to drive for much of the year. A failed compressor is repaired rather than left, so demand follows the cars wherever they are common.

Finding a Reliable Supplier for Mercedes-Benz Compressor Orders

With steady demand behind these cars, the next question is a supplier who keeps your workshop customers happy without taking up your time. Every W212 AC compressor we ship is tested on our own line first, not a sample from the batch, so fewer units come back from workshops. Tell us which cars your customers bring in, and we will tell you which compressors, A/C compressor clutches, automotive AC expansion valves and control valves fit them, such as our CL-2008 AC compressor control valve for Mercedes-Benz, and which are not worth your money.

If some models on your list are ones we don’t make, send us the full list anyway. With more than 15 years in this industry, we know China’s supply market well. We find the product that fits your requirement, explain how the available versions differ in material and price, including when the cheaper one is enough for your customers, and check each one again using our own production experience before it ships together with the rest of your order. You start from 20 pieces per model, with different models in one order, and you get the parts you need with the least effort, through one supplier and one contact.

How Is Every W212 AC Compressor Tested Before Shipment?

Every W212 AC compressor we supply for the Mercedes E350 is tested on our own testing line before it is packed, and every unit goes through it, not a sample from the batch. Each compressor is checked for damage and against the order, leak-tested at the housing joints, shaft seal and refrigerant ports, and checked for clutch engagement and electrical insulation. After a bench run, the OE reference, label and quantity are checked once more, and the refrigerant ports are capped before packing.

The bench run is the step that matters most. A compressor can turn freely by hand and still fail once it is under load, so every unit runs on a test bench that reproduces the temperature and pressure it will face in the E350’s A/C system, while we check pressure build-up, stable running, noise and vibration. Faults that a quick static check would miss are caught here, not after a workshop has fitted the unit, refilled the system and handed the car back, so fewer units come back to you as claims.

What Happens If Something Goes Wrong With an Order?

We don’t avoid responsibility, and you don’t have to prove whose fault it is before we act. Send us the order reference, how many pieces are affected, the vehicle, and photos or a short video; if you only have part of that, send what you have. You get a first reply within about two hours of our working day. Before anyone discusses the cause, our sales team works through the immediate problem with you: what your customer is waiting for, where the affected goods are, and what you have already promised. That way you have an answer for your own customer straight away.

Once the immediate problem is handled, we check the cause step by step: whether the right compressor was supplied, the product and its transport, the installation, and the rest of the car’s A/C system. We don’t call it a product fault or an installation fault until every step is checked, so the result holds up when you pass it on. We then tell you what we found and whether the rest of the order can stay on sale. Our sales team follows up with you directly to agree the final solution.

Build a Purchase Plan for Your Market

Tell us a little about your market, and we will put together a purchase plan for this W212 AC compressor: whether it suits regular repeat orders or works better as one line in a mixed order, what makes sense for a first order, and which other Mercedes-Benz models are worth adding for the same customers. Every unit in that plan is tested before it ships, and any model we don’t make is sourced and checked for you.

To build the plan, three basic details are enough: the OE number or vehicle, the country you sell into, and the quantity you have in mind. If you can also share what the purchase is for, such as reordering a part that already sells or building a wider Mercedes-Benz range, and what you want the project to achieve, the plan can go further than a single price.

If you are not yet sure what to include, our sales team is available to talk it through. We will take the time to understand your situation and recommend the approach that suits your business best.
