Cheap Mercedes-Benz Vito Power Steering Pump

It depends on the generation. The first-generation Vito (W638, 1996–2003) and second-generation (W639, 2003–2014) used hydraulic power steering, so they do have a physical power steering pump. The third-generation Vito (W447, 2014–present) switched to electromechanical power steering, meaning there is no hydraulic pump to replace on those later vans — if your Vito is a 2014 or newer W447, you should be looking at the steering column or EPS motor instead.

Both a 2006 and a 2011 Vito fall within the W639 generation (2003–2014), so they share the same basic platform, which is a good starting point. However, the W639 was offered with different engine sizes — including 2.1-litre and 3.0-litre diesels — and the pump specification can vary between them, so you need to match the engine as well as the generation. Confirm the exact part number with the breaker against your registration before buying.

Yes, engine size is relevant on the W639 Vito (2003–2014). The 3.0-litre V6 diesel variants can use a different pump specification from the more common 2.1-litre four-cylinder engines, so you cannot assume all W639 pumps are interchangeable. Always tell the breaker your exact engine code or check the part number against your registration to get the right unit.

Trim and equipment grade don't affect the power steering pump fitment — the pump is part of the running gear, not the interior or comfort package. What actually matters is the generation (W638 or W639), the engine size, and the GVW rating of the van, not whether it's badged as a 111 CDI, 116 CDI, or 122 CDI. Confirm the engine code and payload rating with the breaker to make sure the pump specification matches yours.

The W638 and W639 are distinct generations with different engines and steering system layouts, so cross-generation fitment is very unlikely. Mixing parts across that 2003 boundary is not something to attempt based on model name alone. Take the part numbers from both vehicles and run them past the breaker before ordering anything.

The 2015 Vito is a W447 (2014–present), and that generation uses electromechanical power steering with no hydraulic pump. If your steering feels heavy or is giving problems, the fault is likely in the EPS motor, steering column assembly, or a related sensor or control module rather than any pump. A breaker can help you find the correct EPS components once you've had the fault diagnosed against your registration.
