Bosch Metzger 0905374 Boost Pressure Sensor, Vehicle-Specific Plastic Part

Getting the most from it

At 6.9 x 4.9 x 4.9 centimetres, this Bosch Metzger boost pressure sensor is a compact, plastic replacement part listed for vehicle-specific fitment. It is intended for vehicle use, so the key buying decision is whether its part references match the one required for your car, rather than whether it will suit vehicles generally.

The listing gives Volkswagen 03K906051 as an OEM-equivalent part number, but also shows 0906138 alongside the product name’s 0905374. Those references do not establish that every version is interchangeable. Before ordering, compare the number on the existing sensor or the part specified for your vehicle with the details supplied by the seller or a parts professional. That matters more here than the sensor’s small size or straightforward description.

For example, if a fault diagnosis points to the boost pressure sensor, this part may be relevant when its vehicle fitment and identifying numbers agree with the required replacement. It is a more targeted purchase than choosing a general-purpose sensor, but it depends on getting the match right.

Pros

The listing provides a clear vehicle-specific fit type and names an OEM-equivalent reference, giving you useful details to compare against the part already fitted. Bosch is the stated brand, and the product is described as a pressure sensor for vehicle use. Its listed weight is 0.03 kilograms, while the stated material is plastic.

These details help narrow down a replacement, but they are not a complete compatibility check. A vehicle-specific part should be selected by matching the required reference and application, rather than by relying on the brand or the broad description alone.

Highlights

The product is listed as one sensor, with a unit count of one. Its compact dimensions may be helpful when identifying the replacement by size, although dimensions alone cannot confirm that it will fit or function correctly in a particular vehicle. The description does not provide further vehicle models, installation instructions or sensor performance figures, so those should not be assumed.

There is also a reference mismatch in the supplied information: 0905374 appears in the product name, while 0906138 is stated as the part number in the features. Volkswagen 03K906051 is presented as an OEM-equivalent number. Treat these as identifiers to verify, not proof that the references can be used interchangeably.

Practical questions

What is this part for? It is listed as a boost pressure sensor for vehicle use. The information does not specify which vehicle models it fits.

Does it fit a Volkswagen? Volkswagen 03K906051 is named as an OEM-equivalent reference, but that alone does not confirm fitment for a particular vehicle. Match the required part number and vehicle application before buying.

Which part number should I check? The product name gives 0905374, while the feature details give 0906138. The listing also names 03K906051 as an OEM-equivalent number, so confirm the correct reference for your vehicle before ordering.

When it makes sense

It’s a good fit if you have identified a need for a boost pressure sensor and can verify that the vehicle-specific application and part references match. The stated OEM-equivalent number gives you a useful cross-check, while the conflicting 0905374 and 0906138 references make confirmation especially important. It’s not for you if you need a broadly compatible sensor without checking vehicle fitment, as the listing explicitly describes this one as vehicle-specific.
