BMW 1 3 Series E46 E87 E90 E91 Petrol N46 N46N Eccentric Shaft Sensor 7513783

BMW 1 3 Series E46 E87 E90 E91 Petrol N46 N46N Eccentric Shaft Sensor is a specialized component of the timing control system, used in BMW E46, E87, E90, and E91 power units. It is responsible for the precise reading of the eccentric shaft position, which has a direct impact on the operation of the variable valve timing system and engine stability. Thanks to the use of the original BMW design, this eccentric shaft sensor ensures proper cooperation with the control electronics and engine control unit software.

Purpose and function in the N46/N46N petrol engine

The presented component is designed for BMW petrol engines from the N46/N46N family installed in the 1 and 3 series models of the E46, E87, E90, and E91 generations. The sensor monitors the position of the eccentric shaft responsible for controlling valve lift and then transmits the signal to the engine control unit. A correct reading of this signal is crucial for:

• stable idle speed,
• proper air-fuel mixture dosing,
• efficient operation of the variable valve timing system,
• reducing power drops and jerking during acceleration.

Thanks to proper cooperation with the control system, the eccentric shaft sensor helps maintain the engine's performance and reduces the risk of errors appearing in the controller's memory.

Benefits of using an original BMW sensor

Using an original BMW solution instead of a worn or damaged component allows you to maintain the factory engine operating parameters. The most important advantages include:

• precise fit to the cylinder head socket and electrical harness,
• signal characteristics compliance with engine control unit requirements,
• reduced risk of recurring errors related to the eccentric shaft position,
• maintaining the correct dynamics and flexibility of the petrol unit.

By choosing an original BMW sensor, you gain a component designed specifically to work with a specific family of engines, which is particularly important in the case of advanced timing control systems.

Characteristics of the used component

The offered sensor comes from the group of used BMW parts, which allows you to reduce service costs while maintaining the original design. This type of component is often chosen when diagnosing engine performance problems, when it is necessary to replace a part with a proven OEM equivalent without investing in a new subassembly. A used sensor can be a good solution in situations where the price-to-functionality ratio and maintaining compliance with the factory installation are important.

Selection and application in service practice

When selecting an eccentric shaft sensor for a BMW 1 and 3 series with a petrol engine, it is worth paying attention to compatibility with the specific N46/N46N engine generation and body type (E46, E87, E90, E91). In workshop practice, this element is often replaced in the case of:

• errors related to the eccentric shaft position,
• uneven engine operation when cold or warm,
• power drops and limited throttle response,
• problems with starting the engine.

A properly selected and functional sensor allows you to restore the correct cooperation of the timing mechanics with the control electronics, which translates into more predictable car behavior in daily use.

If you are planning a comprehensive repair or upgrade of the engine area in your BMW and need other elements from the same group, such as position sensors, timing control elements, or fuel system components, check the available parts in the Other BMW category.

Substantive support and service cost optimization

When working with advanced power units, it is worth expanding your knowledge about the structural differences between individual versions of engines and drive systems. In this context, comparative material regarding sports units and their equipment may be helpful – you will find it in the article Audi RS vs other models – what is hidden under the hood and chassis?, which discusses, among other things, the specifics of engines, brakes, and chassis in more powerful variants.

If you want to better plan your repair budget and are considering using used OEM components, it is worth reading the guide on making informed choices about second-hand parts – you will find practical tips in the article Rising repair costs and the boom for used parts – how to save on car service?, which shows how to combine savings with care for the vehicle's technical efficiency.
