5 Top 2008 BMW 328i Camshaft Position Sensor Reviews & Buying Guide
Anyone who’s owned a BMW knows they’re fantastic machines, but sometimes even the best cars need a little TLC. If you’re driving a 2008 BMW 328i and experiencing engine hiccups like rough idling, stalling, or a pesky Check Engine Light, a faulty camshaft position sensor could be the culprit. This small but mighty component plays a crucial role in your engine’s timing, so a bad one can really throw things off.
Replacing your 2008 BMW 328i camshaft position sensor doesn’t have to be a headache. We’ve done the legwork to help you find a reliable replacement. Let’s dive into our top picks that offer great performance and value, ensuring your BMW runs smoothly again!
Why is the Camshaft Position Sensor So Important?
Think of your engine as a finely tuned orchestra. The camshaft position sensor is like the conductor, telling the Engine Control Unit (ECU) exactly where the camshaft is rotating. This information is vital for the ECU to accurately time the spark plugs and fuel injectors, ensuring efficient combustion and optimal engine performance. When this sensor goes bad, your engine’s timing can get out of whack, leading to a range of frustrating issues.
Common Signs of a Failing Camshaft Position Sensor
How do you know if your 2008 BMW 328i camshaft position sensor is failing? Here are some tell-tale signs to look out for:
- Illuminated Check Engine Light (CEL): This is often the first indicator. Diagnostic codes related to camshaft position (e.g., P0340, P0341) will usually appear.
- Hard Starting or No-Start Condition: The engine might crank but struggle to fire up, or not start at all, especially when warm.
- Engine Misfires or Rough Idling: You might feel the engine shaking or running unevenly, particularly at idle.
- Decreased Fuel Economy: Improper timing can lead to less efficient fuel consumption.
- Stalling: Your engine might randomly cut out while driving or at a stop.
- Reduced Engine Power or Hesitation: You might notice a lack of acceleration or the car feeling sluggish.
If you’re experiencing any of these symptoms, it’s a good idea to get your BMW checked, and the camshaft position sensor is definitely a prime suspect.

Important Considerations When Buying a Camshaft Position Sensor
Choosing the right 2008 BMW 328i camshaft position sensor can make all the difference. Here’s what to keep in mind:
- Compatibility: This is paramount. Always double-check the product’s fitment list against your specific BMW model, year, and engine type (e.g., N52 for your 328i). Comparing the OEM part number on your old sensor to the new one’s listed numbers is the best way to ensure a perfect match.
- Quality & Brand Reputation: While OEM is always a safe bet, many aftermarket brands offer excellent quality at a fraction of the cost. Look for brands with good reviews and a track record of reliable parts.
- Warranty: A good warranty (e.g., 1 year or more) provides peace of mind in case of a defective part.
- Single vs. Set: Decide if you need one or both sensors. Your N52 engine typically has two camshaft position sensors (intake and exhaust). Sometimes, when one goes bad, the other might not be far behind. Replacing both can be a proactive measure.
- Ease of Installation: Most modern camshaft position sensors are designed for direct, plug-and-play replacement, making them a popular DIY task.
Installation Tips
Replacing a camshaft position sensor on a 2008 BMW 328i is generally a straightforward process for the average DIY mechanic. You’ll typically need basic hand tools.

FAQ Section
Q1: What exactly does a camshaft position sensor do in my 2008 BMW 328i?
A1: The camshaft position sensor (CPS) monitors the rotational position of your engine’s camshaft(s). It sends this data to the Engine Control Unit (ECU), which uses it to determine the precise timing for fuel injection and spark plug firing. This ensures your engine runs efficiently and powerfully.
Q2: What are the most common symptoms of a failing camshaft position sensor in a BMW 328i?
A2: Common symptoms include the illumination of the Check Engine Light (often with codes like P0340 or P0341), difficulty starting (especially when the engine is warm), engine misfires, rough idling, stalling, reduced fuel economy, and a general loss of engine power or acceleration.
Q3: Can I replace the camshaft position sensor on my 2008 BMW 328i myself?
A3: Yes, for many DIY enthusiasts, replacing the camshaft position sensor is a manageable task. It typically involves disconnecting the battery, locating the sensor (usually on the cylinder head), unplugging the electrical connector, unbolting the old sensor, and installing the new one. Always consult a repair manual or reliable online tutorial specific to your N52 engine.
Q4: How many camshaft position sensors does a 2008 BMW 328i (N52 engine) have?
A4: Your 2008 BMW 328i with the N52 engine typically has two camshaft position sensors: one for the intake camshaft and one for the exhaust camshaft. Both are critical for the engine’s Valvetronic system and optimal performance.
Q5: Is it better to buy an OEM camshaft position sensor or an aftermarket one?
A5: OEM (Original Equipment Manufacturer) sensors are guaranteed to fit and perform exactly like the factory part, but they can be more expensive. High-quality aftermarket sensors can offer comparable performance and reliability at a lower cost. Look for reputable aftermarket brands with good reviews and warranties.
Q6: Will a bad camshaft position sensor damage my engine?
A6: While a faulty camshaft position sensor typically won’t cause immediate, catastrophic engine damage, it can lead to poor engine performance, increased fuel consumption, and in some cases, difficulty starting or stalling, which can be inconvenient and potentially leave you stranded. It’s always best to address the issue promptly.
Q7: After replacing the sensor, do I need to clear the Check Engine Light?
A7: Yes, after replacing the faulty sensor, you’ll need to clear the Diagnostic Trouble Codes (DTCs) using an OBD-II scanner. In some cases, the light might turn off on its own after several drive cycles if the issue is resolved, but clearing it manually confirms the fix and allows you to monitor for any new codes.
