2009 Porsche Boxster (987) problems

Common 2009 Porsche Boxster (987) problems

The Porsche Boxster (987) 2009 is known for several common problems, primarily related to the intermediate shaft (IMS) bearing and rear main seal (RMS) issues.

• RMS Oil Leak: The RMS is another common problem area in the Porsche Boxster 987. The RMS is responsible for sealing the transmission's rear end, preventing oil leaks. A leaking RMS can cause significant damage to the clutch in manual cars if not addressed promptly. While this issue is more prevalent in cars with higher mileage, it can also occur in lower-mileage vehicles. Some caution is required when purchasing a used Boxster 987, particularly if the vehicle has been stored for extended periods.

• Suspension Problems: Suspension issues are the second most common reason for a Boxster 987 to fail its MOT. Broken coil springs are a common culprit. During a test drive, listen for clicking sounds and humming from the rear of the car, which could indicate suspension problems. A good Porsche specialist can repair most suspension issues, but it is essential to ensure that the cost of imminent work is reflected in the price paid for the car.

• Engine Management and Emissions Control: The Boxster's engine management system and emissions control can cause issues, particularly in older models. A common cause of the check engine light is a failure in the O2 sensor and mass airflow system. The mass airflow sensor may begin to fail, delivering inaccurate information to the engine management system. This can lead to adjustments in fuel mixtures, causing the front O2 sensors to report faults and often fail completely. Replacing both the mass airflow sensor and front O2 sensors simultaneously is recommended.

• Ignition Coils: Ignition coils on the M96 and M97 Boxster engines have been updated by Porsche multiple times due to cracking issues. Low-mileage older cars commonly still have the older style coils, and it is best practice to replace them all with the newer versions, even if only one coil has failed. This is particularly important in cars with high mileage.

• Brakes: While the brakes on the Boxster 987 are excellent, they may not feel as heavily servo-assisted as those in most cars. It is essential to check the life left in the discs and pads before deciding how much to offer for the car. If discs have a rough surface, circular grooves, or a pronounced outer lip, they will need replacing in the near future.

• Coolant Radiators and Air Conditioning Condensers: The Boxster 987's design means that the vents at the front of the car can become blocked by biomass, leading to potential issues with the coolant radiators and air conditioning condensers. Regular maintenance and cleaning are essential to prevent these problems.

While these common problems can be concerning, it is important to note that the Porsche Boxster 987 is generally a reliable vehicle, with an MOT pass rate ranging from 82.3% for 2005 models to 91% for more recent models. When purchasing a used Boxster 987, it is crucial to have the vehicle inspected by a reliable Porsche specialist, who can identify any potential issues and provide guidance on the cost of repairs.
