The 2007 BMW 335i is a popular choice for enthusiasts seeking a blend of performance and luxury. However, like any vehicle, it has its share of common issues that potential and current owners should be aware of. Understanding these potential problems can help in making informed decisions about maintenance and ownership. This article delves into some frequently discussed issues associated with the 2007 BMW 335i, offering insights based on owner experiences.
One area often discussed is the turbocharger system. Interestingly, contrary to some assumptions, turbocharger failures are not widely reported as a primary problem for the 2007 335i. When considering maintenance costs, it’s worth noting that turbo replacements, if needed, can be in the region of $2,500.
Fuel injector issues are another topic that arises in discussions about the 335i. However, similar to the turbos, injector problems are not highlighted as a particularly prevalent issue specifically for the 2007 model. In fact, some reports suggest that the 328i and newer 335i models might experience injector problems more frequently. Replacing injectors can cost around $1,000, making preventative maintenance considerations important.
The High-Pressure Fuel Pump (HPFP) is a well-known component in the 335i, and BMW issued recalls related to this part. Many owners have had the HPFP replaced under warranty. It’s worth checking if the recall work has been done on any 2007 BMW 335i you are considering.
Carbon build-up on the intake valves is a more recognized issue for the 2007 BMW 335i, as it is common in direct injection engines. This is not unique to BMW and affects many manufacturers using direct injection technology. Owners report needing intake valve cleaning, sometimes around the 60,000-mile mark.
Moving to general E90 platform issues, the Oil Filter Housing Gasket (OFHG) is a common point of maintenance. Many owners have addressed this themselves, often around the 58,000-mile mark. The Valve Cover Gasket, however, is reported to be less problematic for this model year.
Preventative maintenance on components like the water pump and thermostat is advisable based on age and mileage. Replacements are often recommended around the 60,000-mile mark or based on vehicle age, with parts costing approximately $440. Similarly, belt tensioners are often proactively replaced around 100,000 miles.
Finally, some owners have encountered issues with the DSC system. The Bosch DC electric motor within the DSC module can experience problems due to graphite debris, affecting the brushes. Repair services are available, offering cost-effective alternatives to full unit replacement.
In conclusion, while the 2007 BMW 335i has potential maintenance items to consider, many are common for vehicles of this type and age. Focusing on a well-maintained example, rather than solely seeking out low mileage cars, might be a more practical approach. Cars that have had these common issues addressed proactively might offer a more reliable ownership experience in the long run.
