The 2007 Bmw 335i Coupe 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. This article delves into some typical problems experienced with the 2007 BMW 335i Coupe, aiming to provide a balanced perspective on its reliability.
One notable point is the misconception surrounding turbocharger issues in this model. Contrary to popular belief, significant turbo problems are not universally prevalent in the 2007 335i. While turbocharger replacements can be costly, this isn’t necessarily a guaranteed expense for all owners. Similarly, fuel injector problems, often cited as a concern, are not exclusive to or overwhelmingly common in the 2007 335i Coupe. In fact, some suggest that other BMW models, including later 335i versions and even the 328i, might experience injector issues more frequently.
A known recall for the high-pressure fuel pump (HPFP) affected all 335i models of this era. Many owners had the HPFP replaced under warranty, and reports suggest that both the original and replacement pumps haven’t presented widespread issues, with some expecting a lifespan of 10 years or 120,000 miles from BMW’s replacement.
Intake valve carbon buildup is a more recognized issue, inherent to direct injection engines like the one in the 335i. This is not unique to BMW; many manufacturers using direct injection technology face this problem. Carbon buildup on the intake valves is a maintenance item that owners should anticipate, typically requiring cleaning services around the 60,000-mile mark, as indicated by experiences with valve cleaning at 61,000 miles.
Concerning general E90 chassis issues, the oil filter housing gasket (OFHG) is a known weak point. Many DIY mechanics find themselves replacing this gasket around the 60,000-mile mark to prevent oil leaks. On the other hand, valve cover gasket issues appear to be less frequent in the 2007 335i Coupe.
Preventative maintenance, rather than reactive repair, seems to be a sensible approach with components like the water pump and thermostat. Despite not experiencing failures, some owners opt for preemptive replacement around the 60,000-mile range, citing mileage and age as factors. Similarly, belt tensioners are often considered for replacement around 100,000 miles as a preventative measure.
Another reported issue, sometimes mislabeled as DSC system failure, often traces back to the Bosch DC electric motor within the DSC module. Graphite debris accumulation can cause brush sticking in this motor. While complete DSC unit replacements might seem necessary, companies specializing in module repairs offer more cost-effective solutions, and some resourceful owners have even managed DIY rebuilds.
In conclusion, while the 2007 BMW 335i Coupe has potential maintenance points like any vehicle, many commonly cited “problems” are either overblown or manageable with proactive maintenance. Focusing on a well-maintained example, potentially one where some of these typical issues have already been addressed, might be a more prudent approach than solely seeking out a low-mileage, garage-kept car. Mileage or age alone doesn’t dictate reliability as much as consistent care and addressing known maintenance items.
