The BMW 335i E90/E92: A Mix of Issues and Revelations
The BMW 335i particularly from the E90/E92 generation produced from 2006 to 2013 is known for several common issues largely related to its N54 engine and the overall complexity of the vehicle. Here are some of the main problems owners reported:
Fuel Injector Failures
One of the most notable issues with the BMW 335i was the tendency for its fuel injectors to fail. These failures can result in rough running, misfires, and poor fuel economy. Many owners had to replace these injectors multiple times to maintain proper performance and efficiency.
HPFP (High-Pressure Fuel Pump) Failures
The high-pressure fuel pump (HPFP) was another common issue with the N54 engine. This component can fail, leading to a loss of power or the car not starting at all. The failure of the HPFP is notorious and can be a significant setback for owners.
Turbocharger Problems
Some 335i models equipped with the twin-turbo N54 engine faced turbocharger issues including wastegate rattle and turbo failure. These issues can severely impact the car's performance and reliability, making it a concern for many owners.
Electrical Issues
Owners reported various electrical problems, including issues with the battery, alternator, and various sensors. These can manifest as warning lights or other operational problems, adding to the car's list of common issues.
Cooling System Failures
The cooling system, including the water pump and thermostat, was prone to failures. These can lead to overheating if not addressed promptly, which can be damaging to the engine and other components over time.
Oil Leaks
The BMW 335i is also known for oil leaks, particularly from the valve cover gasket and oil filter housing. These leaks can not only be a maintenance hassle but can also indicate a more serious issue under the hood.
Maintenance Costs
BMWs in general are known for higher maintenance and repair costs, which can contribute to the perception of reliability issues. Regular maintenance and prompt attention to problems can help mitigate some of these costs.
While many owners have had positive experiences with their 335i, these common issues have led to a reputation for some reliability concerns. It's essential for owners to stay vigilant and address problems early to keep their cars running at their best.
A Visual Surprise: The Design
Chris Bangle’s designs are still a shock to the system. I still cringe whenever one of his "flame surfaced" 7 Series models appears. But the new 335i Coupe surprised me with its balanced proportions, elegantly cut creases, and conservative yet sporty design. Was Mr. Bangle on vacation when The Board of Directors approved this design? The exterior is a pleasant surprise. Inside, the 335i is workmanlike, with well-tailored leather that is about as sensually satisfying as a business class airline seat. One plus is the absence of iDrive, which allows for intuitive control of systems using clearly marked buttons on the dash. However, there is an unwelcome lack of attention to detail, such as window controls set far forward on the doors and a large blank plastic spacer where rear window switches should be.
Powertrain: The First Direct-Injected Twin-Turbo Inline Six
The 335i is distinguished by being the first direct-injected twin-turbo inline six produced by BMW. The 3.0-liter engine delivers 300 hp, sandwiched between the 330i sedan and the as-yet-unpriced and unavailable next-gen M3, which boasts 400 hp. This motor is a revelation, with lots of torque available from a standstill. There is little lag between low rev thrust and high rev insanity, making it exhilarating to drive. The engine is quiet and yet offers unrelenting urgency, with no hesitation in acceleration. The transmission, a six-speed automatic, is also a revelation, with smooth and precise shifts controlled by paddle shifters.
Dynamics and Handling
The 335i excels in dynamics and handling. While the brakes can be overly sensitive in stop-and-go traffic, they perform impeccably when the pace quickens. The steering is too firm at low speeds but just right in every other situation. With its manageable weight, carving corners in the 335i is seamless, and the car handles with a balance of luxury and performance. Despite the presence of run-flat tires, BMW has succeeded in delivering a car that is both plush and responsive to the road. The 335i drives with the comfortable ease of a gentleman’s M3, yet transitions to an intense, focused driving experience when needed.
Overall Impression and Conclusion
The 335i is a revelation, offering a unique driving experience that is both fast, comfortable, and economical. Its striking design and powerful, reliable engine make it a standout choice in the luxury sports car segment. For those who want a car that is more fun to drive than its $130,000 price point might suggest, the 335i is an excellent investment.
Conclusion: The BMW 335i Coupe is the best way to spend $40,000 to $50,000 on an automobile and still feel like you got a good deal. Its a killer app that simply dominates its competition, making it a top choice for any driver seeking a balance of luxury, performance, and practicality.
