What are common 2008 BMW 335i problems?
Many owners of the 2008 bmw 335i have complained about problems like the engine rattling and the check engine light turning on. Their car’s turbo engine developed wastegate issues that became worse over time, more so in harsh driving conditions. The 335i had a slight increase in problems in 2013 and 2014, though the issues were still rarer and usually less serious than the 2007, 2008, and 2009 model year releases.
What gen is a 2008 335i?
The BMW 3-series is without question one of our favorite cars, reigning on our yearly 10Best Cars list for the past 16 years. The current and much-praised, fifth-generation E90 version is no doubt the best, and is among the most rewarding cars to drive at any price. The B58 proved that BMW had learned from the N54/N55 era. It’s smoother, stronger, and more dependable while still capable of delivering 600–700+ wheel horsepower with the right upgrades.While the N55 engine is known for its improved reliability compared to the N54, it still has some potential issues, including the electric water pump, VANOS solenoids, and oil leaks from the valve cover gasket and oil filter housing.Oil leaks plagued the N54 as well as other naturally aspirated inline-six BMW engines from the that era. The valve cover gaskets, oil filter housing gaskets, and oil pan gaskets were the most prone to leaking oil. Oil leaks are bad news, but on N54 engines they are especially concerning.Is BMW’s N54 engine the best they’ve ever made? The N54 is one of the most popular engines from the German manufacturer — not necessarily because it’s the highest-revving, the most powerful, or the most reliable — but because of its power potential, versatility, and tunability in the hands of the aftermarket.Like its predecessor, the N55 is a turbocharged 3. L inline-6 cylinder engine known for its tremendous horsepower and fuel efficiency. Unlike the N54, the N55 uses a single twin-scroll turbocharger as opposed to the twin-turbo layout, allowing it to produce more power over a broader range.
Is the 335i a 6 cylinder?
The 335i is one of two 3-series coupes. The other is the 328i. It has a smooth 3. Owns this car My 335i Has been surprisingly reliable. In the 140k miles I’ve owned mine, ive only had to replace the water pump and surrounding hoses, and the battery. Rating breakdown (out of 5): Comfort 5.
How to know if a BMW is N54 or N55?
The main differences between the N55 and its N54 predecessor are the use of a single turbocharger, the addition of Valvetronic and the type of fuel injectors. Whilst the N54 used a twin-turbo arrangement, the newer N55 uses only a single twin scroll turbocharger. In simple terms: An N55 magnet is about 5–6% stronger than an N52 of the same size and shape. When Should You Choose N55 Over N52? N55 magnets are ideal when you need maximum force in the smallest space, or when every ounce of magnetic strength matters.Grades indicate maximum energy product (MGOe). Higher = stronger. N52 vs N55: N55 offers more force in the same size but costs more and may demagnetize easier under heat/stress. Choose N52 for most uses; upgrade to N55 for space-critical applications.What is the main difference between the B47 and N47 engines? The main difference is that the B47 is a newer, more advanced engine with improved fuel efficiency, less turbo lag, and fewer common issues, especially in terms of timing chain failures compared to the N47.The N54 provides better performance potential and stronger internals but at the cost of increased complexity and reliability issues. The N55, while more reliable and simpler in design, offers nearly comparable performance to the N54, while remaining easier to maintain.
