Top BMW 335i Problems
Although the BMW 335i is one dependable luxury midsize car, it has its fair share of problems. Here are the most commonly reported issues for different model years:
Noise and Vibration Due to Low Refrigerant
According to some owners of the 2009 BMW 335i, problems with the A/C system are common for some units of this model year. Droning noises may be heard when the A/C system is operating, and the steering wheel may vibrate excessively. If these issues stop when the A/C system is turned off, the problem may be a low refrigerant charge in the system.
Some owners have reported hearing a “string in the fan” type of noise on the passenger side when they’re idling and feeling vibrations on the steering wheel. The vibrations reportedly stop when the A/C is turned off. Others experienced a steady vibration in the steering wheel for weeks. When they brought their vehicle to the dealer, they were told they needed a new A/C evaporator.
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.
Wastegate rattle or turbo rattle is the result of excessive movement between the wastegate and the wastegate seat. Other symptoms of this issue include rattling during cold starts, rattling during deceleration, loss of power, active check engine light, poor engine performance, and a registered OBD trouble code.
Broken Serpentine Belt
Faulty serpentine belts are among one of the most common 2008 BMW 335i problems. According to some owners, their serpentine belts broke and melted into their engines. This then caused their vehicle to break down in the middle of the road. Several drivers experienced even worse problems, with their car breaking down without prior warning. Some owners also had to deal with losing their power steering and then the car refusing to start again.
Faulty High-Pressure Fuel Pump
Many owners of the 2007 BMW 335i have complained about problems with its high-pressure fuel pump. The check engine light may also activate and the car may exhibit a lack of power.
According to several owners, their vehicles suddenly lost power and started longer than usual. Others noted that their car lost torque after they stepped on the gas. In some cases, the affected BMW 335is stuttered while ascending steep hills, and their transmission slipped when they’re going down steep inclines.
BMW has released a service bulletin to address this problem.
According to many owners of the 2007 BMW 335i, problems with its cooling system are common for some units of this model year. Some of them experienced high temperatures in the cabin of their vehicle despite the A/C system being active. Others complained about issues with their car’s water pump, thermostat, and fuel pump.
Engine issues are among the most reported 2007 BMW 335i problems. Engine overheating, poor gas mileage, running roughly, and turbo failure are typical for some units of this model year. According to some owners, when their car overheats, it automatically goes into limp mode. Others experienced rough idling accompanied by an activated check engine light.
