BMW 335i Problems
The Check Engine Light may illuminate and/or a lack of power may be noted due to a failed high pressure fuel pump. BMW has released a service bulletin regarding this matter, the suggested repair is to replace the failed high pressure pump.
A droning type noise may be noted when the air conditioning system is operating. Additionally, a vibration may be felt in the steering wheel. If these issues are no longer present when the AC system is turned off, the problem may be low refrigerant charge in the system. Our technicians remind us that if the refrigerant charge is found to be low, proper leak diagnoses should be performed in addition to recharging the AC system.
Noticed when having difficulty starting the car, took it to dealer, they said it was the fuel pump.

The fuel pump may fail due to improper nickel plating during manufacturing. This can cause the engine to stall while driving. The dealership will replace the fuel pump free of charge to correct the problem.
The front passenger seat contains a mat that determines the presence and size of a seat occupant. This input to the airbag controller helps to determine if and how forcefully the passenger airbag should deploy in the event of a crash. The detection mat can develop cracks and fail. If this were to occur, the airbag would not deploy as expected, increasing the risk of personal injury. Dealers will repair the occupant detection mat to eliminate the possibility it may crack. Additionally certain vehicles will receive and extended warranty on the front passenger seat occupant detection mat.
The vehicle battery is connected to the fuse box via a heavy duty cable. It has been determined that the cable connection at the fuse box can degrade over time, resulting in increased electrical resistance. This increased resistance can cause the connection point to overheat and break, resulting in a loss of electrical power and causing the engine to stall, increasing the risk of a crash. Dealers will replace the positive battery cable connector and secure it with an improved method to correct this concern.

Grow up and enjoy the ride.
Very fun car to drive. However early on I had to replace 2 fuel pumps on BMW's dime(BMW has since taken care of this issue). Another issue I have is with the sport trim which is aluminum. It scratches and dings very easily. I have not had any other problems and the car still makes me smile every time I drive it after 4 years. As far as the drive goes I would say it is what you'd expect from a...

Replaced rear tires at 13,000 and had alignment done. Next day a friend told me my wheels looked like they were leaning in at the top, I thought he was joking but I told him it's fine I just had it aligned for $180 and 2 new tires at $1,000! Guess wh...
