BMW 330i Problems – 1. faulty ignition coils
When you’ve driven a BMW for many years, you probably have noticed some problems, like rough idling. While it may be tempting to ignore the problem, you should consider having the ignition coil replaced before the car suffers further damage. The next time you see these symptoms, make sure to have the car checked by a certified mechanic. They will be able to diagnose the problem quickly and recommend the appropriate course of action.
BMW 330i Problems – 2. faulty oil filter housing gasket
A faulty oil filter housing gasket can cause a number of problems with your BMW. If the gasket becomes corroded or damaged, you can expect your car to overheat and suffer from poor combustion. If you want to prevent this from happening, you should replace the gasket. Replacing the oil filter housing gasket is a relatively straightforward two-part process. First, remove the oil filter housing from the engine. Next, unscrew the two bolts holding the housing to the engine.
BMW 330i Problems – 3. faulty heater core
If you’ve noticed that your car is running warmer on one side than the other, you may have a faulty heater core. While BMW vehicles are known for their performance, sensuality, and comfort, they’re not immune to mechanical maladies. Faulty heater cores can make your drive very uncomfortable and even dangerous. If you suspect that your heater core is the culprit, here are a few things to look for.
BMW 330i Problems – 4. faulty crankcase bearing bushing
If you’ve ever replaced the crankcase bearing bushing in a BMW, you’ll know how confusing these parts can be. While the letters and numbers may be easy to understand, there’s a bit of confusion with the various types of bearings. There’s thrust bearings and main bearings and even more color choices! BMW has a unique approach for this part: instead of using only one color, you can select any one you want.
BMW 330i Problems – 5. faulty automatic headlights
If your BMW 330i has automatic headlights, the problem could be in the stepper motor or in the low beam projector. The stepper motor is located inside the headlight housing, under the cover of the headlight housing. The link between the stepper motor and the low beam projector can fail. There are repair kits for the stepper motor on the internet. However, you must first remove the headlight. To access the stepper motor, open the access door behind the headlight and remove the cover. The seal may be not properly seated. Water will enter the headlight and damage the adaptive module.
BMW 330i Problems – 6. faulty brakes
A faulty set of BMW brakes can cause the car to squeal and jerk when it pulls away from a stop. BMW’s technical service bulletin for this problem cites the same issue. When the problem reoccurs four months after the dealer replaced the valve, it’s time to visit a BMW field engineer for a repair. After evaluating the car’s faulty brakes, the BMW field engineer determined that the problem was related to the vacuum pump.
BMW 330i Problems – 7. faulty steering
The active steering fault light in a BMW 330i may come on after a wheel alignment or if the steering wheel has been bent. A faulty active steering rack, DSC module, yaw sensor, or steering angle sensor can cause this fault. Make sure the power steering fluid level is at the recommended level. Most BMWs use CHF 11S hydraulic fluid. If these things are not the cause of the fault, then you should contact the manufacturer and have the steering wheel replaced.
