BMW 330i Problems
A member of BMW's illustrious 3 Series, the BMW 330i is one of the most remarkable models to come out of the line. While it didn't debut during the series' earlier generations, the 330i has already had several versions throughout the years. Each version of course improved from previous installments. However, with each new version also came new difficulties. Below are some of the most common problems encountered when driving a 330i.
Several suspension components of the E46 BMW 330i (which was released in 1999) were reported to be weak. The said parts, which included rear coil springs and ball joints, usually wouldn't last that long before they would break. There were also a few reports of the rear suspension mount surprisingly breaking through the car floor, as well as faulty front control arms and rotors that caused vibrations.
The E46 BMW 330i came with a then-new M54 engine. While the said engine was generally both heavy-duty and reliable, there were still problems that arose (mostly limited to models with manual gearboxes and those that have the unique high-performance ZHP package). This included reports of the M54 engine's ECUs (electronic control units) being plagued by rough idles, power delivery issues, and flat spotting. Because of those, the M54's ECUs needed to be overhauled.
Although BMW fixed those issues in the next generation (E90) of the 330i, there were still some reports of automatic gearboxes that experience difficulty in shifting.
Steering also became an issue for some E46 BMW 330is as there were several reports of owners experiencing heavy steering. BMW addressed this problem by retrofitting the 330is of the complaining owners with new steering racks. With the improved steering capabilities of the then-problematic 330is, the issue was eventually put to rest.
Although this is a minor issue, the E46 BMW 330i's sunroof problems bugged some owners. For instance, the sunroof often got stuck. Owners were advised to regularly grease the sunroof tracks to prevent that from happening. Another complaint regarding the sunroof was that it tended to forget its initialization for various positions. BMW released instructions on how to fix it though.
Three Important Tire Maintenance and Service Tips for Your BMW 330i
Most car enthusiasts and drivers hold the BMW in the highest regard—these are good cars equipped with speed, agility, and precision steering. It won't be surprising, though, that you would choose to drive a BMW 330i. Besides, the 330i belong to the series that's considered as BMW's best-selling model and have won numerous awards throughout the years.
You'd surely want to be able to drive your car for a long time and also avoid headache-causing blunders caused by car problems. Among the major components of your car that you might want to focus your attention to are the tires. They don't only affect the performance and handling of your vehicle but also its safety. Below are three major maintenance and service tips to help you maximize the life of your tires as well as keep them up to the safety standards:
- Make sure your tires have the recommended tire pressure.
Incorrect tire pressure is the number one cause of premature tire wear; or worse, blowouts. Properly inflated tires prolong the life of your tires and improve your car's fuel efficiency. If you want better handling and comfortable ride with dependable traction, you should make sure that your tires are properly inflated. In the sidewall of your tires, you will see amount of PSI needed for your tires. Now, the maximum inflation or PSI number does not always necessarily mean that it's the optimum PSI for your vehicle. Recommended tire pressure is usually between 30 - 35 PSI depending on the maximum load-carrying capacity of your vehicle.
- Understand the importance of tire rotation.
If you want to prolong the life of your tires, you need to rotate them on a regular basis. This helps your tires maintain an even amount of treadwear. Uniform wear on your tires reduces wheel vibration and other issues that could compromise safe driving. Rotating your tire is so important that some manufacturers even include periodic tire rotation as a stipulation of their warranty. Aside from safety and longer life benefits, tire rotation can also improve gas mileage, protect suspension components, and give you smoother ride. Also, remember that the front and rear tires wear differently—with the front tires taking more brunts from steering and resistance during parallel parking. You can have a mechanic rotate the tires for you or you can do it yourself. Just make sure to inspect the treads first when you unmount your tires before mounting them again. The tread patterns on the tires will tell you whether you need replacement soon.
- Make sure your vehicle has proper tire alignment.
When you unmount those tires and check the treads, notice if there's uneven tread wear. This could be a sign that your tires are not properly aligned. Tire or wheel alignment refers to the adjustment of your car's suspension—the one that connects the vehicle to the wheels. When out-of-alignment, the suspension and steering system of your vehicle will no longer function at the right angle. Wheel alignment has several benefits including increased fuel efficiency and improved handling. When you notice that your BMW 330i is pulling to the left or right and the steering wheel is off center and vibrating, it's time to take it to the service center for a much-needed wheel alignment.
