How often should I change oil on my 330Ci?
Changing oil every 15,000 miles is what BMW recommends. However, the right oil change interval actually depends on your fuel consumption and the kind of oil you are using. You can go past 3,000 to 7,000 miles, depending on what suits your car.
How do I reset my service indicator?
It is very simple—you just have to push and hold down the trip meter button and then switch the ignition key to accessory position. When "reset" appears, release the button and then press it right away and hold it again for around five seconds. When "reset" flashes, release the button and press it again.
Is there a surefire way to make the battery perform better and last longer? I do not want to buy another expensive OEM battery when this one in my BMW 330Ci wears out.
Cleaning your battery can boost its performance without putting a dent on your wallet. Doing so eliminates corrosion that keeps your 330Ci from recharging the battery while you are driving it. Regularly check your battery for any signs of corrosion or accumulation of crusty green or white dirt. When cleaning your battery, be extremely careful and always wear gloves and safety glasses to protect you from its flammable and poisonous fluids.
Lately, it would take longer for my 330Ci to start. I am afraid it would not start at all. Why does it happen?
It could be a case of a battery that is about to die. Have you checked yours recently? On the average, batteries last for up to six years. An obvious symptom of battery failure is that it gets colder, and your car hesitates before it starts. In that case (and if your battery has hit its age limit), you should consider replacing your dying battery. Fortunately, battery replacement is a task so simple that you can do in your garage. This DIY job takes only minutes to complete. If you need a new battery fast and cheap, then an aftermarket battery is a great choice—it can save you as much as a hundred dollars. As soon as you get a hold of a new battery, you will only need to get your tools ready (a socket set and screwdrivers) and then you can start your DIY battery replacement. When you are done, make sure to reset your clock, which will reset your odometer as well. Then start your car. If it doesn't, then check the alternator—it might also need to be replaced.
Is bleeding brakes something I should trust to the mechanic? Can I do it on my own instead?
Especially if you are budget-conscious, it is best to bleed the brakes by yourself. This DIY job is quite easy with simple tools such as a brake bleeding kit, 9-mm. wrench, rubber mallet, and turkey baster that will help you remove excess brake fluid if you are going to change it out. You will also need someone to help you lift your 330Ci off the ground before you bleed the brakes. Of course, you also have to get your fresh brake fluid ready. Check the brake fluid bottle—it should not have been opened because the fluid easily absorbs moisture, which lowers its boiling point. This vital car maintenance task must be done at least every two years for your own safety on the road and so that you can drive your 330Ci for many more miles.
