BMW tune-ups and maintenance can lengthen the life of your prized BMW. Here at Shaus Motorsport in Aurora, we think maintenance and tune-ups are an excellent way to improve the performance of your vehicle and reduce your chances of major issues. Though “tune-ups” aren’t really used the same way as they did in the past, you can certainly tune-up your engine by taking care of the following areas of your BMW machine.
A spark plug can tell you a lot about the condition of your BMW’s condition. Inspecting your spark plugs during regular BMW tune-ups and maintenance can reveal early possible problems. We recommend getting them checked every 30,000 miles and replaced every 100,000 miles. Changing your spark plugs avoids them seizing in the block which can result in expensive repairs in the future. Be sure to track which cylinder the spark plug came out of so that you are aware of which cylinder may have a problem.
Spark Plug Wire Sets
Spark plug wire sets used to need to be replaced with regularity. There have been dramatic reductions in failures and problems due to the use of better materials and sizing. They also now have increased operating ranges. These wires should be tested for proper resistance but they no longer warrant routine replacement like other parts of your BMW.
Distributor Cap and Rotor
The rotor and the distributor cap are generally plastic and so they often deteriorate with use over time. Cracks can develop which can let in moisture. Both the distributor cap and rotor have metal contacts that can corrode. If the contacts become worn, your BMW engine can misfire as a result. Be sure to have these parts replaced when they are worn or at least checked for issues during BMW tune-ups and maintenance.
Air filters trap dirt and other particles as the air passes through the filter. In older BMWs, the air filter helps to protect the carburetor. In newer models, the air filter is helping to protect the fuel injector. Generally, you should replace your BMW air filters every 20,000 miles. If you live in a dusty area or drive dirt roads, your vehicle’s air filter will need to be replaced more frequently. Any air filter that looks really dirty or is damaged should be replaced regardless of how many miles it should last.
One of the basics of BMW tune-ups and maintenance is your oil filter which is simple to replace and doing do stops unnecessary wear on your engine. Oil filters remove rust, soot, and any other solid contaminants from your engine’s oil. They should be replaced every 3,000 miles at the same time that your engine’s oil is replaced.
PVC Breather Filter
Every 30,000 miles your PVC filter should be changed. Your PVC filter makes sure that only clean air is drawn through the PVC breather. If your PVC filter is clogged, your PVC is unable to siphon away the moisture and gases created by engine combustion. A clogged PVC filter will cause sludge buildup and can result in oil breaking down.
A BMW fuel filter stops various contaminants from getting into your fuel system. These contaminants can clog the injector inlet screens. The pintle valve and seat can also get clogged if dirt and contaminants get into the injector itself. In older cars, the fuel filter helps stop dirt from plugging up the carburetor’s fuel metering openings.
Clogged fuel filters can result in your vehicle stalling due to a restriction of fuel flow. They can also cause loss of speed power as well as hard starting. To avoid these problems, change your fuel filters every 30,000 miles, annually, or when other fuel system parts need to be replaced as well (whichever of these conditions happen to occur first).
Automatic Transmission Filter
Transmission filters help the transmission fluid stay clean enough to properly transmit energy as well as cool and lubricate the moving parts of your BMW transmission. If your transmission filter is clogged, your transmission may slip, have trouble engaging gears, and hesitate. To help your engine last longer, your transmission filter should be changed around every 12,000-15,000 miles during regular BMW tune-ups and maintenance.
Easiest Way to Extend Engine Life
If there is one thing that can easily and inexpensively help your engine last longer, it is changing your filters. If you need your BMW’s filters changed, contact us at Shaus Motorsport in Aurora.
Other BMW Maintenance Parts
There are other parts that are not technically BMW tune-ups and maintenance areas but they can help the “tune-up” work be more successful. Some of these may be viewed as not critical but that’s not really true. If your vehicle needs to pass emission tests, taking care of the parts are essential to keeping your BMW working properly and operating safely.
- Oxygen sensor: Also called your O2 sensor, this engine part should be replaced at recommended intervals. A worn down oxygen sensor can change your engine’s settings in a negative way.
- Vacuum hoses: Each vacuum hose needs to be checked and replaced as may be necessary. A number of your vehicle’s major systems rely on the manifold vacuum’s signals and functions. Even the smallest leak in your vacuum hoses can cause serious performance issues. In some cases, your BMW may not run with a vacuum leak and checking them can help keep you on the road.
- Temperature sensors: The sensors in your vehicle control your cooling system, the exhaust system, and the fuel injection system. If one of your temperature sensors is not functioning properly, your BMW will likely not perform well either.
Other Tips for Your BMW
Cleaning your engine is preventative maintenance. If your engine is clean, it runs better and cooler. Clean engines also last longer. So, make sure that you’re taking care of your vehicle’s needs on a regular basis.
Keeping up with your BMW tune-ups and maintenance will keep your BMW humming and will help your engine last much longer. Contact us here at Shaus Motorsport in Aurora if you need some maintenance performed on your BMW.
