Walnut Blasting

Walnut Blasting

                                    Walnut blasting is now being offered at DJ Foreign Auto Care! What is walnut blasting you may ask? Walnut blasting is a process that is used to treat heavy carbon build-up. Cars require oxygen to run. With modern direct injection engines, when your foot is placed on the accelerator, the car releases gasoline into the combustion chamber of the vehicle. The spark plugs then ignite the gasoline in the combustion chamber, causing the car to run. Carbon is released into the engine as a byproduct of this process.  The carbon interferes with the vehicle’s normal combustion, which in turn alters the compression ratio, operating temperature, and sensor readings.  The carbon builds up and coats the inside of your engine including the air intake valves, combustion chamber, and exhaust, restricting your car’s ability to breathe and al ... read more

Cabin Air Filter

Cabin air filter replacement on a regular basis is important for keeping the air clean inside your car. The cabin air filter in your car functions like your home's furnace filter, filtering the air you breathe inside the car.

Engine Oil Flush Benefits

Engine Oil Flush Benefits

  "Engine oil flush" or "Performance Oil Change" describes a process where a service technician adds chemicals to the oil so that built-up carbon deposits are cleaned out of narrow oil passages, valves and combustion chambers.  The dirty oil and chemicals are then flushed out of the system and replaced with clean oil.  Performing an engine oil flush is especially beneficial when large amounts of sludge and deposits build up in the oil system, which can clog oil passages and potentially lead to serious engine problems, when the many moving parts in the engine get gummed up.  An engine oil flush can restore fuel efficiency and power to your engine, as well as save on wear and tear by keeping all the parts in your engine moving as they should.  A performance oil change / engine oil flush service may be a good idea when there have been long intervals between oil changes, when you purchase an older vehicle and you ... read more

Car Battery Replacement and Registration

Car Battery Replacement and Registration

Car battery replacement in newer European vehicles is more complicated than you might think!  Some customers may try to install their own battery without having a qualified shop program the battery to their car's computer. While initially the car may work and warning lights such as the "check engine" or "service engine soon" may not be triggered, attempting to do your own car battery replacement can cost you a lot more than you were bargaining for in the long run. The electrical systems in today's newer import vehicles such as BMW, Mercedes-Benz, Mini Cooper, Land Rover, Jaguar and other makes, are so sophisticated that they tailor the electrical charging to both the age and type of battery in the car.  There is a computer module inside the car that controls the alternator.  When you replace a battery, this computer needs to know that the car battery replacement has occurred, and also whether the battery is a traditio ... read more

BMW Water Damage

BMW Water Damage

  BMW water damage is a common problem that we see at DJ Foreign Auto Care. Water damage can occur when sunroof drains become clogged with debris, body seams between body panels lose their seal in locations such as the roof or trunk, door seals lose their seal, also water can splash up into the engine when the car is driven though a flooded area, especially at speeds above idle speed. Another problem that can contribute to BMW water damage is accidents. Some accidents result in the car's body and frame warping. If body work is performed, the body shop may shim parts to make them look right instead of straightening them (which may be impossible). This may leave a gap in the seals that is not visible, allowing BMW water damage to occur. Water leaks in cars can be very expensive to fix if the water leaks into the electrical system. This can result in short-circuits, damage to control modules and other damage that can be hard to find and repair. Many times the place where the wa ... read more

Headlight Maintenance

Headlight Maintenance

Headlight maintenance may not be the first thing that comes to mind of when you think of maintaining your car, but your car's lights are very important for your safety. Headlights and tail lights illuminate the road for the driver and make the vehicle visible to other drivers on the road. As well as being an important safety feature, keeping on top of your headlight maintenance can help you avoid getting pulled over and getting a ticket! Drivers should start to perform headlight maintenance by checking that all their lights are working, including low beams and high beams, and also by checking the lenses for fogginess or yellowing. Over time the plastic lenses can cloud over and become foggy, due to abrasive dirt and grime. Cloudy lenses should be replaced or a headlight restoration product can be used to clean, polish and restore the existing lenses. Headlights need to be checked regularly and aimed correctly by professional mechanics, to make sure the driver can safely see the ro ... read more

Replacing Your Engine - What To Expect

Replacing Your Engine - What To Expect

Tweet If you are replacing your engine, the process is not as simple as removing the old engine and dropping in a new one.  Replacing your engine can be a long and difficult process; since as well as being big and heavy, engines are made up of a lot of little parts.  Also an engine connects and works with several other systems including the electrical system, exhaust, transmission and cooling system. Since most people are not going to pay extremely high prices for a brand new or remanufactured-rebuilt engine, the general process for replacing your engine starts with your car repair shop finding a used engine that fits your car.  The "new" used engine should have a warranty on it, should be free from damage, should have good compression and relatively low mileage, if possible. Once the right engine is found, the old engine must be disconnected and removed from the vehicle and the ... read more

Car Suspension Problems - Warning Signs

Car Suspension Problems - Warning Signs

Tweet Driving with car suspension problems such as worn or leaking shocks/struts, loose or broken controls arms or other damaged suspension components can be just as risky as driving with bald tires or squealing brakes. But many drivers who have their tires and brakes inspected and replaced regularly don't think to have their suspension checked. If you experience any warning signs of car suspension problems such as: the car bouncing or swaying, the car does not handle well, the car does not sit level, or if the car is shaking or vibrating, you should have your vehicle inspected right away by a qualified professional. After a vehicle has 50,000 miles on the odometer, the suspension should be checked every time the brakes are inspected; at least once a year or every 12,000 miles. Some brands such as Land Rover/Range Rover and Mercedes-Benz include models that have air suspension. According to ... read more

BMW Crankcase Vent Valve Season

BMW Crankcase Vent Valve Season

  BMW crankcase vent valves fail more often this time of year and we see more of these types of problems as the weather gets colder. The BMW crankcase ventilation valve is also known as the oil separator, CCV, or PCV valve.  According to Wikipedia, "A crankcase ventilation system is a one way passage for gases to escape in a controlled manner from the crankcase of an internal combustion engine.  This is necessary because internal combustion inevitably involves a small but continual amount of blow-by, which occurs when some of the gases from the combustion leak past the piston rings (that is, blow by them) to end up inside the crankcase, causin ... read more
