All Major and Minor Repair Work on German Car Lines

Engine | Transmission | Chassis | Body | Electrical | Electronics



Unlike many foreign car repair shops which service American, Asian and European cars, we do not service Japanese, Korean, British, French, Italian or American cars. We service only German cars which include Mercedes, BMW, Porsche, Audi, Mini, and VW. We have found that the ability to specialize makes us more efficient, and more cost-effective for you. With just six car lines, we have the ability to keep up with the latest technology and purchase all the specialty tools needed to perform any job. As tools are quite expensive, we would not be able to do this if we worked on too many different car lines, and would have to jeopardize the job, sublet the work to other shops, or perform only selected work. At Haik’s we perform all mechanical and electronic work your car may need. You might call us a "One-Stop Shop for German cars."

Today’s cars are complex machines. More akin to spacecraft than terrestrial vehicles, they are very demanding of the auto technician. High level skills and specific expertise are required in diagnosing, repairing and maintaining the car of today. Expert craftsmanship and knowledge of mechanical and electronic systems is mandatory. Auto mechanics must be versed in electronic computer control systems as much as mechanical systems. At Haik’s, our technicians maintain this skill level at its peak.


Up-to-date technical information is essential in properly testing electronic devices. The specifications of these electronic devices, such as sensors and actuators, are needed to accurately measure electrical signals to and from each unit. Only through proper measurement can we determine whether a unit is doing its job or causing problems. Obtaining this information is also quite costly. Auto repair shops purchase the information in book form or online from companies which gather the information from the car manufacturers. They pay dearly for the information and in turn charge us dearly for packaging the information and delivering it to us. This is today’s system of auto repair. Over thirty-five years ago, when I started my shop, things were quite different. Electronic fuel injection was just beginning. Now, everything is electronically controlled.


The automobile is not merely a conglomeration of miscellaneous parts. It is composed of sophisticated systems. Mechanical systems which have been refined and enhanced throughout the years of automotive history, now use electronic controls (computers and sensors) to guide them. Each system has its own control unit (computer). Hardly any feature of today’s car is without its own electronic management control, from fuel and ignition management of the engine to transmission shifting, braking, steering, seat belts and air bags, air conditioning and heating, window operation, lighting and even suspension on some exclusive models. The result is greater safety, comfort and efficiency..

Along with this sophisticated technology comes complexity of repair. As with any device, problems arise and breakdowns occur. When a failure occurs in today’s cars, repair is not a simple task. Just figuring what went wrong can be a major problem. This is aside from the actual repair. There are so many components in each system. The failure of any one of these components could cause the entire system to go down. When something goes wrong, the first step is to determine the source of the failure. Proper diagnosis is essential. Every component is suspect. In some cases, tracing down the culprit can take hours, sometimes longer than the repair itself. Unlike mechanical objects, electricity cannot be seen. Each electronic component in the system must therefore be tested for proper function. (The electronic control units themselves cannot be tested. They are far too complicated.)

TTo assist with the diagnostic process, onboard computer diagnostics is standard on every car today. When a problem occurs, the control unit monitoring its specific system, sets one or more codes. Theses “diagnostic trouble codes” (DTCs) warn of a failure in the system. In some cases it will set a “check engine” light or a “service engine soon” light if the problem is related to emissions (engine, transmission or one of the smog systems such as secondary air-injection or the evaporation system). The braking system has its own warning light “ABS” (anti-lock braking system). Air bags and seat belts have their own warning light “SRS” (supplemental restraint system). Whether a warning light is lit or not, there can be DTCs stored in the system. It is always advisable to interrogate the engine management system during a mid-level or major service.

When a problem occurs, mechanics read the trouble codes using a special shop computer called a scanner or scan tool. Reading the codes is merely the first step in determining the course of action. The codes does not usually give the answer to the problem. They reveal an abnormality in one of the circuits leading to or coming from the control unit (input or output). The code may reveal which component is involved, but replacing the component without further testing is a big mistake. The component mentioned by the code may not be the source of the problem. The component may not be getting power, or it could have a bad ground, or a wire leading to it or coming from it may be damaged. It is also possible that the control unit itself is burned out on that circuit. Caution is always primary. The work of diagnosis and further testing should always be done before the replacement of components or any repairs. For this purpose, a good scanner is invaluable in testing most components and system functions. It is important that the customer be aware that diagnosis is an essential part of the repair, and therefore will have a charge. The mechanic must use his time and equipment. The price of a good scanner is expensive. Our scanner, together with three programs, costs over $30,000. Cheaper scanners perform fewer functions, and considering the scanner is one of the most important tools in the shop, we have purchased the best. Expenses with the scanner do not end with the purchase. Repairs and annual program updates to keep up with the ever-changing technology costs us an additional $10,000 per year. Nevertheless, having state-of-the-art equipment is essential in servicing your vehicle, and ultimately in saving you money. Proper diagnosis is the goal.
