Electrical System Service and Repair
Modern cars require the correct voltage to function properly. Your vehicle’s electrical system must be able to keep it’s charge while under load or offload and running.
In most modern vehicles, the charging system must provide 13.5 to 15.0 volts, depending on the vehicle. This voltage will be modulated by the vehicle’s internal computer for a reference signal (5 volts) for every sensor in your car. The signal operates on a feedback loop and will return to the computer after it has been changed by a variation in temperature or a ground signal. Your car depends upon this feedback signal to operate. A change in the input or output voltage caused by a weak battery, faulty alternator, or broken electrical connections will impact how your vehicle operates, and may cause some systems to fail.
If the battery voltage should fall below it’s required threshold, the sensors, relays, switches, electronic modules and computers will no longer be operating within the manufacturers performance parameters.
Factors Affecting Battery Performance
- Temperature: A battery that is too hot or cold will self-discharge. A common problem in Alberta is how at colder temperatures the reserve capacity can drop, making it difficult to start your car, or it may not start at all.
- If your vehicle has a loose belt or worn belt tensioner the the alternator will not function as well. It is possible that a fully discharged battery may freeze in cold weather and require replacement.
- Worn brushes, bearings or bushing may also contribute to an increased drain on the battery load during ignition.
- Additional drains on the battery, such as headlights left on, or accessories, can reduce the available power that your battery is able to supply the vehicles main systems.
- Short distance trips, with periodic stops, where the ignition is turned off and restarted will not allow the charging system to bring the state of battery charge up to full capacity, especially in winter.
- An older alternator may not be able to provide a charge at it’s intended capacity, and will lead to your battery voltage being lower than necessary. Eurotekk can replace an old alternator in your BMW, Audi, or Mercedes-Benz.
Supercharger Service and Replacement
Supercharged cars operate on similar principals to any other motor vehicle; however, there are a number of significant differences in the required maintenance and service of these high performance vehicles. In a supercharged car, extra air is forced into the engine to create more power. This is called ‘forced induction’ and it puts the engine under stress on the engine to operate with forced induction. Since the supercharger is a ‘power-adder’, it will place extra stress on your car’s engine. As an owner of BMW, Audi, or Mercedes-Benz with a supercharger, there are certain precautions that you should take to keep your European import in performing at its best. In particular, supercharged cars are heavily dependant on their cooling system to keep them at a safe running temperature. Alin, the owner of Eurotekk Automotive and Performance Inc., can inspect your car’s supercharger system and note any areas of concern and suggest possible performance improvements.

As with any vehicle, there is required maintenance, and a high performance supercharged car will offer you a years of enjoyable driving if properly taken care of. We’ve include a short list of maintenance tips for your supercharged car:
- Engine Oil: Make sure that you follow your manufacturer’s recommended maintenance schedule and check your oil frequently to make sure your car is protected.
- Coolant and Temperature: Supercharged cars are especially vulnerable to damage from overheating. Always be aware of your temperature gauge and the condition of your coolant.
- Fuel: Having quality fuel is an especially important issue for supercharged cars. As a rule, a supercharged car should be run on premium gasoline.
- Air Filtration: A clogged air filter puts unnecessary strain on the supercharger and hurts performance.
- Transmission: Your transmission needs to transfer the additional power of a supercharged engine. It follows that there will be extra stress placed on your vehicle’s transmission, so always be aware of the condition of your transmission and service it regularly to keep it shifting and performing on par with your supercharged vehicle.
- As drivers, we tend to treat performance vehicles differently than other cars and drive them harder and faster. As a result, the tires, clutch, and brakes will wear down faster.
