Auto Electrical

Modern cars’ complex electrical systems require specialised diagnostic equipment for a comprehensive car service. At Bosch Car Service Pretoria Centre, our highly skilled auto electricians make use of sophisticated diagnostic tools to access your car’s data to identify the root cause of any electrical snags. We run diagnostic tests, using the results for troubleshooting and repairing of the electronic fuel injection (EFI for short) system and the advanced driver-assistance system (ADAS for short).

The electrical system is fundamental to the functionality of your car and is a power source for many parts, including the battery, alternator, and starter. Each car’s electrical system has its own nuances based on the make, model, and age of the vehicle. The latest models, especially, have complex computer systems that interact with various functions, including the brakes, steering, sensors and more. We troubleshoot each electrical component with the use of advanced in-house diagnostic tools, and our capable technicians with the know-how apply it efficiently. 

If your car experiences an electrical error, we advise that you contact our service centre as soon as possible for closer inspection. A car with electrical problems may not start or may even become inoperative while driving. During an auto electrical service, our electricians will identify and repair faults, which include open circuit, short circuit, and ground strap/cable connection faults, as well as resistance problems. We will also restore wiring harnesses and connectors along with the electrical wiring and solder repair of the car. Give us a call today to book your appointment.


These days, air-conditioning is standard on basically all cars. This is especially welcome on those sweltering days when one of life’s greatest pleasures is that refreshing blast of ice-cold air from the vents.

Our technicians at Bosch Car Service Centre repair and re-gas air-conditioning units, change the filters and inspect all the other components of your car’s heating, ventilation, and air-conditioning system.

An air-conditioning system has many elements that can cause issues, though. These include gas leaks and the failure of seals and bearings, as well as pipe blockages or sensor failures. The last component to fail is likely to be the costly compressor itself, which is generally caused by a lack of lubrication. During installation, oil is added to the refrigerant circuit to lubricate the components. When the gas leaks, so to does the oil, leading to the loss of the lubrication qualities, which then, ultimately, results in complete failure.

A car’s air-conditioning system loses around 10% of its refrigerant every year, which is why we recommend that it is serviced every two to three years. A failing system also contributes to the increased energy usage of your car. Thus, you will be paying more for petrol. Don’t wait too long for this important service. We are here and happy to assist.
