DIY car repair common factsDIY car repair – common facts

Only one or two decennia ago, DIY replacement of many car parts in model series of all current manufacturers were very common. A skilled survey of the engine and a private car hoist sufficed to perform a DIY replacement of brakes, shock absorbers and even gearboxes. Although this is still possible, over the years it has become increasingly difficult due to the growing proportion of car electronics. More and more car components are equipped with sensors and electronically controlled.

Even though DIY replacement of minor car parts is still possible, their number is shrinking. Particularly electronic car components are not for laymen. Faulty configuration can in the worst case prevent the car from starting or lead to unsafe interpretation of the driver’s data. The most important touchstone for DIY car repair is the observation if it concerns mechanical repair or whether intervention in the car electronics is required.
