If you have ever wondered why replacing an engine harness is so expensive, you aren’t alone. It is one of the most essential parts of your car, and a problem with the wiring harness can be difficult to diagnose. The symptoms of a faulty engine harness can be as simple as the check engine light coming on or a sensor going off. In this case, it’s likely that the wiring harness is the culprit.
First, remember that the engine wiring harness is made from sturdy material, and is located deep inside the hood of your car. Your engine undergoes constant temperature changes, as well as constant moving. Accidents and damage to your car can also cause this harness to fail. Second, the wiring harness is made to be able to work with both retitled and branded vehicles. That’s why it’s crucial to get it checked if it needs to be replaced. Similarly, regular oil changes using a BMW oil change kit can prevent significant engine damage and maintain the overall health of your vehicle.
Third, the cost of engine wiring harness repair varies depending on the make and model of your car. If you’re replacing the entire engine, you should get a second opinion from an independent mechanic before purchasing the new harness. On average, a harness replacement will cost $1,500. This is one full day of labor. It would take 3.5 hours to install the harness and the related components, and another 0.5 hours to complete all the paperwork.
