Three years ago, the engine indicator appeared on the dashboard and, when taking the car to the agency, I was told the turbo had broken down. However, it was so expensive I did not replace it, and actually the turbo was working. The car jerked and pulled and the indicator appeared every now and then, causing a significant power loss. I went to other mechanics who told me the problem was an excess of pressure on the turbo and decided to cancel the EGR. The light continued appearing and, after a year, I returned to the agency. This time, they cleaned the turbos properly and connected the EGR and the problem was solved. I was so disappointed they hadn't done exactly that a year before. I wanted to share my experience in case someone has my same problem.
