Friends, let me tell you an incident that may be helpful. The 1.6 hdi engine was giving a low oil pressure warning for 12 seconds at first start every morning. And nothing else happened during the day. The oil cooler of the vehicle had just been changed 5 thousand km ago. The oil cooler was intact. We said, we changed it with the original, we changed the oil, it didn't work, we said it would be from the oil sensor, we changed it, and it didn't. We said it would be from the cartel, we said there are no dented scratches on the cartel, we said it would be because of the filter inside, and the strainer came out clean. The problem did not improve. Also, my car was constantly giving the error codes p1461 and p 1462. I was constantly clearing the obd device. The same codes were coming back the next day. These codes were coming back to some forums. .The inside of the turbo hoses and the turbo radiator had not been cleaned by the master. I thought I'd clean it myself and I took it out. It was filled with a considerable amount of oil. There was a lot of oil, especially from the radiator. I cleaned all the pipes. I drained the oil inside the radiator. There was a lot of oil in the throttle body as well. I did it cleanly. And all the problems disappeared. Is it because of the oil pressure? The error codes did not come back anymore. I do not know the exact mechanism of action. I guess the oil that the turbo pumps into the engine affects both the oil pressure and the angle of the egr or something. And the electronics of the vehicle are very sensitive. Maybe it will be useful for someone.
