Hello guys. There is a problem I can not solve on my head. I took it to the master a month ago due to the traction problem and as I guess, the turbo pressure was low. changed the valve master and the problem was fixed. But while driving on a steep slope with my car, I forced the car in 2nd gear and the husband left behind a dense black smoke. Just then, the air flow meter malfunction light came on. When he was in park for a few hours, he went out, but again when he exceeded 2500 times, he burned again. I mentioned it when I took it to the master for the undercarriage and told him to clean the air flow meter. When I got the car from the master, he said that a large piece of soot came out and he cleaned both the sensor and the air filter. "Use it a little bit, if it burns again, if it needs to be changed, we'll change it or if it is something else," he said. When I first got on the bus, I increased the speed and the malfunction lamp came on again around 2700 rpm. I haven't had the opportunity to take it to the master yet, and this time I wouldn't want to change the sensor again because I already changed it twice in 1 year. this replacement situation started as follows. I went 1 year ago due to traction problem and fuel leak. turbo changed, catalytic converter removed and pipe installed exhaust. The metal tube leading to the injection was torn, and the protrusion was replaced by the piece. and finally the air flow meter has changed. 4 5 months passed. He again gave air flow pain. Indeed, during these fuel leak events, a late diagnosis was made. then it broke down again. Anyway we changed it and it has not been a problem until now. Having a problem with the same piece for the third time in 1 year made me think that another problem occasionally happened to try. I'm sorry to tell you a little confused. I hope we find a solution.
