Hello, I drive a Mazda 323F 1.6l built in 2001 and have the following problem. In August of this year the engine control light went on. There was no jerking or similar. My wife then immediately drove to the Mazda workshop. There they told her that the cat was defective and made her an estimate of 1700 euros!!! We wanted to make a second opinion or a second estimate and drove to a friend. On the way there went the lamp plötzli Our friend simulated an AU and didn’t find any eye-catching values. He said that our car should be properly released – we drive mainly short distances in the city. For a week the lamp has been shining again. Now I am totally unsure. Wouldn’t it be better to buy a new cat now? I would be grateful for every constructive answer. Many greetings from Berlin Dirk
