Hello, my wife is driving a Twingo 1.2 16V BJ 2003. For some time now the exhaust gas monitoring lights up. I had the error read out once in a free workshop and there the flaw could only be roughly narrowed. Suction pipe seal defective. I had the error deleted and wanted to see if the lamp lights up again. After about 2 weeks also the exhaust gas monitoring again lit up. In addition, however, the Twingo now sometimes also goes out and it lights up then additionally the L square and a serrated line in it. It goes out again when you give gas and the car runs out again. Now after Renault and error read out. There they told me the throttle valve housing had to be changed. I am a bit unsure now, because with the throttle valve protector does not light up the exhaust control or yet? I have read once that the Twingo has problems with the throttle valve housing and if it cleans it would be enough then often. Is anyone confirming that? See you then Andreas
