Hello I have run since August 2011 a Forester built in 2003 2.o ltr. 125 Ps approx. 118000 km. The car is ok, only at different intervals the engine control light goes on. I had the error read out diagnostic Lambda probe. My workshop wanted to install me a complete Kat. with which I do not agree. I checked with the Dekra the exhaust values was everything ok. Maybe someone can help me. Thank you in advance
