CLK 200 Kompressor (M271 1.8L) Running rich and high CO emission
Hi! My car recently failed a emissions test because of too high CO. The car seems to be running rich too. I have not noticed the car running worse/rough or smell from exhaust but fuel consumption feels exsessive. The car is throwing the following DTC codes: P0170, P0137, P0172, P0138, P0136...- Sander11
