NHTSA Complaint #11170653 — 2010 BMW X5

THE CHECK ENGINE LIGHT COMES ON AND I FEELS A DECREASE IN THE ENGINE POWER. I COULD STILL DRIVE, BUT NOT ACCELERATE AS FAST. ERROR CODE READS P2457. TOOK TO DEALER WHO RECOMMEND TO REPLACE THE EGR COOLER, NOT COVERED BY WARRANTY. I ALSO HAVE BEEN EXPERIENCING FOUL ODOR IN THE PASSENGER COMPARTMENT WHEN I TURN ON THE FAN OR HEAT FOR A WHILE PRIOR TO THE CHECK ENGINE LIGHT. I THINK THE ODOR AND THE EGR COOLER MALFUNCTION MAY BE RELATED. I HAVE READ ABOUT EGR COOLER FIRE HAZARD IN UK IN LATER MODELS OF BMW X5 35D DIESEL. BUT MY CAR IS BEFORE THOSE AFFECTED MODELS. I THINK BMW NA SHOULD EXTEND WARRANTY OF THE EGR COOLER TO MY MODEL (2010, E70) BECAUSE IT IS A NECESSARY PART OF THE EMISSION CONTROL SYSTEM AND ENGINE AIR INTAKE SYSTEM. I HAVE CONTACT BMW NA DIRECTLY BY PHONE, AND THEY HAVE NOT BEEN HELPFUL AT ALL.
