2011 TIFFIN PHAETON Engine Problems

THE MOTOR HOME MANUFACTURER IS TIFFIN MOTOR HOMES, RED BAY ALABAMA, THE COACH IS BUILT ON A FREIGHTLINER CHASSIS BUILT BY FREIGHTLINER CHASSIS. THE PROBLEM IS EXHAUST FUMES ENTERING THE INTERIOR OF THE COACH PRODUCING A STRONG DIESEL EXHAUST FUMES ODOR AND PROBABLY CARBON MONOXIDE. OUR RESEARCH INTO THIS PROBLEM INDICATES THAT THE EXHAUST FUMES ARE ENTERING THE COACH DURING THE REGENERATION CYCLE . WE BELIEVE THERE ARE TWO ISSUES INVOLVED. #1 THERE IS AN EXHAUST LEAK SOMEWHERE BETWEEN THE TURBOCHARGER AND THE DEF CATALYST SYSTEM. (WE BELIEVE THIS IS A FREIGHTLINER PROBLEM BECAUSE THEY BUILT THE ENGINE, EXHAUST SYSTEM AND CHASSIS). #2 THERE ARE LEAKS IN THE FLOOR, SIDEWALLS, COMPARTMENT OPENINGS OR ACCESS PANELS ALLOWING THE FUMES TO ENTER THE COACH. (WE BELIEVE THIS IS A TIFFIN MOTOR HOME PROBLEM BECAUSE THEY BUILT THE COACH). WE WILL ATTEMPT TO RESOLVE BOTH ISSUES WITH A VISIT TO TIFFIN AND FREIGHTLINER....
