A combined emission control device and exhaust gas heat exchanger for connection to the exhaust gas flow from an engine of a motor vehicle is disclosed having a number of exhaust gas transfer passages and a number of coolant passages so as to permit heat to be transferred from exhaust gas flowing through the exhaust gas heat exchanger to coolant used to supply heating for a cabin of the motor vehicle. The exhaust gas heat exchanger includes a tapping to permit cooled exhaust gas to be extracted for use in a Low Pressure Exhaust Gas Recirculation system. The exhaust gas heat exchanger thereby provides dual functionality being able to recuperate heat for use in a cabin heater and cool exhaust gas for use in the Low Pressure Exhaust Gas Recirculation system.
