M57 E38/E39
• EGR pipe designed with corrugated pipe (compensator)
• EGR valve mounted at inlet to air manifold
• EGR valve housing made of aluminium
EGR cooling will be subsequently added to ensure the M57 will also comply with the later exhaust emission standard EU-3. This cooling system will cool the recirculated gas by approx. 100 oC.
M67 E38

• Two EGR valves at inlet to air manifold
• EGR valve housing made of aluminium
• EGR cooling, thermostat-controlled
• EGR cooler installed in V-area under air manifold
• Cooled by approx. 100 oC by EGR cooling system
