By mixing exhaust with the air-fuel charge, it lowers combustion temperatures, reducing the formation of harmful nitrogen oxides (NOx) and improving efficiency under certain conditions. Modern vehicles may use electronically controlled EGR valves for precise operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eExhaust Gas Recirculation (EGR) Valve Failure Symptoms\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRough idle or stalling, caused by the valve sticking open and letting in too much exhaust.\u003c\/li\u003e\n\u003cli\u003ePoor performance or hesitation, often from a clogged or stuck-closed valve restricting proper gas flow.\u003c\/li\u003e\n\u003cli\u003eCheck Engine Light (CEL) with related fault codes (e.g., P0401 “EGR flow insufficient” or P0402 “excessive EGR flow”).\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BMW","offers":[{"title":"Default Title","offer_id":43687206486052,"sku":"11718511638","price":149.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1352\/3759\/files\/1762826_x800_2e8e2df1-03a8-40f3-8bb7-c8dc69112af9.png?v=1772584049","url":"https:\/\/www.4x4andcamping.com.au\/products\/genuine-bmw-vacuum-unit-with-return-spring-11718511638","provider":"QIKAZZ 4x4 \u0026 Camping","version":"1.0","type":"link"}
