Frequently Asked Questions
Is my BMW affected by the EGR cooler recall?
BMW issued recall campaigns 17V-953 and 18V-085 covering 2010-2017 diesel models with N47 and N57 engines. Check with your dealer using your VIN. Affected models include X3 F25, X5 F15, 5 Series F10, and 3 Series F30 with 2.0d or 3.0d engines.
What causes BMW N47/N57 EGR cooler failure?
The primary failure mode is internal coolant leakage through cracked heat exchanger tubes. Thermal cycling, high EGT (exhaust gas temperature), and carbon buildup accelerate degradation. The leaked coolant can contact hot exhaust components, creating a fire risk.
How much does BMW EGR cooler replacement cost?
OEM dealer replacement typically costs $2,000-$4,000 including labor. Aftermarket OEM-grade replacements like SUMEC SMC-LQ-129 offer significant cost savings while maintaining identical fitment and material specifications (aluminum housing, stainless steel core).
Can I drive with a failing EGR cooler?
Driving with a leaking EGR cooler is not recommended due to fire risk. If you notice coolant loss, white exhaust smoke, or sweet smell, have the vehicle inspected immediately. The recall was issued specifically because of fire risk from coolant contacting hot exhaust surfaces.
What is the OE number for BMW N47/N57 EGR cooler?
The primary OE number is 11717823210. Cross-reference numbers include 11717810871, 11717805447, 7823210, and 792001D. Always verify the OE number on your existing part before ordering a replacement.
