Product Introduction
Designed specifically for BMW vehicles, this Exhaust Gas Recirculation (EGR) Cooler is a critical component of your engine's thermal management system. It serves as a direct replacement for OE number 11717790065, and is fully compatible with renowned international brands such as VEMO (V20-63-0047) and HELLA (8ME 376 750-761).
Engineered to lower exhaust gas temperatures within the EGR system, this cooler effectively suppresses Nitrogen Oxide (NOx) emissions. It not only ensures your vehicle meets stringent environmental regulations but also optimizes fuel economy. As a dedicated manufacturer exporting to the US and European markets, we specialize in premium engine components including EGR valves, throttle bodies, and coolers, delivering OEM-level quality directly to you.
High-Efficiency Heat Exchange: Designed with a tube-shell or plate-fin structure, this cooler maximizes the heat dissipation area. It rapidly cools exhaust gases from hundreds of degrees Celsius down to optimal temperatures, ensuring maximum engine intake efficiency.
Water-Cooled Technology: Utilizing engine coolant circulation, this water-cooled design provides more stable exhaust temperature control compared to air-cooled alternatives, while offering a compact structure that saves valuable engine bay space.
OEM-Quality Standards: Manufactured in strict accordance with the ISO/TS 16949 quality management system. Every unit undergoes 100% airtightness testing to guarantee absolute sealing under high-pressure and high-heat conditions, completely eliminating the risk of leaks.
Corrosion-Resistant Materials: The main body is crafted from lightweight aluminum alloy and treated with specialized surface coating. This advanced finish resists corrosion from exhaust condensate and acidic substances, ensuring an extended service life.
This EGR cooler is specifically designed for BMW vehicles equipped with diesel engines:
BMW 1 Series: E87 (2004-2007)

Highway Cruising: Ensures stable EGR cooling performance during long drives, maintaining engine bay thermal balance and preventing power loss.
Heavy-Duty Load: Fits 520d, 525d, 530d, and 535d. Effectively reduces engine load and protects the turbocharger system when fully loaded or towing trailers.
Solution: Restores lost power in high-mileage diesel engines.
Application: Mid-to-large SUVs and Sports Activity Vehicles.
Off-Road & Unpaved Roads: Provides superior cooling under low-speed, high-load conditions, protecting the EGR system from overheating damage.
Towing & Hauling (US Market Focus): Designed for the extreme thermal management demands of towing RVs or boats. This cooler is a critical safety and performance component for these heavy-duty tasks.
Engine Compatibility: Covers 2.0d, 3.0d, xDrive30d, xDrive35d, and 3.0sd high-performance diesel engines.
Application: Compact hatchbacks and luxury GT coupes/convertibles.
Sport Driving: Fits 118d, 120d, and 635d. Ensures responsive powertrain performance during aggressive driving or mountain roads, reducing heat-induced protective power limits.
Solution: Fixes failed emissions tests (such as TÜV or MOT) caused by EGR system malfunctions.
Product Operate Guide
Step 1: Drain Coolant. Safely drain the old engine coolant from the system.
Step 2: Remove the Old Cooler. Unbolt and carefully detach the old EGR cooler.
Step 3: Install the New Cooler. Mount the new cooler in place. (Pro Tip: Always check the vacuum valve on the radiator cap to ensure it is functioning properly.)
Step 4: Replace Seals. Install new gaskets/seals to guarantee a perfect, leak-free fit.
Step 5: Refill & Test. Fill the system with high-quality coolant up to the "FULL" mark. Start the engine and let it idle until the cooling fan engages, then recheck the coolant level.
FAQ
Q1: Is this EGR cooler air-cooled or water-cooled?
A: It is a water-cooled design. It utilizes engine coolant to lower the temperature of the recirculated exhaust gases. This design is critical because the cooler the air entering the engine, the more complete the combustion. This not only reduces Nitrogen Oxide (NOx) emissions but also improves fuel economy.
Q2: What is the cooler made of, and is it corrosion-resistant?
A: Our core and main components are constructed from premium-grade aluminum alloy (typically 3000-series, such as 3003) combined with high-temperature resistant plastic tanks. Aluminum offers excellent thermal conductivity (approximately 230 W/(m·K)). Furthermore, it is treated with an anti-corrosion coating to withstand the extreme heat and highly corrosive environment of the EGR system, fully meeting strict US and European durability standards.
Q3: Does this EGR cooler come with gaskets or installation hardware?
A: Yes, to ensure a perfect seal, this product includes the necessary gaskets/O-rings. We highly recommend always using new seals during installation. While the cooler comes with standard gaskets, to achieve optimal sealing performance (especially to meet strict European export standards), we also provide premium-quality matching seals.
Q4: Why does my vehicle keep throwing an EGR cooler fault code?
A: The most common issues with OEM coolers are internal leaks (which cause coolant to enter the exhaust system, resulting in white smoke) or clogging (due to excessive carbon buildup). Our product is specifically engineered to address these OEM flaws. The internal flow path is optimized to resist carbon accumulation, and our reinforced welding process effectively prevents cracking caused by thermal stress.
Q5: How do I properly bleed the cooling system after installation?
A: We highly recommend using a vacuum coolant filler tool for refilling. If doing it manually, leave the radiator cap open after installation, start the engine, and let it idle until the thermostat opens (you can verify this when both the upper and lower radiator hoses are equally hot). Keep adding coolant until all air bubbles are completely purged. Failing to properly bleed the system can lead to poor cooling performance.
