Product Introduction
EGR Cooler (OE: 9807593080)
This EGR cooler is a core component of the engine emission control system, specifically engineered for mainstream diesel passenger vehicles in European and American markets. It is primarily designed for 2.0L TDCi and HDi diesel engines found in Ford, Peugeot, and Citroën vehicles.
As a critical element of the Exhaust Gas Recirculation (EGR) system, its main function is to cool exhaust gases before they re-enter the intake manifold. By reducing peak temperatures and oxygen concentration within the combustion chamber, this cooler significantly inhibits the formation of nitrogen oxides (NOx). This helps vehicles comply with stringent Euro emission standards while simultaneously optimizing fuel economy.
Precision Cooling for Engine Protection
Featuring a high-efficiency heat exchange core design, this cooler significantly reduces the temperature of circulating exhaust gases from hundreds of degrees Celsius to a safe operating range. Cooler exhaust gas not only helps reduce engine knocking but also extends the service life of the EGR valve and the entire intake system.
High-Pressure & Leak-Proof Design
The housing is crafted from high-temperature resistant and corrosion-resistant aluminum alloy. Its compact structure (typically around 18-20cm in length) enhances heat dissipation efficiency while maintaining structural integrity. The precision-engineered interfaces ensure a perfect seal, eliminating the risk of leaks after installation.
High-Efficiency "Plate-Fin" Structure
Optimized internal fin density combined with vacuum brazing technology eliminates the leakage points often found in traditional tube-and-fin welding processes, ensuring superior durability.
OE Standard "Plug-and-Play" Fitment
Manufactured strictly according to original OE specifications, this product features precise mounting holes and pipe interfaces. It requires no cutting or modification, allowing for a direct replacement of old components and significantly reducing labor costs for repair shops.
Citroën: Relay, Jumpy, Dispatch, C4, C5, DS4, DS5 (2.0 BlueHDi)
Peugeot: Boxer, Expert, Traveller, 308, 508, 3008, 5008 (2.0 BlueHDi)
Ford: Transit, Mondeo, S-MAX, Galaxy, Focus, Kuga (2.0 TDCi)
Technical Parameters
Common Applications & Problem Solving
1. Passing Emission Tests (MOT/TÜV)
When an EGR cooler fails due to internal carbon buildup or leaks, the Exhaust Gas Recirculation system malfunctions, causing Nitrogen Oxide (NOx) emissions to spike drastically. In Europe and other regions, this often results in a failed MOT or annual vehicle inspection. Replacing the faulty unit with a high-efficiency, reliable EGR cooler is the key solution to bringing the vehicle back into compliance and getting it back on the road legally.
2. Restoring Engine Performance & Clearing Warning Lights
If you notice the following symptoms, it is a strong indication that your EGR cooler needs replacement:
Loss of Power/Sluggish Acceleration: Uncontrolled exhaust gas recirculation disrupts the engine's normal air intake.
Increased Fuel Consumption: Caused by reduced combustion efficiency.
Check Engine Light: The On-Board Diagnostics (OBD) system detects flow abnormalities within the EGR system.
Installing a new cooler immediately restores engine responsiveness and fuel economy.
3. Essential for Commercial Fleets & Logistics
For logistics vehicles covering hundreds of kilometers daily, the EGR system operates under constant high load, making the cooler prone to failure from thermal stress or carbon buildup. For high-volume commercial vans like the Ford Transit, Citroën Jumpy, and Peugeot Expert, the EGR cooler is a critical maintenance item. Ensuring the reliability of this component is vital for minimizing vehicle downtime and keeping your fleet running efficiently.
4-Step Installation Process
Step 1: Drain the coolant/oil system.
Step 2: Remove the old EGR cooler assembly.
Step 3: Fit the new cooler (Recommended: Replace O-rings and gaskets).
Step 4: Fasten connections, refill fluids, and bleed the system.
Frequently Asked Questions (FAQ)
Q1: Is this an electric or mechanical water pump? What is the voltage?
A: This is a fully Electric Water Pump. It operates on a standard 12V DC input, compatible with most passenger vehicle electrical systems. It receives commands from the Engine Control Unit (ECU) via PWM (Pulse Width Modulation) signals to achieve stepless speed regulation. Compared to traditional mechanical pumps, it controls engine temperature more precisely, thereby reducing fuel consumption.
Q2: How can I tell if my water pump is actually bad, rather than it being a sensor or air pocket issue?
A: Common symptoms of a failing pump include:
Fault Codes: Scanning the OBD (On-Board Diagnostics) system reveals codes such as 2E81, 2E82, or 2E83 (BMW-specific codes), which typically point to the electric coolant pump.
Unusual Noises: After turning off the ignition, the pump should perform a self-test or run a post-cycle. If you hear a high-pitched whining noise or absolutely no sound (when the engine is hot), the pump is likely failing.
Overheat Warning: The dashboard suddenly displays "Engine Overheated, Drive Carefully," even though the coolant level is normal.
⚠️ Important Note: If you have just replaced the pump, we strongly recommend performing a "Bleeding Procedure." For BMW electric water pumps, a "Digital Bleeding" process via a diagnostic tool is mandatory. Without this, the pump may not circulate fluid, leading to a false diagnosis that the new part is defective.
Q3: Does the new pump require programming or coding after installation?
A: For this specific model (OE: 9807593080) on BMW E-series chassis vehicles, you must use a diagnostic tool (such as INPA or ISTA) to execute the "Coolant Bleeding Procedure" after installation. Please note that this is not ECU programming (flashing); it is simply an initialization routine to prime the pump and remove air from the system.
