EGR Valve for Mercedes-Benz A-Class (W169) and B-Class Sports Tourer (W245)

Description

Check part compatibility by using our vehicle filter options below. If you find your car, this part is compatible.

The EGR valve (Exhaust Gas Recirculation valve / vanne AGR) is a critical emissions-control component installed on diesel engines to help reduce nitrogen oxide (NOx) emissions while improving combustion efficiency. By recirculating a portion of exhaust gases back into the intake system, the EGR valve lowers peak combustion temperatures and reduces harmful exhaust output. Over time, soot and carbon buildup can cause the valve to stick or fail, leading to poor performance and engine management warning lights — making replacement essential when symptoms arise.

This EGR valve is compatible with Mercedes-Benz A-Class (W169) and B-Class (W245) diesel models that use OEM part references such as A6401400760 / 6401400760 / A6401401460 / 6401401460 / A6401401860, specifically for the OM640 engine family.

Key Benefits

Restores Emissions Control
The EGR valve helps maintain low NOx emissions by recirculating exhaust gases into the combustion process, helping your vehicle meet emissions standards and perform as designed.

Improves Engine Performance
A functioning EGR valve contributes to smoother idle, better throttle response and more consistent power delivery — especially at low to mid engine speeds. Faulty valves can disrupt the air-fuel mixture and lead to drivability issues.

Reduces Carbon Buildup Impact
Diesel engines are prone to soot accumulation in the EGR system. A new valve helps eliminate sticking or blocked operation that could otherwise impair engine efficiency.

OEM-Equivalent Fitment
Designed to match original Mercedes-Benz specifications for W169 and W245 applications, this valve installs directly with no modifications required when the part reference matches your vehicle.

Supports Long-Term Reliability
Whether replacing a worn OEM unit or upgrading a deteriorating aftermarket part, fitting a quality EGR valve helps prolong engine component life and maintain emissions compliance.

Frequently Asked Questions (FAQs)

Q: What does an EGR valve do?
A: The Exhaust Gas Recirculation (EGR) valve routes a regulated amount of exhaust gas back into the engine intake to lower combustion temperatures and reduce nitrogen oxide (NOx) emissions.

Q: What are the symptoms of a faulty EGR valve?
A: Common symptoms include rough idle, reduced engine power, hesitation on acceleration, increased fuel consumption, excessive smoke, and an engine management warning light.

Q: Which Mercedes models use this EGR valve?
A: This valve fits Mercedes A-Class W169 and B-Class W245 diesel models with OM640 engines — typically A160 CDI, A180 CDI, A200 CDI and equivalent B-Class variants. Always verify fitment with your VIN or existing part number.

Q: Can the EGR valve be cleaned instead of replaced?
A: In some cases, cleaning may temporarily improve operation, but heavy carbon deposits or mechanical wear usually necessitate a full valve replacement for reliable performance.

Q: Should I replace the gasket/seal?
A: Yes — always install a new gasket or seal when replacing an EGR valve to ensure a proper airtight connection and prevent leaks.
