Used OEM EGR Valves for Trucks, Lorries & HGVs

Used truck EGR Valves

EGR Valves are part of the exhaust and emissions system on many modern trucks, lorries and HGVs. The EGR system, or exhaust gas recirculation system, helps control combustion temperature and emissions by routing a measured amount of exhaust gas back into the inlet side of the engine. On Euro 5 and Euro 6 vehicles this system is usually controlled by a combination of valves, pressure control solenoids, sensors, pipework, coolers and electronic management. When the correct EGR Valves and control components are fitted and operating correctly, the engine management system can regulate exhaust recirculation accurately without causing unnecessary warning lights, poor running or emissions faults.

VRA Truckparts lists genuine used OEM EGR Valves and related EGR control parts removed from dismantled commercial vehicles. Current stock is limited and changes depending on the donor trucks being broken, so the exact items available in this category may vary. A typical example is a genuine used MAN TGX TGS solenoid valve / EGR pressure control valve with MAN part number 51521600005, also associated with reference 51521600001, suitable for checking against Euro 5 and Euro 6 MAN TGX and MAN TGS applications. Each listing should be checked carefully for the part number, plug style, valve body layout, mounting points, included brackets and visible condition before ordering.

What you will find in the EGR Valves category

This category is focused on used OEM EGR Valves and closely related exhaust emissions control components for trucks and commercial vehicles. Because these are used genuine parts from donor vehicles, availability depends on what has been dismantled and catalogued. Some listings may be complete EGR valve assemblies, while others may be pressure control valves, solenoid valves or related units used to operate or regulate the EGR circuit.

• Used OEM EGR Valves for truck and HGV exhaust emissions systems, when available.
• EGR pressure control valves used to regulate vacuum, air pressure or electronic control signals in the EGR system.
• Solenoid valve units such as MAN TGX and MAN TGS EGR pressure control references 51521600005 and 51521600001.
• Valve bodies with attached solenoids, electrical plugs and mounting lugs where included in the individual listing.
• Euro 5 and Euro 6 emissions-related control components removed from donor commercial vehicles.
• Associated fittings, brackets, clips or connectors where these remain attached to the used part.
• Related exhaust and emissions parts may appear depending on current stock and how the donor vehicle was dismantled.

Truck brands & typical applications

The current product example in this category is linked to MAN TGX and MAN TGS applications, specifically a genuine used MAN EGR pressure control solenoid valve with part number 51521600005 and related reference 51521600001. These models are common in long-haul, distribution, construction and fleet work, and their emissions systems can vary by engine, model year and Euro standard. Buyers should not rely on model name alone. MAN TGX and TGS parts can differ between engine families, chassis configurations and Euro 5 or Euro 6 versions.

• MAN TGX applications may use EGR Valves or pressure control components that look similar but have different references.
• MAN TGS donor vehicles can share some emissions control components with TGX models, but part numbers must still be matched.
• Euro 5 and Euro 6 trucks often have more complex exhaust and emissions control systems than earlier vehicles.
• Other European truck brands may appear in this category in future if suitable used OEM EGR Valves are dismantled and listed.
• Always compare the OEM reference, connector shape, mounting position and pipe or control connections against your original part.

Why EGR Valves matters

EGR Valves matter because they are part of the system that helps the engine management unit control emissions, combustion temperature and overall running behaviour. On a heavy commercial vehicle, a sticking EGR valve, failed pressure control solenoid or incorrect replacement component can lead to fault codes, derate conditions, loss of power, rough running, excessive smoke, poor fuel economy or failed emissions checks. The EGR system works alongside other exhaust emissions components, so a fault in one part can sometimes appear as a wider engine management or aftertreatment issue.

For workshops and fleet operators, correct diagnosis and correct part matching are important. Replacing an EGR control component with the wrong version may not clear the fault and can create further downtime. Used OEM EGR Valves are often preferred where the original manufacturer fit, plug design, bracket style and control characteristics need to match the vehicle precisely. A genuine used MAN EGR pressure control valve, for example, should be compared by MAN part number rather than simply by visual similarity.

Typical reasons to replace EGR Valves

EGR Valves and related control components work in a hot, contaminated environment and can fail for several reasons. Not every running issue is caused by the valve itself, so the old part, diagnostic codes and surrounding pipework should be checked before purchase.

• Sticking, seized or slow-moving EGR valve operation caused by carbon build-up or exhaust contamination.
• Failed EGR pressure control solenoid causing poor control of the EGR circuit or recurring fault codes.
• Damaged electrical plug, broken pins, corroded terminals or wiring connector faults at the valve or solenoid.
• Cracked valve body, broken mounting lugs, damaged brackets or missing fixings after removal or previous repair work.
• Air, vacuum or pressure connection faults where hoses, ports or attached fittings have become damaged.
• Incorrect aftermarket or non-matching replacement part fitted previously, causing compatibility or calibration problems.
• Impact damage, heat damage or contamination from related engine, exhaust or emissions system faults.

How to choose the correct EGR Valves

Choosing the correct used OEM EGR Valves is mainly a matching exercise. Many parts look similar but are not interchangeable, especially on Euro 5 and Euro 6 HGVs. Before ordering, remove or inspect the original part where possible and compare the details against the listing photos and description.

• Check the truck make, model and generation, such as MAN TGX or MAN TGS.
• Confirm the engine type, engine code and emissions standard, especially Euro 5 or Euro 6.
• Match the OEM number, manufacturer reference and any alternative part numbers, such as 51521600005 or 51521600001.
• Compare the electrical plug shape, number of pins, connector angle and wiring position.
• Check the valve body shape, solenoid position, port layout and any hose or pressure connections.
• Compare mounting points, bracket layout, bolt spacing and any attached fittings.
• Look at the donor vehicle details where supplied, including model, year, engine and chassis information.
• Review all listing photos for visible condition, included parts and differences from your original unit.

If you are unsure whether a used EGR component will match your vehicle, use how to find the right truck part and compatibility and VIN checks before ordering. For emissions system components, a small difference in part number, plug or control layout can be important. Buyers should compare OEM numbers, part numbers, photos, donor vehicle details and the physical layout of the old part. VRA Truckparts can usually give clearer guidance when you provide the registration, VIN, original part number and photographs of the unit fitted to the vehicle.

Used OEM parts from dismantled trucks

VRA Truckparts supplies used genuine OEM truck parts removed from dismantled donor vehicles. EGR Valves and related control components are photographed and described with the information available at the time of listing. Where part numbers, OEM references, model details or condition notes are visible, these are included to help trade buyers make an informed choice. The example MAN TGX TGS EGR pressure control solenoid valve is described as a genuine used MAN part removed from a vehicle in used condition and tested for basic operation before dismantling, but buyers should always read the individual listing for the exact condition statement on any item.

Used emissions components can show normal marks from service, heat exposure, handling and removal. This is expected with genuine used HGV parts. What matters is whether the reference, connector, mounting layout and visible condition match the vehicle repair requirement. For more information about how used truck parts are removed and handled, see our dismantling and quality process and trucks we dismantle.

Related categories

EGR Valves sit within the exhaust and emissions area of a commercial vehicle. If the fault has not been fully diagnosed, it may also be worth checking related exhaust, emissions, engine management and sensor components on the vehicle before ordering. EGR faults can sometimes be connected to blocked coolers, split pipes, damaged wiring, failed pressure sensors or broader engine management issues. Current related stock will depend on what donor vehicles are being dismantled and listed.

When comparing parts, keep your original component to hand and check all references before purchase. If your workshop is dealing with a fault code rather than a visibly damaged part, confirm the diagnosis first to avoid replacing a working unit. You can also use compatibility and VIN checks to help match the correct used OEM part where the listing information alone is not enough.
