Exhaust Volkswagen Crafter

The Volkswagen Crafter exhaust system is prone to several frequent failures, especially on the 2006-2016 and 2016+ generations. Common problems include faulty NOx catalytic converters, defective sensors, EGR valve blockages, and rear silencer wear. These issues often trigger limp mode, engine warning lights, power loss, and increased fuel consumption.

Key component failures include:

• NOx Catalytic Converter: Thermal damage and cracks due to excessive heat.
• Exhaust Sensors: Cause performance drops, warning lights, and higher fuel usage; OBD diagnostics recommended.
• EGR Valve: Blockages leading to limp mode or warning lights, requiring cleaning or replacement especially on first generation engines (2.5 TDI, 2.0 TDI).
• Rear Silencer: Typically needs replacement between 60,000 and 130,000 km; checked during MOT for noise or leaks.

Recommended maintenance includes:

• Complete inspections and cleaning of intercoolers, pipes, valves, and bi-turbo components to ensure proper air flow and avoid blockages.
• Paying attention to generation-specific issues: the 2006-2016 model is more vulnerable to mechanical and electronic faults, while the 2016+ model has improved but requires emission and transmission checks.
• Regular professional diagnostics to prevent limp mode activation and maintain vehicle reliability over hundreds of thousands of kilometers.

Following these guidelines helps maintain exhaust quality and ensures optimal engine performance and emission control.

The rear silencer usually requires replacement between 60,000 and 130,000 km. It should be inspected regularly as part of vehicle servicing and is checked at the MOT control for excessive noise or exhaust leaks. Using original quality silencers and timely replacement ensures regulatory compliance and reliable performance.

Exhaust sensor malfunctions, particularly in models like the 2008 Crafter, commonly result in reduced engine power, illuminated engine warning lights, and increased diesel consumption. Sensors monitor emission levels continuously and faulty readings cause the vehicle’s control system to enter limp mode, reducing performance to protect engine integrity. Proper OBD diagnostics and replacement of defective sensors restore normal function.

The Exhaust Gas Recirculation (EGR) valve reduces nitrogen oxide emissions by recirculating exhaust gases back into the engine intake. In Volkswagen Crafter diesel engines, especially early 2.5 TDI and 2.0 TDI types, the EGR valve can get blocked or clogged. This obstruction causes warning lights, limp mode operation, and emission failures. Regular cleaning or replacing the EGR valve is necessary to maintain emission standards and engine reliability.

• EGR blockages decrease engine efficiency.
• Timely maintenance prevents costly repairs.
• A functional EGR valve supports compliance with Euro emission standards.

Always opt for high-quality original components for replacement to ensure durability and optimal performance.
