  Common Rail Direct Injection (CRDI) is another specification feature of the VW TDI engines. This type of fuel injection system atomizes the fuel into tiny droplets. As a result, the combustion process is more efficient, leading to lower emissions and higher power output.

• Emissions Control

  Many TDI engines have complex systems that reduce harmful emissions. The most notable emissions control system is the Selective Catalytic Reduction (SCR). The SCR system converts nitrogen oxide (NOx) into harmless nitrogen and water vapor. The SCR system uses a urea solution, which is injected into the exhaust system.

Regular maintenance is key to keeping the VW TDI engine in good working condition. Some of the maintenance requirements may include:

• Routine oil and filter changes
• Regular replacement of the air filter
• Regular replacement of spark plugs
• Regular checks and replacement of the timing belt (if worn out)
• Regular checks and maintenance of the cooling system
