VW/Audi 2.5 R5 TDI CR Engine Specs, Problems & Reliability. This new generation engine is based on the 2.5 R5 TDI and developed especially for Volkswagen Crafter in 2006. It is an inline five-cylinder (R5) turbocharged direct injection (TDI) diesel engine. It also has cast iron (GG350) cylinder block, SOHC driven by timing belt, aluminum 10-valve head, and hydraulic container tappets. Now the engine is equipped with the newest Typical Rail (CR) fuel system.
To satisfy the increased demands for power, acoustics, emissions, fuel usage and to extend upkeep intervals, numerous parts of the engine were redeveloped. This engine got a diesel particulate filter (DPF), electronic throttle control, EGR cooler and electronic EGR valve control, engine oil level sensing unit for increasing maintenance interval.
The engine enhanced by variable geometry turbocharger. All 80kW (107hp) versions and higher chooses an intercooler. Typical rail direct injection pump produces pressure approximately 1,600 bars. The operation of all systems is controlled by Bosch EDC16 electronic engine control unit (ECU).
The engine power variety is in between 65-120kW (87-161hp). This generation adheres to the Euro IV European emission standards. Inline five-cylinder engines were completely changed by more compact Volkswagen V6 TDI engines (3.0 TDI, 2.7 TDI) in 2011.
