Technical characteristics of the CSUB 2.0 TDI 136HP engine

The CSUB 2.0 TDI engine with 136 HP belongs to a newer generation of diesel units used in Audi A4 B8, A5 8T, and Q5 8R models. The design, based on precise diesel fuel injection, ensures efficient combustion, good flexibility in the mid-RPM range, and predictable performance on the road and in the city. The use of TDI technology allows for a favorable compromise between dynamics and driving economy.

Selection, compatibility, and installation aspects

Before purchasing the engine, it is worth verifying the compatibility of the unit code with the vehicle documentation and the accessory configuration used.
