Reconditioned Volkswagen Crafter Turbo

Which turbo for a Volkswagen Crafter TDI: 2.5 or 2.0, and what engine code?

The answer comes down to two things: the engine generation and the engine code stamped on the identification plate — not simply the quoted power output. A Crafter 2.5 TDI 136 hp and a Crafter 2.0 TDI 136 hp take entirely different turbos, and within the 2.0 TDI, five power outputs — 109, 114, 122, 136 and 140 hp — exist alongside several distinct engine codes (CXFA, CXHA, CXHB, DAUA, DAUB, DAUC, DMZE, DNAE, CDBA, CNFA, CNFB, CKTB, CKTC, CSLA, CSLB, CSLC, CKUB, CKUC, CSNA), which multiplies the manufacturer references.

2.5 TDI: codes BJL, BJJ, BJK, BJM, CECA, CECB, CEBA, CEBB

The 2.5 TDI block was fitted to the first-generation Crafter in 88, 109, 136 and 163 hp outputs. These engines share a variable-geometry architecture with an integrated wastegate, but the references differ according to power output: the 49377-07440 family covers the lower-power versions (076145701B, 076145701E, 076145701F, 076145701H…), while the 136 and 163 hp versions call for the 49377-07515 or 49377-07535 family (076145701Q, 076145702C, 076145702D…). Mixing up the two families is the most common mistake on this generation. The 2.5 TDI is sensitive to degraded oil: the CHRA bearings deteriorate quickly if service intervals are exceeded under heavy loaded use.

2.0 TDI: a wide range of references to identify precisely

The second generation moved to the 2.0 TDI, with a power range spanning 109 to 163 hp. The variable-geometry turbos in this family come in several manufacturer references (04L253014A, 04L253014C, 04L253014F, 04L253014L, 04L253014M, 04L253014N, 04L253056R for the 873767 group; 03L253014A, 03L253014C for the 803955 group; 03L145701R, 03L145715B, 03L145715K, 03L145873A for the 10009880113 group). On a high-mileage van, a blocked diesel particulate filter and oil vapour from the crankcase breather are the primary causes of actuator and variable-geometry vane failure. Typical symptoms include a whistling noise under load, black or blue smoke, and a loss of power when accelerating under load.Identifying the root cause of the failure — oil circuit, blocked DPF, air intake — is essential before returning the unit to service, otherwise the replacement part will deteriorate rapidly. All turbos offered for the Crafter are new.
