Mitsubishi Pajero Turbo

Pajero diesel: why can the same 3.2 DI-D take three different turbos?

This is the classic pitfall with the Pajero: the 3.2 DI-D comes in three power outputs — 160, 165 and 170 hp — which do not all share the same turbo reference. The codes 49135-03412, 49135-02921 and 49135-03130 each correspond to distinct specifications on the 4M41 block. The same logic applies to the older blocks: the 4D56 of the 2.5 TD and the 4M40 of the 2.8 TD together generate around ten cross-references (including 49177-01501, 49177-01514, 49377-03203), sometimes for model years that are very close together. The engine code stamped on the block is the only reliable identifier; engine capacity alone is not enough.

2.5 TD and 2.8 TD: two blocks, two distinct turbo families

The 4D56 / 4D56T (2.5 TD) and the 4M40 (2.8 TD) are fitted to the Pajero generations III and IV. These fixed-geometry turbos with wastegate are prone to failures caused by oil circuit contamination — carbon build-up in the CHRA feed pipe, bearing wear from insufficient lubrication after a cold start without warm-up. Typical symptoms include a sharp whistling noise under acceleration, blue-grey exhaust smoke and a noticeable loss of power. Before any replacement, it is essential to identify and address the root cause (oil quality, blocked feed pipe, turbo gasket on the intake side) to prevent a rapid recurrence.

3.2 DI-D: variable geometry and multiple references on the 4M41

The 4M41 of the 3.2 DI-D uses a variable-geometry turbo whose actuator controls the vanes according to load. Contamination of the EGR circuit or the diesel particulate filter degrades intake air quality and accelerates wear on the vanes and bearings. Entering limp mode with power restriction is often the first warning sign. Several manufacturer references coexist for this block depending on the power output: ME201593, ME201677, ME202578 for the 160/165/170 hp variant, 49135-03200 and ME202446 for other variants. For the 2.8 TD only, EDEN BOITES also offers a reconditioned turbo option in addition to the new turbo available across the full engine range.
