New Mercedes Sprinter 2.2 CDI Turbo – Ref. 54399880049

A new turbo designed for the Sprinter's demanding commercial use

The Mercedes Sprinter is first and foremost a working vehicle: daily deliveries, heavy payloads, frequent stops and long periods of engine running. This type of use puts considerable strain on the forced induction system, particularly on the 2.2 CDI engine fitted with a twin-turbo system with variable geometry. Repeated pressure build-ups, prolonged idling during deliveries and load/unload cycles naturally accelerate wear on the bearings and actuators if maintenance is not kept up to scratch. This new turbo, compatible with reference 54399880049, is offered as a replacement for a worn or faulty unit on this model.

Compatibility with the Sprinter 2.2 CDI

This turbocharger is specific to Mercedes Sprinter vehicles with an engine capacity of 2148 cm³, for the 2.2 CDI 129 and 150 hp engine, on engine codes OM 646.986, OM 646.989 and OM 646.990. This twin-turbo assembly combines a low-pressure stage and a high-pressure stage to optimise engine filling across the entire rev range, which explains its particular sensitivity to oil quality and circuit cleanliness. Before placing an order, it is recommended that you check the reference marked on the old turbo or on the vehicle's engine plate, as several closely related versions may have been fitted to this model depending on the production period.

Straightforward sale – nothing to return

This new turbo is sold as a straightforward sale: no used part needs to be returned, and there is no return, collection or deposit to manage. A single delivery is all it takes to receive the new turbo ready to be fitted. It is covered by a 12-month parts warranty, subject to fitting being carried out by a professional. Payment can be spread over up to 10 instalments to help manage the cost of the repair.

Tips for a reliable fit on the Sprinter

On this twin-turbo engine, the majority of premature failures stem from insufficient lubrication: unsuitable oil grade, delayed oil changes or a clogged oil filter will quickly weaken the bearings on both stages. A blocked air filter or a cracked intercooler can also disrupt intake pressure and accelerate wear. Before fitting the new turbo, it is advisable to check the condition of the oil circuit, replace any tired hoses and ensure there are no residues in the air intake or exhaust manifold. When starting up for the first time, priming the oil before the initial start allows the bearings to be properly lubricated and minimises any risk of dry running.
