Reconditioned Mercedes Sprinter Turbo – Ref. 54399880049

The Sprinter – a hard-working van that puts the turbo to the test

The Mercedes Sprinter is first and foremost a working vehicle: daily runs under load, urban deliveries punctuated by frequent stops, and long road journeys for chassis-cab and panel van variants. This intensive use – often with a fully laden vehicle – places considerable strain on the turbocharger of the 2.2 CDI engine, which must maintain constant boost pressure to cope with the payload being carried. Repeated high-rev driving, switching the engine off immediately after a hard run, and frequent short urban trips all accelerate wear on the unit if maintenance is not kept up to scratch.

Compatibility of the reconditioned turbo with the Sprinter 2.2 CDI

This reconditioned turbo is compatible with reference 54399880049 and fits the 2.2 CDI 129 ch and 2.2 CDI 150 ch engines of the Mercedes Sprinter, associated with engine code OM646DE22LA. Before placing an order, we recommend checking this reference directly on your old turbo or on your vehicle's registration document, as certain power variants may share closely related components.

Exchange basis and warranty for your Sprinter

This turbo is sold on an exchange basis: return of your old turbo is required, in accordance with our Terms and Conditions. It is only collected after the reconditioned turbo has been delivered and fitted, so your Sprinter is off the road for as little time as possible. The unit comes with a 12-month parts warranty, subject to fitting being carried out by a qualified professional. Payment for your order can be spread over several instalments, in up to 10 instalments.

Symptoms and causes of failure on the OM646 engine

On this 2.2 CDI engine, a loss of power under load, abnormal exhaust smoke, an unusual whistling noise, or an illuminated engine warning light may all indicate a failing turbo. The most common causes are insufficient lubrication due to poor-quality oil or missed oil changes, a clogged air filter allowing contaminants through, or a build-up of deposits in the circuit caused by frequent urban driving.

Advice before fitting on your Sprinter

Before installing the reconditioned turbo, check the oil circuit, the condition of the hoses, and the air intake to rule out any contamination. Also prime the turbo with oil before the first start-up, to ensure immediate lubrication of the bearings and a smooth initial run.
