Not sure you've found the right part?
Why does the turbo on the Mercedes E-Class 350 CDI fail?
On the OM 642 block fitted to the Mercedes E-Class 350 CDI, the turbocharger is under constant demand to maintain the boost pressure required by this 2987 cm³ diesel engine. The most common causes of failure on this engine are insufficient lubrication of the turbine, poor-quality engine oil or excessively long oil-change intervals, all of which lead to a build-up of deposits in the bearings and central housing. A clogged air filter, a cracked intercooler, or a driving style characterised by hard acceleration without a proper warm-up period will also accelerate premature turbo wear on this vehicle.

Points to check before fitting on the E-Class 350 CDI
Before installing this new turbo on your Mercedes E-Class, check the condition of the oil circuit, the cleanliness of the hoses, and that the air intake is free from obstruction. Pre-lubricating the turbo with oil before the first start-up ensures immediate lubrication of the bearings and prevents any dry running on initial start.
