A new turbo designed for the real-world use of your Mercedes E-Class
The E-Class is a saloon frequently used for long journeys on A-roads and motorways, sometimes towing a trailer or carrying a heavy load in the boot. This kind of use places considerable demands on the V6 diesel's turbocharger, which must deliver consistent boost pressure over extended periods. Driving habits such as rapid acceleration from cold starts, or repeated short trips that never allow the turbo to reach operating temperature, accelerate wear on the bearings and lubrication system. For this model, a new turbo compatible with reference 781743-5003S restores the original boost pressure and engine responsiveness.
Compatibility with E-Class engines
This new turbo is compatible with the following engines fitted to the Mercedes E-Class: 320 CDI, 320 T CDI, 300 CDI, 350 CDI and 350 BlueTEC, all based on the OM642 2987 cm³ diesel block. Before ordering, it is essential to check the reference number on your old turbo or on the engine plate, as certain variants of the OM642 block were fitted across several generations of the E-Class with very similar references.
Warranty and delivery for this E-Class turbo
This new turbo for the Mercedes E-Class is sold as a straightforward purchase: it is a new part and there is nothing to return — the order involves a single delivery. It carries a 12-month parts warranty, subject to fitting by a qualified professional. Payment can be spread over multiple instalments, in up to 10 instalments.
Advice before fitting this turbo to your E-Class
On the OM642 block, premature turbo failure is often caused by insufficient lubrication, incorrect oil grade, missed oil changes, or a clogged air filter disrupting the intake. Before fitting, check the oil circuit, the condition of the hoses, and the cleanliness of the air intake and intercooler — these factors directly affect the longevity of the new turbo. When starting up, prime the oil circuit before the first engine start to ensure immediate lubrication of the bearings.
