Replacement engines from Mercedes-Benz – quality that you can depend on.

Every Mercedes-Benz Genuine Remanufactured engine goes through a comprehensive remanufacturing process in which it is disassembled and cleaned, wear parts are replaced with new parts, and the engine is put back together again and subjected to rigorous testing. As a result, you can get your vehicle back on the road quickly after suffering engine damage. We simulate various driving situations on our test stands, taking into account the exacting quality requirements applicable to Mercedes-Benz Genuine Remanufactured engines. That is why you get the same guarantee and goodwill for genuine remanufactured engines as you do for new engines.

You choose the right engine variant depending on whether you want the vehicle to be operational as soon as possible or are more interested in making the complete overhaul of your engine as affordable as possible.

Your engine will remain a true original, because unlike all those independent engine workshops offering services such as engine repairs, complete overhauls and servicing, Mercedes-Benz uses only genuine parts. We also integrate the latest quality improvements in our remanufacturing process and test every engine on unique test stands at our manufacturing plant. To demonstrate our confidence in the quality of our genuine remanufactured engines, we offer a guarantee1) of up to two years. Our engines are designed to enjoy a second life. Durable component parts can often be remanufactured as many as four times.

There's nothing more frustrating than when your truck breaks down. As engine professionals from the manufacturer, we can act swiftly to help you out if you experience problems with your engine. It doesn't matter whether your engine is producing smoke, making noises, delivering less output than usual, misfiring during start-up or has sprung a leak or two over the years. We will find a good solution to any customer request.

At our Mercedes-Benz dealers, you can purchase a standard Mercedes-Benz engine or lower-cost alternatives such as a long block. The latter offers a good price/performance ratio, because engine damage does not always mean that the entire engine has to be repaired; instead, it is often merely a matter of replacing only the damaged components, such as the crankshaft, pistons, connecting rods, crankcase or engine block. Detachable parts that are still in good working order, such as the turbocharger, control units, engine wiring harness, water pump, common rail injection system, injectors and injection nozzles, and sometimes even the cylinder head, can be re-used.


What needs to be taken into account for the various engine repair options?

In the case of damage that is limited to a few specific detachable parts such as the turbocharger, component replacement may be the alternative that comes at the lowest cost. However, taking this route does present a considerable risk in older vehicles that another part could soon fail as well, and your vehicle could end up having to be repaired repeatedly at ever-increasing cost. That's why it is worth considering whether it might not be better to purchase a replacement engine, which comes with an excellent guarantee on the entire major assembly and will make driving a pleasure for a long time to come. Furthermore, engine experts always advise professional engine diagnostics to make sure that no other component parts have been damaged as a result of the single defective part. All it takes is a small metal chip from the turbocharger's compressor wheel, for example, to cause terminal engine damage.
