Engine damage?

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

Every Mercedes-Benz replacement 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. Our test stands simulate a range of driving situations to ensure the stringent quality requirements of Mercedes-Benz remanufactured engines. As a result, even commercial customers receive the same guarantee¹⁾ they would for a new engine.

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 remains an original – because unlike when independent engine repair workshops offer services such as engine repairs, maintenance or general overhauls, Mercedes-Benz uses exclusively 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. Our guarantee¹⁾ of two years means you can enjoy trouble-free motoring with your genuine remanufactured engine. 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 annoying than a broken-down vehicle. 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 not only a standard Mercedes-Benz engines but also a range of cheaper parent engine alternatives such as the basic engine, long block, long block plus or short block (basic engine). 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. Any still-intact detachable parts such as the turbocharger, control units, engine wiring harness, water pump, high-pressure pump, vacuum pump, common rail injection system, injectors, injection nozzles and in some cases even the cylinder head can still be 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. Engine experts also always advise drivers to have their engine professionally diagnosed to ensure that no other component parts of the defective individual part have also been damaged. All it takes is a small metal chip from the turbocharger's compressor wheel, for example, to cause terminal engine damage.
