Remanufactured engines

The benefits of a remanufactured engine.

There are numerous benefits to a genuine remanufactured engine. One is that it is a quick method of replacement, as the comprehensive nature of the engine package with pre-assembled components means that it is simply a case of removing the old engine and installing the new one. This saves you time and reduces expenses. What's more, we maintain a permanent stock of more than 1,000 genuine remanufactured engines ready and waiting for one to be installed in your vehicle.

A genuine remanufactured engine exhibits excellent smooth running characteristics because all rotating component parts, such as the crankshaft and camshaft, are precisely balanced corresponding to the current technical status of new parts. By replacing wear and small parts with genuine parts such as belt pulleys, vibration dampers, critical pressurized lines, bearing shells and pistons, we ensure excellent reliability and durability for our genuine remanufactured parts.

With a Mercedes‑Benz Genuine Remanufactured engine, you receive a guarantee for up to two years²⁾, because we are certain that its functionality, longevity and quality will meet even the most exacting requirements. Engines undergo extensive testing and endurance trials. Each complete engine is tested on a test stand before dispatch to check that it meets the strict criteria for series production.

Not only that, but if your old engine is suitable for return, you will be reimbursed at an attractive rate credited to the purchase price.

What are the causes and symptoms of engine damage?

There's nothing more frustrating than a truck that has broken down. Yet after faithfully covering thousands of kilometers on the road, even the best engine needs an overhaul. By that time, the vehicle's guarantee or goodwill period will usually already have expired. An engine overhaul as a form of repair generally takes several days or weeks, whereas a replacement engine can be shipped immediately. You can return your previous used engine later on in exchange for cash, much like recycling deposit programs operated in some countries.

There is usually some advance warning of the need for a complete overhaul. The following may be signs of engine damage:

• Reduction in engine power when the vehicle is carrying a payload or driving uphill
• Occasional backfiring or misfiring when you start the engine
• Unusual noises in the engine compartment
• The malfunction indicator lamp (MIL) in the cockpit lights up to indicate engine problems
• High oil consumption or leaks
• High fuel consumption, high coolant or oil consumption, usually because there is a leak in the engine or some of its components
• The engine temperature is suddenly too high
• Discolored exhaust gas, usually bluish if there is oil in the combustion chamber or white smoke if water has entered the exhaust system
• Smoke or even flames coming from the engine

But what actually causes engine damage?

• Filling up with the wrong fuel, such as diesel instead of gasoline or vice versa
• Insufficient or incorrect oil and thus inadequate lubrication of the engine, which can lead to smoke, seizing or noises from the bearing shells, or even cracks and fractures in connecting rods or crankshaft damage
• Defective piston rings, which may cause piston seizure. In the worst-case scenario, broken parts can create a hole or crack in the engine block
• Insufficient cooling, leading to engine overheating
• Excessive engine speeds
• Water entering the engine (water ingestion damage)
• A defective timing chain or torn toothed belt
• Porous seals, such as the cylinder head gasket
• Dirt in the lines, which may result in an inadequate supply of fuel or oil
• Chip tuning may lead to engine damage as a result of engine overload or incorrect settings
• Contaminated oil can cause defects in the turbocharger, which may in the worst-case scenario introduce metal shavings into the system

What should you do if your engine is damaged?

First of all, a friendly tip: check the quality of your repair provider carefully. Sometimes, workshops can lure customers in with free towing services. Experience among customers on numerous Internet forums shows that in the case of costly damage in particular, it usually ends up being cheaper and less hassle to have repairs carried out by experts using high-quality original spare parts. Who can do that better than the people who developed and built the engine and have committed to a high standard of quality? In other words, Mercedes‑Benz. It is often quicker and less expensive to have the engine removed and replaced entirely than to pay several times for multiple separate repairs.
