To help you find your way around, we would like to answer the most important questions on this topic in advance.

What exactly is engine damage and how can it be recognized?

As with an illness, damage to the engine can also be identified by various “symptoms”. Does your Smart consume significantly more water or oil and do you therefore have to refill it more and more frequently? Do you also notice that the engine runs “roughly” and that engine performance decreases? Maybe your little car even emits a strong wave of oil when starting? - Then you should pay attention! These signs are often the first harbingers of such damage!

Reasons for the increased oil consumption can be defective oil scraper rings or a broken partial load ventilation. But a valve stem seal that no longer works or a defective turbocharger can also cause this problem. Oil consumption often increases to up to one liter per 1000 kilometers! Although the engine of your Smart will continue to run at this level for a while, the performance will decrease significantly.

What should definitely be done in the event of an engine failure?

So if you discover these “symptoms” on your Smart, you need to act quickly. Give your vehicle a comprehensive check to diagnose impending engine damage. If it is determined that a cylinder is no longer working properly, engine damage is the diagnosis. In order to save your vehicle, a replacement engine must be installed.

What is a replacement engine?

A replaced engine means that the engine of a vehicle has been repaired. This replaces an identical original motor and is also known as an AT motor or ATM. There are standards and regulations for these in Germany.

Engines must be maintained to strict quality standards to continue to be reliable. A number of wearing parts are replaced. These include, among other things, seals, pistons and valves, etc. Other components are taken over and reused for the replacement engine. This applies e.g. B. for the fuselage or the head of the engine.

A defective engine is completely overhauled and repaired by honing and slightly boring the cylinders, replacing the bearings and overhauling the cylinder heads. The mileage does not change because the remaining components of the vehicle have already traveled the route shown. To ensure that the value of a car increases after installation, the date of installation and the kilometers driven beforehand are recorded in a service booklet.
