So that you can find your way around better, we would like to answer the most important questions on this topic in advance.

What 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 use significantly more water or oil and do you therefore have to refill it more and more frequently? Do you also notice "rough" engine running and a drop in engine performance? Maybe your little runabout even emits a strong oil wave when you start it? - 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 trigger this evil. Oil consumption often increases to up to one liter per 1000 kilometers! The engine of your Smart will continue to run with this consumption at times, but the performance will decrease significantly.

What should be done in case of engine damage?

So if you discover these “symptoms” on your Smart, you need to act quickly. Subject your vehicle to 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?

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

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

A defective engine is 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 covered the displayed route. To ensure that the value of a car increases after installation, the installation date and the kilometers previously driven are entered in a service booklet.
