The explanatory texts for the questions were machine translated. More info

All explanatory texts were compiled in German and then machine translated. This may result in translation errors. However, this only refers to the explanations to the questions. The translations of the questionnaires were done by TÜV | DEKRA arge tp 21 and are exactly the same as the translations in the theory test. These translations are only available once you are logged in. All other translations on the website were done by a different translation agency.

An einem Fahrzeug sind Motor und Schalldämpfer „frisiert“. Welche Folgen kann das haben?

Der Schadstoffausstoß wird größer
Engine settings and exhaust system are optimally coordinated by the manufacturer. So you can reach while driving and low fuel consumption and low pollution. If you change the settings or convert parts of the exhaust system, there is a risk of increased pollutant emissions, as the settings in the vehicle are no longer matched.
Der Kraftstoffverbrauch sinkt erheblich
If I myself am able to significantly reduce fuel consumption through changes to the exhaust system or the engine, then the manufacturer probably can. He would have certainly done it to sell his vehicles better. It is therefore very unlikely that I can significantly reduce fuel consumption through conversions.
Die Lärmbelästigung nimmt zu
The manufacturer has used appropriate parts that have been approved by the Federal Motor Transport Authority and thus also comply with the standards for noise protection. Therefore only approved parts should be used. In no case may one modify the parts installed by the manufacturer or install others, because then possibly the standards for the noise protection are exceeded.
