Since it was founded in 1909, Audi has been at the forefront of automotive innovation. It was the first to conduct crash tests, one of the first to use a dual-clutch gearbox, and in 1921, became the first German manufacturer to make a production car, the Audi Type K, with left-hand drive.

Impressively, Audi is also the most successful carmaker in the history of the World Car Awards, winning 11 titles since 2005 and five World Performance Car Awards as of 2022.

A typical car engine has around 200 parts, all of which must be maintained and replaced if they stop functioning correctly. As such, car engine repair is a broad term that covers a wide range of problems.

Signs of potential engine issues include loss of power, illumination of the check engine light, a knocking noise, excessive or discoloured exhaust smoke, overheating and frequent stalling. If an engine fault repair is needed, a mechanic will often conduct a diagnostic test first to determine which component is to blame.

You may be able to diagnose some problems yourself using this guide.

An engine oil leak repair is one of the most common jobs done by mechanics; other repairs might involve the engine management light or engine cooling system. Booking a car engine service from time to time is the best way to prevent problems from developing. Not only does it extend the life of components, it often saves you money in the long term, too.
