Compare Audi A4 turbo fault repair or replacement quotes from specialist garages

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. Find out whether Audis are expensive to repair in this guide or take a look at how their maintenance costs compare with SEAT and Skoda.

Turbochargers, usually called turbos, are designed to give your car extra power. They are only activated at certain speeds and work by forcing more air into the engine, increasing the strength of the combustion. You can read more about how turbochargers work here.

Common signs of turbo failure include a loss of power, difficulty maintaining high speeds, slower acceleration, grey/blue exhaust smoke, and a dashboard warning light. If your car shows any of these symptoms, you may need to book a turbo repair.

In some cases, a repair may not be possible, in which case a turbo replacement is required. Turbo reconditioning or turbo refurbishment is a restorative process that gives older turbos a new lease of life. If you need to replace your turbo, opting for a refurbished rather than a brand-new one is usually cheaper. Consult a turbo specialist for advice about the best option for your car.
