Frequently asked questions

Everything you need to know about Audi Approved Used

Can I buy an Approved Used Audi electric car?

Yes, you can. Electric Audi cars aren’t only available from new. Our Approved Used Audi range is refreshed frequently and often includes a variety of all-electric vehicles. These include the Audi Q4 e-tron, Q6 Sportback e-tron and the Audi A6 Avant e-tron – to name just a few.

What does Audi Approved Used mean?

Approved Used isn’t just a tag we add to our used Audi range. For an Audi vehicle to be given Approved Used status, it means that it has passed an intensive inspection with our brand-trained technicians carrying out up to 150 checks.

Every Audi Approved Used vehicle comes with 12 months' warranty and 12 months’ roadside assistance, so you’re supported from day one. Each vehicle also has a verified service history, confirming mileage and previous ownership, and fully electric Audis come with a battery health certificate.

On top of that, you’ll get five days’ complimentary Drive Away Insurance, allowing you to drive your new car home before arranging ongoing cover.

Can I part-exchange my current vehicle for an Approved Used Audi?

Yes. We offer competitive part-exchange deals to make upgrading to your Approved Used Audi simple and convenient.
