Arranging the work for the S8
For battery service on the 2015 Audi S8, CarmaCars arranges a trusted shop and rents you a car while yours is in. Lights left on overnight are the classic reason for a flat battery.
Details the shop needs
The shop sets its own price and time after it sees the car. Tell the shop about any warning light or sound you have noticed. A photo of the dashboard warning light helps the shop prepare. Under the hood: the 4.0L 8-cylinder turbo and all-wheel drive.
Who does what
You approve the shop's quote before any work. You agree everything with the shop before work begins. We pass your request to a trusted shop or give you its name.
A car meanwhile
The rental is priced like any other on our site. Pick a car that suits your week from our fleet. Your offer shows any delivery fee before you pay.
Before the shop starts
Ask what warranty the shop gives on its parts and labour. Ask whether the parts are new, rebuilt or used. Ask whether the shop will check anything related while the car is there.
Small things that help
Have the battery tested before winter if it is more than a few years old. Switch to winter tires before the first snow, and back in spring. Check that all lights work every few weeks.
Over to you
