Battery boost: how we help
CarmaCars does not do mechanical work, but for battery service on the 2015 Audi S6 we arrange a trusted shop. A battery that struggles in the cold is often near the end of its life.
About your S6
Your owner's manual lists the maintenance schedule for the S6. If you have the service history of your S6, have it ready for the shop. Say whether the car is drivable; it changes how it gets to the shop. The engine is the 4.0L 8-cylinder turbo, with all-wheel drive and a 7-speed automatic.
How the arrangement works
We keep you posted until the car is booked in. Send a request with the car and what it needs; a person replies within one business day and arranges it with a trusted shop or recommends one. We can deliver a rental to you while your car is at the shop.
A rental while you wait
The rental is priced like any other on our site. Pick a car that suits your week from our fleet. The handover is in person, at your address or at our location.
Between shop visits
Keep the spare, the jack and the wheel lock key where you can find them. Keep the fuel tank above a quarter in winter. Check that all lights work every few weeks.
Questions to ask the shop
Ask when the car will be ready and how the shop will tell you. Ask how the shop takes payment before you pick the car up. Keep the invoice; it is part of the car's service history.
Make a request
Send the car's details and the job, and we take the next step.
