Arranging the work for the S4
For battery service on the 2011 Audi S4, 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.
About your S4
Tell the shop the year, the trim and the engine: the 3.0L 6-cylinder supercharged. Say whether the car is drivable; it changes how it gets to the shop. Tell the shop about any warning light or sound you have noticed. Power: the 3.0L 6-cylinder supercharged; drive: all-wheel drive.
The steps
The shop sets the price and the time after seeing the car. You agree the price with the shop before any work starts. We tell you plainly if we do not know a shop for the job.
A car while yours is in the shop
The rental is priced like any other on our site. We collect the rental when your car is back. We meet you with the car at the time we confirm, at your address or ours.
Questions to ask the shop
If a warning light was the reason, ask what the code was and what fixed it. Ask if the shop needs the car for a full day or only a few hours. Ask how the shop takes payment before you pick the car up.
Between shop visits
Check that all lights work every few weeks. Have the cabin air filter changed on the maker's schedule. Keep a record of every service; it helps the shop and adds value when you sell.
Let us know
Send a request: the car, the problem and when suits you.
Request battery boost
Tell us when suits you. A person replies within one business day and arranges it with a trusted shop or recommends one; the shop sets its own price and time.
