Arranging the work for the S8
The 2015 Audi S8 and a diagnostic check: CarmaCars arranges a trusted shop, and never does the work itself. A steady check engine light needs a check soon; a flashing one means pull over safely and get help.
Your car, your notes
Tell the shop about any warning light or sound you have noticed. Bring the owner's manual or service records if you have them. Tell the shop the year, the trim and the engine: the 4.0L 8-cylinder turbo. It uses the 4.0L 8-cylinder turbo and all-wheel drive.
What we arrange
The repair is between you and the shop; the rental is with us. Tell us when suits you, and whether the car can be driven. We tell you plainly if we do not know a shop for the job.
Driving while yours is at the shop
If the repair runs long, keep the rental longer. We deliver the rental to you and collect it when your car is ready. Delivery starts at $0 plus distance; collecting the car yourself is free.
Good habits for your car
If the car pulls to one side, ask the shop to check the alignment and the tires. Switch to winter tires before the first snow, and back in spring. Follow the maintenance schedule in your owner's manual, by time or distance.
Getting a clear quote
Ask whether the shop needs your keys, the wheel lock key or the spare. Ask how the shop will contact you if it finds something unexpected. If a warning light was the reason, ask what the code was and what fixed it.
When you know your dates
A short request starts it: the car, the problem, and when suits you.
Request car diagnostics
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.
