Arranging the work for the S4
For a diagnostic check on the 2001 Audi S4, a trusted shop does the work and CarmaCars arranges it, with a rental if you need one. A warning light is the car asking for a diagnostic scan; the code tells the shop where to look.
Before the shop sees your S4
If you have the service history of your S4, have it ready for the shop. A photo of the dashboard warning light helps the shop prepare. Tell the shop about any warning light or sound you have noticed. Under the hood: the 2.7L 6-cylinder turbo and all-wheel drive.
What CarmaCars does here
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. Your request goes to a person, who arranges a trusted shop or gives you its name. The shop quotes the job; you approve it before any work.
Stay on the road
The rental is priced like any other on our site. If the repair runs long, keep the rental longer. Collect the car at our location for free, or have it delivered.
What to ask
Ask whether anything else is close to needing attention, and how soon. Ask whether the shop will check anything related while the car is there. Ask if the shop needs the car for a full day or only a few hours.
Small things that help
Keep an emergency kit in the trunk in winter. Listen for new noises and mention them to the shop with as much detail as you can. If the car pulls to one side, ask the shop to check the alignment and the tires.
