Arranging the work for the A6
Need a diagnostic check for the 2004 Audi A6? We arrange it with a trusted shop; the work is never done by CarmaCars. A warning light is the car asking for a diagnostic scan; the code tells the shop where to look.
About your A6
The shop may ask for the VIN to order the right parts. Note the mileage on the odometer when you send the request. Tell the shop the year, the trim and the engine: the 3.0L 6-cylinder. It uses the 3.0L 6-cylinder and front-wheel drive.
The steps
Tell us when suits you, and whether the car can be driven. You approve the shop's quote before any work. We can deliver a rental to you while your car is at the shop.
Keep moving meanwhile
Rent for as long as the job takes, by the day or the week. Keep the rental as long as the repair takes. Collect the car at our location for free, or have it delivered.
Car care, briefly
Keep a record of every service; it helps the shop and adds value when you sell. Follow the maintenance schedule in your owner's manual, by time or distance. If the car pulls to one side, ask the shop to check the alignment and the tires.
What to ask
Ask whether anything else is close to needing attention, and how soon. If a warning light was the reason, ask what the code was and what fixed it. If you want to see the old parts, ask for them back.
Make a request
Need the work and a rental? One request covers both.
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.
