The 2021 Audi A8: Emissions test
The 2021 Audi A8 and an emissions test: CarmaCars arranges a trusted shop, and never does the work itself. Rules on emissions testing differ by province and state.
Your A8 and the shop
Say whether the car is drivable; it changes how it gets to the shop. The shop sets its own price and time after it sees the car. If you have the service history of your A8, have it ready for the shop. The powertrain to know here is the 3.0L 6-cylinder turbo hybrid, with all-wheel drive.
The steps
Your request goes to a person, who arranges a trusted shop or gives you its name. We do not set the shop's price or promise a date. The shop quotes the job; you approve it before any work.
No car? Rent one meanwhile
Rent by the day or the week, and stop when your car is back. If the repair runs long, keep the rental longer. The handover is in person, at your address or at our location.
Good habits for your car
Note the mileage when each service is done, so you know when the next is due. Use the grade of fuel your owner's manual calls for. Have the cabin air filter changed on the maker's schedule.
What to ask
Ask whether the shop will check anything related while the car is there. Ask whether anything else is close to needing attention, and how soon. Ask what warranty the shop gives on its parts and labour.
Next step
Start with a short request; a person replies within one business day.
Request emissions test
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.
