Arranging the work for the A8
Your 2004 Audi A8 needs battery service? We do not do mechanical work, but we arrange it and rent you a car meanwhile. A battery that struggles in the cold is often near the end of its life.
Your car, your notes
Bring the owner's manual or service records if you have them. Tell the shop the year, the trim and the engine: the 4.2L 8-cylinder. The shop sets its own price and time after it sees the car. The 4.2L 8-cylinder does the work, through a 6-speed automatic.
How the arrangement works
You agree the price with the shop before any work starts. The repair is between you and the shop; the rental is with us. We can deliver a rental to you while your car is at the shop.
Keep moving meanwhile
If the repair runs long, keep the rental longer. Add a rental to the same request as the repair. Pick it up from us for free, or have it brought to you.
Questions to ask the shop
Ask whether the quote includes both parts and labour. Ask how long the job should take, so you know how long to rent for. Ask for the work to be listed line by line on the invoice.
Good habits for your car
Keep the fuel tank above a quarter in winter. Have the battery tested before winter if it is more than a few years old. Switch to winter tires before the first snow, and back in spring.
