Battery boost: how we help
Battery boost for the 2025 Audi A3: the work is done by a shop we trust, never by CarmaCars. A battery that struggles in the cold is often near the end of its life.
About your A3
Bring the owner's manual or service records if you have them. The shop may ask for the VIN to order the right parts. Mention the trim and engine in your request; parts differ between them. Its 2.0L 4-cylinder turbo drives through a 7-speed automatic.
How the arrangement works
The repair is between you and the shop; the rental is with us. We follow up until the shop has the car booked in. The shop quotes the job; you approve it before any work.
Keep moving meanwhile
The rental is priced like any other on our site. Keep moving with a rental while the shop has your car, by the day at our usual rates. We deliver around Toronto; pickup at our location is free.
Talking to the shop
If the car must stay overnight, ask where it will be kept. Ask whether the shop needs your keys, the wheel lock key or the spare. Ask when the car will be ready and how the shop will tell you.
Between shop visits
Have the battery tested before winter if it is more than a few years old. Check that all lights work every few weeks. Keep the spare, the jack and the wheel lock key where you can find them.
Your move
Tell us the job and the car, and a person replies.
Request battery boost
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.
