Car diagnostics: how we help
For a diagnostic check on the 1998 Audi A4, CarmaCars arranges a trusted shop and rents you a car while yours is in. A warning light is the car asking for a diagnostic scan; the code tells the shop where to look.
Before the shop sees your A4
The shop may ask for the VIN to order the right parts. Say whether the car is drivable; it changes how it gets to the shop. Tell the shop about any warning light or sound you have noticed. It is powered by the 1.8L 4-cylinder turbo, with front-wheel drive.
The steps
You agree the price with the shop before any work starts. We can deliver a rental to you while your car is at the shop. We follow up until the shop has the car booked in.
Stay on the road
Keep moving with a rental while the shop has your car, by the day at our usual rates. Rent by the day while the shop has your car. Delivery and pickup are both options across the Toronto area.
Between shop visits
Check the tire pressure once a month, when the tires are cold. Look at the tire tread before long trips. Keep the fuel tank above a quarter in winter.
Getting a clear quote
Ask how the shop takes payment before you pick the car up. Ask if the shop needs the car for a full day or only a few hours. Ask whether the quote includes both parts and labour.
Questions first?
Describe the problem, and we arrange a trusted shop.

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.
