Car diagnostics: how we help
Your 2018 Audi A6 needs a diagnostic check? We do not do mechanical work, but we arrange it and rent you a car meanwhile. A warning light is the car asking for a diagnostic scan; the code tells the shop where to look.
Your car, your notes
Note the mileage on the odometer when you send the request. 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. It is powered by the 2.0L 4-cylinder turbo, with front-wheel drive.
Who does what
The shop sets the price and the time after seeing the car. You agree the price with the shop before any work starts. Your request goes to a person, who arranges a trusted shop or gives you its name.
Keep moving meanwhile
A rental from us keeps you moving while the shop has your car. We can have a rental ready the day your car goes in. Delivery starts at $0 plus distance; collecting the car yourself is free.
Getting a clear quote
If the car must stay overnight, ask where it will be kept. Ask the shop to call you before doing anything not on the estimate. Keep the invoice; it is part of the car's service history.
Good habits for your car
Switch to winter tires before the first snow, and back in spring. Top up the washer fluid with a winter mix in the cold months. Check that all lights work every few weeks.
Send a request
Tell us what is wrong with the car, and we arrange the rest with a trusted shop.
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.
