How it works

- Add your trouble codes (optional)If the check engine light is on, pair any Bluetooth OBD-II scanner with the Android app to read the codes yourself, or look a code up if the shop gave you one.
- Get a plain-English second takeAthrun explains what the part does, whether the repair matches the symptoms, what else could cause them, and a typical price range.
- Go back to the shop informedApprove it with confidence, ask the shop to show you the problem, or find another shop nearby for a hands-on look.
What a second opinion looks like
Example
- A slow downstream oxygen sensor (often $150–$400)
- An exhaust leak near the sensors ($100–$500)
Illustrative example. Real answers depend on your car and what you share. Price ranges are rough US shop prices.
Questions worth asking any shop
A good shop will be glad to answer these. They help you understand what you're paying for, whatever you decide.
- Can you show me? Ask to see the worn part, the leak, or the measurement (brake pad thickness, rotor wear, a scan tool reading).
- What did the scan show? If a warning light is on, ask for the exact trouble codes, not just the conclusion.
- Does this need to be done today? Ask what happens if it waits a month, and what's a safety issue versus maintenance.
- Can I get it itemized? Parts and labor separately, with the labor hours.
- Which parts are you using? Original-equipment or aftermarket, and the warranty on parts and labor.
- Can I have the old parts back? A simple way to see what was replaced.
Repairs people often ask about
These are some of the recommendations that most often lead people to want a second opinion. Many are completely legitimate. They're just worth understanding before you approve them.
| Recommendation | What to check |
|---|---|
| Rotors with every brake job | Rotors can sometimes be reused if they're above the minimum thickness and not warped. Ask for the measurement. |
| Fluid flushes | Compare against your owner's manual schedule. Transmission, coolant and brake fluid intervals vary a lot by vehicle. |
| Catalytic converter for P0420 | Oxygen sensors and exhaust leaks can set the same code. See the P0420 guide. |
| Air and cabin filters | Ask to see the old filter. Many are easy to check or replace yourself. |
| Timing belt | Check whether your engine has a belt or a chain, and the replacement interval in the manual. |

Common questions
Is Athrun free?
Yes. The Android app and the web version at driveathrun.com are free to use.
Does Athrun replace a mechanic?
No. Athrun is an AI assistant. It can't see or touch your car, so a hands-on inspection is still the final word. What it can do is explain what a repair is for, whether it fits the symptoms, and what it usually costs, so you can ask the shop informed questions.
Do I need an OBD-II scanner?
No. You can describe the problem and the quote in your own words. If you have a Bluetooth OBD-II scanner, the Android app can read your car's trouble codes directly, which gives a more specific answer.
Is there an iPhone app?
Not yet. iPhone users can use the full chat in the browser at driveathrun.com.
