"Saved me $200 at least. I was ready to drop the car off for 'brake issues' but the AI pointed to a loose caliper bolt. My mechanic confirmed it in 10 minutes — $40 fix."

From "I don’t touch cars" to "I do my own repairs" — tutorials matched to your experience so you only read what’s useful.

Browse all tutorials
Level 1 · Beginner

"I don’t really know how to work on a car."

Understand the noise before going to a mechanic. Simple checks, listening tips, and what to tell the shop so you’re not caught off guard.

Start as a beginner
Level 2 · Comfortable

"I already do small repairs myself."

You change batteries, wipers, or oil. Use the diagnosis to jump to brake checks, suspension inspections, and common sensor or fluid problems.

See "comfortable" guides
Level 3 · Advanced

"I’m used to doing bigger repairs."

You use jack stands and torque wrenches. MyAutoSound confirms your hypothesis, refines possible causes, and links to in-depth technical videos.

Driver guides

Buying a car or visiting a mechanic?

Don’t go in blind. Use these checklists to spot red flags, ask the right questions, and avoid costly surprises.

Buying a used car

Test drive checklist

Spot red flags before you sign anything

Before you go
  • Check the vehicle history report — accidents, flood, odometer rollback
  • Budget for repairs + insurance + registration fees
  • Book a pre-purchase inspection with a trusted mechanic
During the test drive
  • Start cold and listen — knocking, ticking, or rough idle = red flag
  • Brake hard at low speed — grinding or pulling = worn brakes or rotors
  • Turn full lock left + right — clunking = CV joint wear
  • Highway speed — humming or vibration = possible wheel bearing
  • Check that all warning lights go off after engine starts

Heard something suspicious?

Record it right there on your phone. Get an AI diagnosis before you decide — then use it to negotiate the price down, or walk away with confidence.

Record & diagnose now
After you buy
  • Do baseline maintenance right away — oil, filters, fluids
  • Document any noises in the first week — early is easier to diagnose
  • Keep all invoices, contracts, and inspection reports
Mechanic visit

Repair shop checklist

Go in prepared. Never be surprised by the bill.

Before you go
  • Diagnose with MyAutoSound first — know the likely cause before you arrive
  • Note exactly when it happens (speed, temperature, turning, braking…)
  • Ask upfront: "Is there a diagnostic fee, and is it credited toward the repair?"
At the shop
  • Describe it like a story: "when, where, how often, since when"
  • Ask: "Is this urgent, or can I wait a few weeks?" — get a clear priority
  • Get a written estimate before any work starts
  • Ask them to call you before going beyond the approved amount

Share your MAS report with the mechanic

The shareable link includes the likely cause, severity, and a mechanic summary — it saves them time diagnosing and saves you money on labour.

Get your report first
After the repair
  • Compare the final invoice to the written estimate — question any gap
  • Test drive right away to verify the noise is actually gone
  • Keep invoices: they prove warranty and repair history if you resell

Optional next step

Find garages near you once you have a diagnosis.

Use your AI diagnosis to quickly find nearby garages, compare their reviews and choose who to call. You stay in control — MyAutoSound never books or charges anything on your behalf.

  • Filter by "Open now", distance and Google rating.
  • Prioritize garages with "garage" or "atelier" in the name to avoid generic listings.
  • Save your favorites or keep a history of garages you've already checked.

Data powered by Google Places. Availability and accuracy may vary by region. Always verify opening hours and services directly with the garage before going.

FAQ

Frequently asked questions

Everything you need to know before your first diagnosis.

Is the first diagnosis really free?
Yes — every diagnosis that includes the main cause, urgency level, "Can I drive?" verdict, and basic safety checks is completely free. No credit card required. PRO features — the mechanic-ready PDF, repair cost estimate, and full differential causes list — require 1 credit to unlock.
How accurate is the AI diagnosis?
Audio mode reaches ~93% accuracy on common mechanical issues — the AI actually hears your recording and describes the sound acoustically. Text-only mode is slightly lower (~75–80%) since it works from your description alone. Every result includes a confidence indicator and alternative causes so you can judge for yourself. Always confirm safety-critical repairs with a licensed mechanic.
How do I record the noise for the best result?
Get your phone as close to the noise source as safely possible — under the dash for interior noises, near the wheel well for suspension sounds. Record 10–30 seconds while reproducing the exact conditions (speed, turning, braking). Avoid talking over the noise. You can record directly in the tool (no app needed) or upload an existing file (MP3, WAV, M4A, WebM).
Do you store my audio recording?
No. Your audio is encrypted in transit, analyzed by our AI, and deleted immediately after processing. We never store diagnostic recordings. The only exception is if you explicitly choose to contribute a noise to our training dataset — which requires your active consent and earns you a free credit. See our Privacy Policy.
Can I use it when buying a used car?
Absolutely — this is one of the best use cases. During the test drive, record any suspicious noise right from your phone. Get the diagnosis on the spot: if it points to a serious issue (worn brakes, bad wheel bearing, engine knock), you can negotiate the price down or walk away. Many buyers save hundreds by knowing what they're getting into before signing.
What types of noises can it diagnose?
Any mechanical car noise: grinding, squealing, clunking, knocking, humming, rattling, clicking, hissing, whining, or ticking. The AI covers brakes, suspension, steering, engine, transmission, exhaust, AC/heat, and wheel bearings. It works best when the noise is audible and reproducible — intermittent or very faint noises may return lower-confidence results.
What's a credit and how do I get one?
One credit unlocks the full PRO result on one diagnosis — mechanic PDF, cost estimate, detailed causes, red flags, and the shareable report link. Credits never expire. You can earn one free credit by contributing a verified car noise recording to our dataset (upload → review → credit), or purchase credits directly from the results screen. No subscription, ever.
Can I share the diagnosis with my mechanic?
Yes — two ways. PRO results include a shareable link you can text or email directly to your shop (valid for 30 days). Any result can also be exported as a mechanic-ready PDF that summarizes the likely cause, severity, system area, and cost estimate — formatted so your mechanic can read it in seconds.
Does it work for all car brands and models?
Yes — any make, model, or year (gas, diesel, hybrid, electric). The AI uses your vehicle info to refine its reasoning. Older or unusual configurations may produce slightly less specific results, but the general diagnosis is still useful. Electric vehicles have different noise profiles — the AI accounts for this when you enter the vehicle type.
What if the noise changes or gets worse?
Run a new diagnosis — it only takes 30 seconds. Each result is independent, so you can track how the noise evolves over time. If the new result shows a higher severity or a different cause, treat that as a signal the situation is developing and prioritize a mechanic visit. Your diagnosis history is saved in your account.
Why is the server sometimes slow to respond?
The server may take 10–20 seconds to wake up after a period of inactivity (this is normal for cloud hosting). Once it's warm, diagnoses typically complete in 5–15 seconds depending on audio length. The loading screen shows you exactly what stage the AI is on so you're never left wondering what's happening.
Can MyAutoSound replace a mechanic?
No — and it's not designed to. MyAutoSound helps you understand the noise before you arrive, ask the right questions, and avoid being surprised by the quote. Think of it as a second opinion from a knowledgeable friend. For anything safety-critical, always get a physical inspection from a certified mechanic.
