Engine Diagnostics in Elkhart, IN
Check engine light on? We find the real cause, not just the code.
What is engine diagnostics?
A trouble code is a starting point, not an answer. Our diagnostic process uses OEM-level scan tools, live data, and hands-on testing to isolate the root cause before recommending parts. You get an explanation you can understand and a repair plan you can trust.

Frequently Asked Questions
Is it safe to drive with the check engine light on?
If it's steady, usually yes — but get it scanned soon. If it's flashing, pull over and call us. A flashing light means active engine damage.
Will parts stores give me a free scan?
They read codes. We diagnose. A code like P0300 has 20+ possible causes; guessing costs more than diagnosing.
How much does a full diagnostic cost?
$95, and we apply it to any repair over $250 you approve.
Why Michiana drivers choose us for diagnostics
Elkhart, Goshen, Mishawaka, South Bend, and Granger drivers bring their vehicles to Michiana Auto Werks because we treat diagnostics as safety-critical work — not a rushed upsell. Our shop invests in OEM-level scan tools, factory-spec parts, and ongoing ASE training so the repair we quote is the repair your vehicle actually needs. Every job is documented with photos and written notes so you leave with the same understanding a dealer service advisor would give you — without the dealer markup.
We also stand behind the work in writing. Every diagnostics repair is covered by our 24-month, 24,000-mile nationwide warranty, honored at over 17,000 partner shops in North America. If a part we install fails within the warranty window — anywhere — the repair is covered.
Engine Diagnostics cost, lifespan, and what to expect
$95 diagnostic fee (applied to any repair over $250).
Most diagnostics work is same-day. Larger jobs are quoted with a firm pickup time before we start.
24 months / 24,000 miles nationwide on parts and labor — every time.
Waiting on diagnostics work almost always costs more than fixing it early. A worn set of brake pads left too long can score a rotor; a small coolant leak can crack a head; a slipping transmission can turn into a rebuild. If you're seeing any of the warning signs above, book a diagnostic — we'll tell you exactly where you stand.

"Diagnosed my check engine light in 45 minutes when three other shops just kept throwing parts at it. Actually explained what was wrong. Going nowhere else."
"Brought my 2018 Accord in for brakes. They texted me photos of the worn pads before doing anything and the price was exactly what they quoted. Fast, honest, done."
