What to Expect When You Book

You'll bring your vehicle to our shop where we connect advanced scan tools directly to your engine's onboard computer. This process reads stored trouble codes, live sensor data, and freeze frame information that tells us exactly when and how the issue occurred. Our technicians review these readings in real time, cross-referencing them with manufacturer specifications to confirm the root cause.


Lonewolf Diesel follows a systematic approach that checks fuel delivery, ignition timing, air intake, and exhaust system performance. Dealer-level scan tools allow us to see data that generic code readers miss. We test every component related to the trouble code before recommending repairs, ensuring you only pay for what's actually needed.


After diagnostics, you receive a detailed explanation of findings, including which sensors or systems triggered the warning and what repair options are available. We walk you through the severity of each issue, helping you prioritize what needs immediate attention versus what can wait. This transparency ensures you make informed decisions about your vehicle's care.
