Auto Diagnostic FAQs
How do vehicle diagnostic systems work?
OBD stands for On-Board Diagnostics and is a sophisticated computer that collects vital information from a network of sensors, monitoring engine performance, emissions, and other key functions. It not only regulates various car systems but also acts as a diagnostic tool, alerting you to potential problems before they become major issues.
How long does a car diagnostic last?
While a basic diagnostic test typically wraps up in 1-1.5 hours, complex issues demanding further examination and component access/testing can extend the process to 2-3 hours. The length ultimately depends on the severity of the problem and the potential presence of multiple underlying culprits.
What is included in a car diagnostic test?
Diagnostic tests are like X-rays for your vehicle, utilizing specialized equipment to scan its complex systems and components like the engine, transmission, and throttle. From minor oil tank issues to intricate electrical glitches, these tests diagnose a wide range of potential problems. However, interpreting the data they generate requires trained professionals, making dealer shops and skilled mechanics your best bet for accurate diagnoses.

OUR REVIEWS


Barbro Andren , 05/29/2025I was in Lake Mills this morning running an errand. I live in Cambridge (which by the way it’s not on your drop-down list. It’s only about 10 miles away so definitely worth the drive.) Anyway I was driving through town and my tire light went on. I pulled into a gas station and their tire gauge was broken, but the guy there said to me “See that building over there?” I said yes, and he said “Go over there. They’ll help you. He’s a really nice guy.” So I drove over to the back of the building, (Steve’s) and I ran into a really nice guy (Steve) working on a car at the back of the shop. I asked if he could help me, and he said sure, just go have a seat upfront, and indicated he’d take a look at it as soon as he could. They were crazy busy. I’ll be here for awhile, I thought. I went up front and explain my dilemma to Cassy in the front office. I was planning to leave at 7 o’clock tomorrow morning to drive to St. Louis, but when Steve, within minutes, showed me the size of the hole in my tire. I knew that was not going to happen. I have a Volkswagen Tiguan, four-wheel-drive, and tires are not easily found. But Cassie was on it and located some that could be delivered and put on the next morning. Meanwhile, Steve put my spare limper tire on, and all the while I was talking back-and-forth with a service guy at my car dealer in Madison. I learned my tires were under warranty and that my roadside assistance would take care of it (whew) but only if the work was done by them in Madison. I asked Cassy what I owed them, and was tempted to pay them double just to make myself feel better. It was beyond reasonable. I thanked Steve and Cassie profusely and actually felt bad that a warranty thing couldn’t be covered there. (But not sorry to save big bucks.) Meanwhile, another customer had been telling me how she’s been going there for 37 years, and that she couldn’t imagine going anywhere else. No kidding. If your car needs literally anything done to it, run don’t walk, to Steve’s. It’s one of those places that’s just like America used to be. Although all they did was change my tire, they absolutely made my day, and kind of restored my faith in humanity a little bit. Yay, Steve’s! Thank you!
