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.

reviewiconMadison, WI
They bored, line-honed, and hot tanked my turbocharged miata's cast iron engine block. They balanced the rotating components, polished the crank, and measured the clearances with new forged internals - Jose is an excellent mechanic. They had about 50 other engine projects in queue and got mine turned around quickly. My engine has ran strong now at wide open throttle for a few thousand miles. I cannot recommend this shop enough, great work at a good price - it is worth the drive from Milwaukee/Chicago

WOW! I can say that this is the best customer service I have ever had! I am a female who knows NOTHING about cars. I was on a cross country roadtrip when I started haveing engine trouble. I got to Madison, WI and needed the car fixed. I was terrified of being taken advantage of. All this was foreign to me as I did not have a car for most of my life. I called around to MANY transmission shops. When I found Midwest Engine Service I knew I was in the right place. From the get go, I was reassured by the kind voice on the phone. I spoke with the owner, Wayne. He went over the issue with my transmission top to bottom. He spoke in laymen's terms, so I actually understood what he was saying. Not only did I feel comfortable trusting Midwest Engine, they gave me the best quote and fastest turn around! Wayne kept me informed step by step, as I was still trying to finish my roadtrip. It seemed I needed a new axle, so I added that to the work order. Again, Waynes' thoughtful words and actions helped keep me at ease. When I got the call that the car was done, the price was even lower than the quote. This included the axle as well! I was so happy with the quality of work, the service and the trusting comfort they gave me. I was able to get back on the road the next morning. Finally, I was leaving Madison. As I was driving out of town that following morning, I got a call from Wayne. I instantly thought he was going to say they needed the car back or something. Why else would they be calling? It was Wayne. He called to make sure the car was running smoothly and that I had made it out of town ok. He then told me he also called to wish me a safe rest of my trip. I felt blessed. I had definitely found the greatest mechanic and team. They are just lovely, honest and have human integrity. Thank you Wayne & the team
