Diagnostic Services in Rochester, MN


In the past, diagnostics were often done with the eyes and a handful of tools. This could take a long time, and wasn’t the most exact way of going about it. Now, On Board Diagnostic tools let mechanics get a readout of exactly what is going on with your engine. At Tilson\\’s Auto Repair Service, we can provide diagnostic services for a wide variety of vehicles, including European and Asian makes.

Experienced Technicians Dedicated to Quality Auto Repairs

Our ASE-Certified Master Technicians are experienced in using a variety of diagnostic services, for Asian, European, and domestic vehicles. These diagnostic services help to detect problems that need to be addressed, such as:

  • Engine Repairs
  • Emissions Repairs
  • Charging System Repairs
  • Cooling System Repairs

Thorough inspections and accurate testing

While our diagnostic services can detect many of the problems your vehicle can be dealing with, we still provide visual inspections of all vehicles. By using multiple methods, we can catch problems that one method may miss.

Comprehensive and Honest Overviews

We use our diagnostic services to provide you with a full overview of what is going on inside your Jaguar, Tesla, smart, or Sprinter. We feel that all service centers should be transparent in their processes, and should provide the car owner the opportunity to talk to the staff and technician, and ask questions. Part of our service to the customer is helping to educate them in the workings of their vehicle, the causes of problems, and the possible repairs and solutions.

No-Pressure Repair Recommendations

Our diagnostic services allow us to provide repair recommendations, breaking them down into the ones that are vital – such as ignition issues or emissions problems – and ones that are merely inconveniences that can be left for another time if needed. This ability to prioritize repairs, coupled with our no-pressure service, is why residents of Sun City and Canyon Gate regularly come back to us when they are in need of service and repair.

Repairs Performed with Quality Parts

Our diagnostic services are specific to each vehicle, and the parts we use in the repairs will be just as specific. Using cheaper, poorly-fitting parts can lead to further repairs down the road, and the small savings now can lead to bigger expenses in the future. We use only the best in OEM and high-quality aftermarket parts, to help with the life of your car.


Always amazing service and very professional. Always get serviced quickly and for a fair price, their shuttle is very convenient if you have to do other things while getting your car fixed. I was recommended by a friend and will definitely be returning and recommending them to friends and family. Keep up the great work guys!!
