Like going to the doctor’s office or visiting a clinician, you can use auto diagnostics to identify problems with your vehicle. A proper diagnosis allows you to make informed decisions about repairs without having to “guesstimate” the costs, timeframe, or extensiveness.

Our Diagnostic Services

Getting a diagnostic test done on your vehicle doesn’t have to be complicated. With Lonsdale Auto Works, the process is quick, simple, extremely accurate, and accomplished with the latest technology on the market.

Here is a list of vehicle systems and components which we can diagnose: 

Check Engine Light Diagnosis

The check engine light is found on your dashboard. When it comes on, that means your vehicle’s onboard computer system has detected a problem with one or more engine or emissions system components.

The reasons are varied, although not all warnings are serious. However, others could lead to more severe problems, meaning immediate repair is highly recommended. 

Some things which our diagnostic services can discover include problems with the following:

Bring your vehicle in for a diagnostic from Lonsdale Auto Works today. Our team would happily accommodate your schedule and diagnose and fix whatever is causing your check engine light to turn on.

Solving The Check Engine Light Mystery With Reliable Equipment

Lonsdale Auto Works relies on cutting-edge equipment to diagnose domestic and imported vehicles. Today, we’re proud to own two incredible pieces of software: 

  • Autel Scanner: This powerful tool can quickly diagnose automotive faults and fix software-controlled emissions and drivability problems.
  • Snap-on Diagnostics: As one of the most respected brands in vehicle diagnostics, Snap-on allows us to instantly uncover issues and propose suitable solutions.

Benefits of Getting Vehicle Diagnostics

The benefits of vehicle diagnostics genuinely speak for themselves. Not only can it identify the reason for a check engine light. It could save you thousands of dollars in unnecessary repairs.

For example:

  • Precautionary diagnostics can catch issues with your vehicle before they get worse. You could stop a tiny tear from becoming a severe setback. Since many cases will set off your check engine light once they’ve reached critical mass, you’ll be doing yourself (and your wallet) a favor.
  • Regular diagnostics increase the speed, quality, and performance of your vehicle. An ounce of prevention is worth a pound of cure, and you can reap the reward for yourself every time you hit the road.
  • Diagnostics can help you determine whether your car is worth repairing or not. If your vehicle is worth less after all the repairs, it may be time to purchase a new car.
