Not Sure What's Wrong?

Something Isn't Right? We'll Find Out Why.

Is your vehicle making a strange noise, running differently, showing a warning light, losing power, or simply not operating the way it should?

You don't have to know what's wrong before calling us.

At Zavagli Auto LLC, we specialize in diagnosing problems when the cause isn't immediately obvious. Whether it's an electrical issue, mechanical problem, intermittent failure, drivability concern, or multiple warning lights, our job is to find the cause — not just replace parts and hope it fixes the problem.

We Diagnose. We Test. We Find the Cause.

Modern vehicles can have complicated systems where one problem can create multiple symptoms.

A warning light doesn't always tell you which component actually failed. A vehicle that won't start doesn't necessarily have a bad starter. A low-pressure code doesn't automatically mean the fuel pump is the problem.

That's why we use a combination of:

• Professional diagnostic scan tools

• Electrical testing

• Voltage and resistance testing

• Circuit testing

• Mechanical testing

• System testing

• Visual inspection

• Manufacturer diagnostic procedures

• Live data analysis

• Component testing

• Road testing when appropriate

Our goal is to determine what is actually causing the problem before recommending repairs.

Intermittent Problems

Some of the hardest problems to diagnose are the ones that come and go.

If your vehicle works normally when you bring it in but the problem keeps returning, we can help determine what systems need to be tested and what conditions may be causing the failure.

We Work on More Than Just Basic Repairs

Some diagnostic problems require more than simply pulling trouble codes.

Zavagli Auto LLC works with:

Cars • Trucks • Diesels • Light-Duty • Medium-Duty • Modern Computer-Controlled Vehicles

We can diagnose problems ranging from basic charging and starting issues to complicated electrical, fuel, engine, drivetrain, and communication faults.

Don't Just Replace Parts Until It Works

Replacing parts based only on a symptom or trouble code can become expensive quickly.

Our approach is to test the system and verify the failure whenever possible before recommending parts.

A diagnostic code can point us toward a system or circuit, but further testing may be necessary to determine what actually caused the fault.

Our Goal:

Find the problem. Explain the problem. Recommend the repair.

When Other Shops Can't Find It

If you've already had a vehicle looked at and the problem still hasn't been solved, bring us the information you have.

Previous diagnostic results, codes, repair attempts, and symptoms can help us understand what has already been tested and where to continue looking.

We can work through complicated problems that may require a more detailed diagnostic approach.

Mobile & Shop Diagnostics

Many diagnostic services can be performed mobile, allowing us to come to your vehicle.

Some problems, however, require equipment, testing conditions, access, or repairs that can only be performed properly at our shop.

If your vehicle needs to come to the shop for further testing, we'll explain why.

Not Sure What Service You Need?

That's okay.

You don't need to diagnose your own vehicle before contacting us.

Tell us:

• What the vehicle is doing

• When the problem started

• What warning lights are showing

• Any noises or symptoms you've noticed

• Whether the problem happens all the time or intermittently

• Any recent repairs or modifications

• Any diagnostic codes you've already received

We'll determine what diagnostic approach makes sense from there.
