What a scan tells you
The light does not tell you what is going on. We plug in, read the codes, check the electrical side, and give you a fast, accurate answer so you know exactly what your car needs before anything gets replaced.
The codes on the right are standard examples of what a diagnostic reports. A code is where the diagnosis starts. It is not a repair, and it is not a price.

What we do
Each one has its own page with what is included and the signs to look for.
01 / Diagnostics
Check engine light on? We run advanced diagnostics to detect any issue, from engine codes to electrical faults, so you know exactly what your car needs.
02 / Engine
Minor repair or full rebuild. We handle leaks, misfires and power loss and get the engine back to peak performance.
03 / Brakes
Pad replacement, rotor resurfacing and full brake inspections. Your safety comes first.
04 / Battery
From a battery check to a replacement, we make sure your vehicle powers on every time.
How a repair works here
01
You see the price on paper and nothing begins until you have signed it. If the job needs to go past the estimate, we get your OK first.
02
Say so when you drop the car off and the old parts are kept for you to look at or take home.
03
If there is a charge to find the problem, or to keep the car on the lot, you know before you agree to anything.
04
Parts and labor listed line by line, so the invoice matches the estimate you signed.
These four come from the Massachusetts auto repair regulation, 940 CMR 5.05, which applies to every repair shop in the state. We list them because this is how a repair should go, not because they are special.

Questions people ask
If it is steady, get it checked soon; the car is telling you something is off. If it is flashing, that is an active misfire: pull over when it is safe and call us, because driving on it can damage the catalytic converter, which is an expensive part. Either way, a diagnostic tells you exactly what is going on.
Squealing is the early warning. Grinding, a soft or sinking pedal, pulsing in the pedal, pulling to one side or a brake warning light mean come in now. We inspect first and tell you what actually needs replacing.
Most last about three to five years. Slow cranking, dim lights at idle, a battery warning light or needing a jump start are the usual signs. A quick test tells you for sure, and it is worth doing before winter.
Yes. You can call, message and get your explanation in Spanish, and this whole site is in Spanish too.
