Check engine light diagnostics where the car sits.

A warning light tells you something is wrong, not what. We come to you, scan the vehicle and test until we find the actual cause, so you don't pay for parts you don't need.

What's included

What a diagnostic visit includes

A trouble code points to a system, not a part. The same code can come from a bad sensor, a wiring fault or a vacuum leak, so reading the code is only the first step.

Once we know the cause, we explain it in plain terms and give you a quote for the repair. You decide what happens next.

  • Stored trouble codes read with a scan tool
  • The related parts and systems tested to find the real cause
  • A plain-English explanation of what we found
  • An upfront quote for the repair
  • A diagnostic fee that can be credited toward the repair you approve

When to book

When to book a diagnostic visit

A steady check engine light

It's usually safe to drive for now, but get it looked at soon. Small problems get more expensive when they're left.

A flashing check engine light

This usually means the engine is misfiring badly enough to damage the catalytic converter. Avoid driving it, and call or text us.

It won't start

A no-start can be the battery, the starter, the fuel system or something else. We test before replacing anything.

A new noise, smell or vibration

Tell us when it happens and what it sounds like. Videos help, and you can text them to us.

Another warning light

ABS, battery, temperature and other lights each point to a different system. Tell us which one is on.

It just doesn't drive right

Stalling, hesitation, poor mileage and rough shifting are all worth checking, even without a light.

Some problems need longer testing, taking components apart or specialized equipment. If yours does, we'll tell you before going any further.

How it works

Three steps. No drop-off, no waiting room.

01

Tell us what's going on

Your vehicle, the problem and where it's parked. Book online, call or text. You can text us photos of warning lights, too.

02

Get a clear quote

If we can price it accurately, you get an upfront quote. If it needs a look first, we book a diagnostic visit instead of guessing.

03

We come to you

We show up at the scheduled time and do the work right where your vehicle is parked, at home or at work, so you can get on with your day.

Pricing

Clear pricing. No surprises.

Every vehicle is different, so we quote each job for yours instead of posting flat prices. You'll know what you're paying, and when, before we pick up a wrench.

What you can count on

  • An upfront quote for your exact vehicle before any work starts
  • Parts and labor listed separately on every quote
  • No travel fees and no convenience fees
  • Nothing extra replaced without your OK
  • A 12-month / 12,000-mile warranty on our workmanship

When you pay

Routine maintenance
After the work is done.
Diagnostic visits
At the visit. The fee can be credited toward the repair you approve.
Larger repairs
A parts deposit before we order, with the balance due when the job's complete.

Excellent service and experience! Upshift provided a very efficient and professional experience. They showed up on time, performed outstanding work, and best of all, saved me hours of sitting in a waiting area. I never had to leave home!

Brilliant! Being able to have car service performed at MY convenient location is just wonderful! I imagine that many of us have had to drop our cars off, figure out rides or sit for HOURS waiting for our car service to be done (I have...). Not so with UPSHIFT! They'll come to my house, or my office, or... wherever is convenient, and do the work while I continue doing what I need to or want to do. No more hours wasted sitting in a waiting room. No more trying to figure out how to get a ride...

Great service and smooth arrangements, payments, messaging for reminders and other contacts, and excellent web presence. I'll definitely call on them again for further remote maintenance.

Super easy and convenient to book. It’s so nice to not have to sit in a mechanic shop and to get car maintenance done from the comfort of my own home!

Diagnostics: common questions

Still unsure? Call or text (518) 888-7497 and a real person will answer.

Why is there a fee for diagnostics?

Finding the real cause takes tools and expertise, and it keeps you from paying for parts you don't need. When you approve the repair, the fee can be credited toward it.

Do I still pay if I don't go ahead with the repair?

Yes. The fee covers the time and equipment it takes to find the problem, whether or not you have us fix it.

Is it safe to keep driving with the light on?

If the light is steady and the car drives normally, it's usually fine for a short while, but book a visit soon. If the light is flashing, or the car is running rough or overheating, stop driving it and call or text us.

Can you fix it in the same visit?

It depends on the repair and whether the part is on hand. Once we know what's wrong, we'll tell you what it needs and when we can do it.
