MOBILE DIAGNOSTICS · ROSELLE, IL

We come to
your driveway.

Car won’t start? Dashboard lit up like a Christmas tree? Don’t pay for a tow until you know what’s wrong. We’ll drive out, scan it, and give you a straight answer — then you decide whether it needs to come into the shop.

WHEN TO CALL US OUT

Don’t guess. Don’t tow blind.

SCENARIO · 01

Car won’t start

Battery? Starter? Fuel pump? Ignition? We’ll find out before you spend on a tow that might not be needed.

SCENARIO · 02

Warning lights you don’t trust

Check engine, ABS, traction control, hybrid system. Read it where it sits instead of nursing it 20 miles to a shop.

SCENARIO · 03

Stranded somewhere local

At work, the grocery store, your kid’s school. We come to the car so you don’t have to wait on a flatbed.

SCENARIO · 04

Second opinion before towing

Another shop quoted big numbers? Have us scan it first so you know what you’re really paying for.

FREQUENTLY ASKED

Mobile diagnostic questions, answered.

How is this different from your shop diagnostic?

The diagnostic work is the same — manufacturer-specific scanners, real techs, plain-English answers. The difference is location: we come to wherever your car is sitting instead of you needing to get it to us. For a check-engine light on a car that’s still driving fine, the shop visit usually makes more sense. For a no-start, a stranded car, or anything you’d otherwise pay a tow truck to move blind, calling us out first saves you money.

What can you actually figure out on-site?

A lot more than you’d think. Battery and charging system tests, full computer code scans with live data, fuel and ignition checks, visual under-hood and under-car inspection, sensor and wiring spot-checks. If the fix is a jumpstart or a tightened terminal, we can sometimes get you rolling right there. If it needs the lift, you’ll know exactly why before you tow it.

How much does it cost?

We quote on the call — it depends on where the car is and what you’re describing. Call us at (630) 894-7077 and we’ll give you a number before we roll out.

How fast can you get there?

Same-day in most cases when you call during shop hours, especially within our core Roselle service area. Next-day if you’re calling late or we’re booked solid.

Do I have to bring the car in afterward?

No. You get the report and you decide. We’d obviously rather fix it for you — but if you want to use the report to get the work done elsewhere, or fix it yourself, that’s your call. The point of mobile diagnostics is information, not pressure.

CAR WON’T START?

Don’t tow blind.
Call first.
