Check Engine Light Diagnosis
Your check engine light is on — we come to you with professional OBD-II diagnostic tools to read fault codes, identify the root cause, and give you a clear repair recommendation. No guesswork, no unnecessary shop visits.
Automotive Diagnostics
Professional on-site diagnostics for personal vehicles, fleets, and pre-purchase inspections — anywhere in NYC's five boroughs.
Your check engine light is on — we come to you with professional OBD-II diagnostic tools to read fault codes, identify the root cause, and give you a clear repair recommendation. No guesswork, no unnecessary shop visits.
Scheduled monthly diagnostics for commercial fleets. We come to your lot, scan every vehicle, and deliver a consolidated report with fault codes, maintenance flags, and repair priorities — keeping your fleet on the road.
Buying a used car? We inspect it wherever it's parked — checking for hidden fault codes, electrical issues, and mechanical red flags before you sign anything. Includes a full written report.
Battery, alternator, starter, and charging system issues diagnosed on-site. We identify the root cause of electrical faults — dead batteries, parasitic drains, warning lights — and give you a clear path to repair.
A vehicle in your fleet is showing a fault or warning light? We dispatch to your location — lot, job site, or street — and run a full diagnostic on the spot. No downtime waiting for a shop appointment.
No warning lights yet — but you want to know what's coming. Our preventive scan reads stored and pending fault codes, checks live sensor data, and flags anything that could become a problem before it strands you.
Heading to the DMV for an inspection? We check your vehicle's emissions readiness monitors before you go — so you know if it'll pass, and what needs attention if it won't.
What Customers Say
From Flatbush to the Bronx — here's what vehicle owners across NYC say about having a certified technician come to them.
Check Engine · Brooklyn
"My check engine light had been on for two weeks. Lionel showed up at my apartment in Flatbush within a few hours, ran the full diagnostic, and explained exactly what the code meant. No upsell, no pressure — just a clear answer. That's rare.
Marcus R.
Flatbush, Brooklyn
Bought a used Honda and had Lionel inspect it before I signed. He found two pending codes the seller never mentioned. Saved me from a bad deal.
Danielle F.
Crown Heights, Brooklyn
Fleet of six delivery vans. Lionel comes to our lot every month, scans everything, and sends a report the same day. Downtime is down significantly since we started.
Carlos M.
Sunset Park Fleet, Brooklyn
Electrical · Queens
"Dead battery every morning — I thought it was just old. Lionel found a parasitic drain from a faulty relay I never would have caught. Fixed the root cause instead of just replacing parts. Exactly what I needed.
Priya T.
Jamaica, Queens
I drive for a rideshare app — my car is my income. Lionel came to me at 7am before my shift, cleared a pending code, and I was on the road by 8. That kind of availability doesn't exist at a shop.

Emissions check before my DMV inspection. Passed first try. Lionel told me exactly which monitors were ready and which weren't — no surprises at the station.
