The Process
Diagnose first. Then fix.
Throwing parts at a problem is the most expensive way to fix a car. We isolate the actual fault, show you what we found, and quote the real repair — before any work is approved.
- Factory-level diagnostics for European, exotic, domestic, and Asian platforms
- Check engine lights, misfires, hesitation, rough idle, stalling, poor fuel economy
- Electrical: parasitic drains, wiring faults, module and sensor failures
- Oil, coolant, and fluid leak tracing done right the first time
- Second opinions on another shop's diagnosis — bring your paperwork
FAQ
Common questions
My check engine light is flashing — what do I do?
Stop driving and call us. A flashing light usually means an active misfire that can destroy your catalytic converter. A steady light should be scanned soon but isn't an emergency.
Do you charge for diagnostics?
Diagnostic time is quoted upfront. It's the cheapest part of the job — paying to fix the right thing once beats paying to fix the wrong thing twice.
Another shop couldn't figure out my problem. Can you?
That's a big part of what we do. Bring the service history and we'll pick up where they got stuck.
Window tint, XPEL PPF, ceramic coating, wraps, or detailing?
Prestige Car Wash & Auto Detailing handles the cosmetic side — right next door at 482 All Angels Hill Rd, Hopewell Junction · (845) 765-8300. One property, both sides of your car covered.
