Electrical & Diagnostics
We find what other shops miss.
Modern vehicles run on dozens of computers and miles of wiring. When a warning light comes on or a gremlin appears, our technicians use dealer-level scan tools and proven diagnostic process to pinpoint the real cause — not just guess at parts. For deeper reads, see when ECU programming is needed and how to check EV battery health.
Straightforward, upfront pricing
Final price depends on your vehicle and parts — we always quote before any work starts. Financing available on repair jobs.

Good to know
My check-engine light is on — is it safe to drive?
A steady light usually means it’s safe to drive in to us; a flashing light means stop driving and call us right away.
Can you diagnose intermittent problems?
Yes. Intermittent electrical faults are our specialty — we have the tools and patience to track them down.
How does your diagnostic process work?
We start with a full system scan, then test the actual circuits and components rather than just swapping parts at the code. You get the real root cause and an upfront quote.
Why does the dealer charge so much more for diagnostics?
We use dealer-level scan tools without dealership overhead, so you get the same depth of diagnosis — usually for less — and we explain exactly what we found.
My warning light went off on its own — do I still need it checked?
It’s worth checking. Many faults are intermittent and the stored codes remain, so we can often still pinpoint the issue before it comes back worse.

Audi R8 V8, Towed In After Three Shops: Recovering Two Silent ECUs and Restoring the Factory Setup
A first-generation Audi R8 4.2 V8 arrived on a flatbed, not starting. It had been ECU-tuned, the owner wanted it back to factory, and three shops had already tried. Their attempts had corrupted the car’s configuration: both engine ECUs no longer communicated and the immobilizer would not let the engine start. We recovered both ECUs, reprogrammed the immobilizer and restored the original factory configuration.
