The Problem the Dealer Couldn't Figure Out.
Modern cars are rolling computers — dozens of modules, hundreds of sensors, networks talking to each other. When something glitches, most shops swap parts until it goes away. Rudy reads the data, traces the fault, and finds the actual failure. He's the mechanic your mechanic can't figure out.

Common Questions
Frequently Asked Questions
My dealer couldn't find the problem. Can you?
Often, yes. Dealers are trained to follow a flowchart and replace parts by procedure. Rudy diagnoses from data and decades of experience, which is exactly what intermittent and unusual electronic faults require. Bring it in and we'll take a real look.
What's the difference between this and a check engine light scan?
A check engine light scan reads engine and emissions codes. Full computer diagnostics covers every module in the car — ABS, airbags, body control, transmission, networks — and digs into electrical faults that don't always throw a simple code. It's the deeper level of diagnosis.
Do you work on both new and older vehicles?
Yes. Rudy works on everything from the latest computer-controlled vehicles to classics with no computer at all. The diagnostic approach changes with the car — and he's fluent in both.
Will you tell me what's wrong before charging me to fix it?
Always. We diagnose, explain the problem in plain language, and quote the repair before doing any work. No surprises and no pressure.
