Mobile Car Diagnostics in New Braunfels, TX
Owner-operated, done on site across Seguin and Guadalupe County - we come to you. Hablamos Español.
A check engine light or a flickering accessory is a symptom, not a verdict. Vic comes to your driveway or job site and traces the actual cause - across all makes and models, residential and commercial - within about 50 miles of New Braunfels, Texas.
A scan tool pulls a code; testing finds the real fault. A sensor code can mean a bad sensor, or it can mean a wiring or ground problem setting the sensor off. Vic tests before any part is thrown at the problem.
What You’ll Notice
Check Engine Light
Steady or flashing - a stored code, but the code names a circuit, not always the failed part.
Flickering Lights
Lights that dim or flicker point to a charging or ground fault, not just a bulb.
Dead Accessories
Power windows, locks, or the radio that stop working point to a circuit or module fault.
Intermittent No-Start
Starts fine one day, nothing the next - often a relay, ground, or security circuit.
Battery Drain
The battery goes dead overnight from a parasitic draw that needs to be traced circuit by circuit.

Can It Be Done In Your Driveway?
Most mobile car diagnostics in new braunfels, tx jobs are completed on site. Here’s what Vic needs to work safely where the vehicle sits.
- No tow for a vehicle that runs but throws a light.
- The fault is tested in your driveway, where it actually happens, not on a shop bench.
- No waiting room while a service writer relays updates.
- You talk to Vic directly about exactly what the data showed.
Some faults only show up under specific conditions - heat, vibration, a cold start. Vic tells you plainly when a problem needs a few real-world drive cycles to surface rather than a single sit-down test.
