About National Auto-Tec
Mobile auto electrical, EV and hybrid diagnostics, module programming and vehicle security across Melbourne. Part of the National Automotive Network Group, alongside National ADAS Calibrations.
The jobs other workshops send away
Most auto electrical work does not need a workshop, it needs the right equipment turning up. We carry manufacturer-level diagnostic and programming tools, plus high voltage gear, to wherever the car is.
15+ years on the tools
Fifteen years of Melbourne vehicles, from pre-CAN wiring to high voltage packs. Long enough that we have seen most faults before, and know which ones the diagnostic code is lying about.
Part of a larger group
We are a National Automotive Network Group company, alongside National ADAS Calibrations. Electrical diagnosis and calibration get booked together instead of chased across two suppliers.
We come to the vehicle
Mobile service across Melbourne's northern and western suburbs and the CBD, with the diagnostic and programming equipment carried in the van rather than waiting at a workshop.
Licensed and insured
Licensed for automotive electrical and air conditioning work, insured, and set up to work safely on electric and hybrid high voltage systems.
National Automotive Network Group
National Auto-Tec is a National Automotive Network Group company. The group brings together specialists who each handle one part of modern vehicle repair properly, rather than one business claiming to cover everything.
Our sister company National ADAS Calibrations handles camera, radar and sensor calibration. Where a job needs both electrical diagnosis and recalibration, which is most post-accident work and anything involving a windscreen, the two can be booked together through one point of contact.
How we work
Diagnose before replacing
A fault code names the circuit, not the culprit. We find what actually failed, which on an older car is often a connector or an earth rather than the module being quoted.
The van is the workshop
Programming tools, scan equipment and high voltage safety gear travel with us, so the work happens in your driveway or at your panel shop.
You get it in writing
Scan reports before and after, a price agreed before we start, and a straight answer when a repair is not worth the money.
Why Choose Us?
15+ years diagnosing and repairing the systems most workshops send away: EV and hybrid high voltage, module programming, airbag and SRS, vehicle security. We are part of the National Automotive Network Group alongside National ADAS Calibrations, and we bring the equipment to your driveway.
