Built for modern
vehicles.
John Wire Auto Garage is a Nyeri-based workshop specialising in advanced car-electrical work and OBD2 diagnostics — supported by a complete mechanical, panel-beating and paint operation.
Diagnose first.
Fix once.
Modern cars don't reward guesswork. Our team uses proper OBD2 scanners, live data analysis and wiring schematics to find the real cause of a fault — not just the symptom. That means cleaner repairs, fewer return visits and an honest invoice at the end.
From a check-engine light on a daily-driver to accident repair on a high-end saloon, we treat every vehicle with the same standard of workmanship.
Diagnostic-led
Decisions backed by live ECU data — not assumptions.
Reliable
Honest pricing and quality parts. We stand behind every repair.
Skilled craftsmanship
Auto-electrical, mechanical, panel and paint — all in-house.
Customer-first
Clear updates, transparent quotes, no surprises.
All brands
Petrol, diesel and hybrid across Japanese, German and European makes.
On schedule
We respect your time and return your vehicle when promised.
Ready when you are.
Stop by the workshop or book in advance — we'll get your vehicle in, diagnosed and back to you.
