Oxford Auto Diagnostics Services

At Oxford Auto Diagnostics, I offer accurate, honest, and technician-led diagnostic services from a fully equipped home setup in Oxford. Whether you're dealing with persistent warning lights, electrical faults, or intermittent issues that others have failed to fix. I provide clear answers, not guesses.

Based in Bartholomew Road, Oxford.

When Should You Get a Diagnostic Check?

Your car's electrical system is a complex and interconnected network, powering everything from the engine control unit to sensors, brakes, lighting, and even your infotainment system. When something goes wrong, it often won’t be visible from the outside. That’s where specialist diagnostic equipment comes in.

With a scan, a trained technician can access your vehicle’s internal data, communicate with control modules, and identify the exact source of a fault—far beyond what a basic code reader can do.

Full System Diagnostic Scan

A comprehensive scan of all available control modules using advanced tools like Autel or Snap-On. This includes:

  • DPF Solution

  • Fault Detecting

  • ECU Coding

  • EGR Solution

  • AdBlue Solutions

  • Remap Stages1/2/3

  • Vehicle Oil Services

  • Engine Control Unit (ECU)

  • ABS / Traction Control

  • Airbags (SRS)

  • Body Control Module (BCM)

DSG Gearbox Optimisation

Unlock the full potential of your transmission with smarter shifts and smoother performance.

  • ✅ Enhanced Fuel Efficiency – Optimised shifts reduce unnecessary fuel burn

  • ⚡ Quicker Gear Changes – Smoother, faster transitions for better driving dynamics

  • 🛡️ Extended Clutch Life – Reduced wear through smarter engagement logic

  • 🚀 Boosted Performance – Sharper response and power delivery when you need it

  • 🔧 Improved Torque Management – Better control under load, uphill, or towing

Battery, Starter & Charging System Checks

For non-starting cars or battery-related issues, I offer:

  • Battery health check (voltage/load test)

  • Alternator performance scan

  • Starter motor draw test

  • Basic parasitic drain checks

📉 I’ll help you determine if you need a new battery or if there’s an underlying issue.

Check Engine Light Diagnosis

That amber engine light? It could be minor—or major. I’ll decode it and explain it clearly.

  • OBD-II scan + live sensor readings

  • Common issues: sensors, EGR, misfires, evap leaks

  • Light reset (only if fault is safe/cleared)

💡 You’ll understand what the fault means and whether it needs urgent repair.

Electrical Fault Tracing

Strange behaviour like windows not working, dash lights flickering, or sensors going haywire?

  • Fuse & relay checks

  • Continuity and voltage drop testing

  • Module communication check

  • Wiring loom inspection (visual & tool-based)

🔍 Best suited for those “I’ve tried everything” scenarios.

ABS & Brake System Diagnostics

Braking issues aren’t something to ignore. This service includes:

  • Real-time wheel speed sensor testing

  • ABS module scan

  • Stability control & traction diagnostics

  • Wiring and brake switch checks

🛞 Especially useful when ABS/traction warning lights appear intermittently.

No problem — I offer a quick consultation to help you figure it out:

  • Discuss your car’s symptoms

  • Recommend whether a full diagnostic is needed

  • Suggest the next steps, even if I’m not the one doing the repair
