Vehicle Diagnostics in Lagos
Computer‑based diagnostics and structured troubleshooting for warning lights, drivability issues, and intermittent faults.
A warning light is a clue—not a complete answer. Our diagnostic process combines scan data with physical testing so you get a repair plan grounded in evidence, not guess‑and‑swap parts.
Intermittent faults are common in modern vehicles. We document conditions, freeze‑frame data (where available), and likely failure modes so you can decide what to fix now vs monitor.
What drives your quote
Final costs depend on inspection findings, parts tier, and your approved scope — never a one-size menu price from a web page.
- Fees reflect time on the vehicle, tooling, and complexity — simple checks differ from deep electrical hunts.
- Intermittent faults often need structured retests; we set expectations before you commit to extended diagnosis.
- Repair quotes are separated from diagnostic time where it keeps the invoice understandable.
Turnaround times
- Initial assessment commonly takes 1–3 hours depending on complexity and queue.
- Intermittent faults may require an overnight hold or a return visit— we set expectations before you commit.
Warranty, parts & quality policy
- Diagnostic fees cover time and expertise; they do not guarantee a single root cause on the first visit for intermittent issues.
- Repairs carry parts/labour warranty terms quoted on approval—evidence-based parts only.
- If a dealer-only calibration is required, we’ll tell you early rather than charging exploratory labour blindly.
Our process from booking to handover
A consistent workflow reduces mistakes, speeds approvals, and keeps you informed at every step.
- 1
Symptom capture
We reproduce the issue where possible and record conditions: cold/hot, idle/load, gear selection.
- 2
Scan & baseline
Codes are interpreted in context—not “replace the sensor” because it logged a fault.
- 3
Directed testing
We use wiring tests, fuel/ignition checks, smoke/vacuum approaches only when justified.
- 4
Estimate & approval
You get a clear quote for the next repair step before major component replacement.
- 5
Verification
After repairs, we confirm monitors, codes, and drivability where safe and practical.
What's included in this service
- Code retrieval with context (history, pending, permanent codes where relevant)
- Live data review for fuel trims, misfires, temperatures, charging, and key sensors
- Targeted component tests aligned to likely failure modes
- Written findings with a prioritized repair path and cost bands
- Clear guidance on what happens if you defer a repair (risk/symptoms)
- Re-test after repairs to verify fixes when appropriate

What clients say
Stories below mirror the testimonials carousel on the homepage—swap in verified quotes and headshots when your team provides them.
“I have tried three other auto shops on the Island and none of them came close to HIQ. The diagnostics were thorough, the pricing was transparent, and they finished two hours ahead of schedule. The value has been worth every naira.”
“The app is intuitive, the team responds instantly, and the quality of work is genuinely world-class. I book, they pick up my car, and return it perfect. Nothing like this existed in Lagos before HIQ. They have completely changed the game.”
Frequently asked questions
Will you clear my check engine light?
We may clear codes after repairs or to verify a fix, but clearing without addressing root causes usually makes the light return—and can affect readiness monitors.
Can you diagnose hybrid or newer European vehicles?
Capability varies by model and tooling. Share year/make/model when booking so we confirm coverage before you arrive.
Do I pay diagnostics if I do the repair with you?
Often diagnostic charges are applied or partially credited toward approved repairs—we explain the structure before work starts.
Can you diagnose noises without a code?
Yes—many drivability issues won’t set codes. We use chassis/engine bay inspection and road testing where safe.
What if you can’t find the fault the first time?
Intermittent issues sometimes need a return under the same concern window. We’ll propose the lowest-cost next step rather than random parts swaps.
