Why diagnostics first?

Carbon cleaning restores combustion efficiency, but it shouldn’t hide underlying faults. A quick scan and health check up front tells us what the engine is doing right now: sensors, fuel trims, misfire data, DPF soot load, temperatures and more.

  • Safety & suitability: confirm it’s appropriate to proceed today.
  • Right service, first time: if a mechanical/electrical fault exists, we’ll advise the fix instead of guessing.
  • Proof of improvement: repeat the same checks after the job so you see the change.
  • Prevents wasted spends: no “parts darts” — data guides the decision.
Planning a diesel booking? Diagnostics confirms DPF conditions (soot load, pressures, temps) to support healthy regeneration and the right remedy.

What we check

Equipment varies by vehicle; here’s the typical scope:

  • OBD scan — fault codes (current/pending/history), readiness monitors.
  • Live data — fuel trims, MAF/MAP, O₂/λ, boost, EGTs, coolant/oil temps, DPF soot/pressure.
  • Visual & sound checks — leaks, intake ducting, vac lines, abnormal noises.
  • Battery/charging — voltage stability & alternator output (many faults are voltage-related).
  • Road assessment (where safe) — drivability, flat spots, limp mode behaviour.

What you receive

  • Baseline snapshot: codes & key live data before any work.
  • Post-service snapshot: the same metrics after, so you can compare.
  • Plain-English summary: what we found, what we did, what to do next.
  • Maintenance advice: tailored to how and where you drive.

We can email a PDF summary to you after the appointment if you’d like a record.
