Computer diagnostics
Modern cars need the right scan tools — not a bargain-bin code reader. We use professional Bosch diagnostic equipment to identify faults and repair them properly.
Workshop-first service — call if you are unsure what the car needs.

When the warning light comes on
Today’s vehicles constantly monitor the engine, transmission and related systems through OBD-II. When a signal goes outside its normal range, a fault is stored in the ECU and a warning light appears — even if the car still “seems fine” to drive.
Ignoring some lights can lead to serious damage and higher repair costs. A diagnostic scan reads the stored message, points the investigation, and clears codes only after the cause is fixed.
Common symptoms we investigate
- Difficult to start
- Intermittent stalling
- Excessive exhaust smoke
- Higher fuel use than usual
- Hesitation or sluggish acceleration
- Engine misfire
- Dashboard warning lights
ECU diagnosis and repair
Poor fuel economy and hard starting can point to ECU or related control issues. We diagnose the fault path first, then repair or replace as required — including programming pathways where the job needs it.
Related case studies live under Diagnostics as we rebuild them from the archive.
