Repairs and diagnostics

Warning lights, modules that won’t talk, filters that keep blocking, software that needs updating. The cause is found first, so the fix is the right one.

Diagnosis before parts.

For a warning light, a fault that keeps coming back, a module that needs programming or an airbag light after repairs.

  1. Understand the concern

    What you noticed, when it happens, and anything already tried or replaced.

  2. Identify the vehicle and system

    Exact model, engine, control unit and software version. The right procedure depends on all of them.

  3. Diagnose

    Fault memory, live data and measurements on the circuits involved. A fault code points the way; it rarely gives the answer on its own.

  4. Explain the findings

    What was found, what it means, and the proposed work — before anything on the car is changed.

  5. Carry out the approved work

    Programming, a reset, a repair or new keys — only the work you agreed to.

  6. Verify the outcome

    Fault memory re-read, live data checked, and a road test where it’s relevant.

A typical sequence. The exact procedure depends on the vehicle and the fault, and is confirmed when you book.
