All-module scan
Engine, transmission, ABS, airbag, body, infotainment, gateway. Stored, pending and historical codes, on every module the car runs.
The dashboard light is the start of the conversation.
A code reader at the discount chain will tell you something failed. We tell you why, what it will cost to fix, and whether it was actually the cause or just a symptom.
Beyond a code-pull
What manufacturer-grade diagnostics actually means.
Most generic OBD readers tell you a fault code, and that is all. A manufacturer platform tells you which sensor saw what value, when, and under what conditions. It lets us watch a misfire happen on a road test rather than guess from a stored P0301. It lets us perform actuator tests — open and close that EGR valve on demand, listen to that turbo wastegate move — and confirm the part is genuinely at fault before you pay for one.
That difference is what stops you replacing a perfectly healthy oxygen sensor because the lambda-bank-1 short-term-fuel-trim looked vaguely high in a parts-reader app.
Diagnostic depth
What our diagnostic visit covers.
Live data & logging
Live values for the sensors that matter to the fault, logged across an idle phase and a road test so we can see the fault happen in context.
Actuator tests
Bidirectional commands to the ECU — fire an injector, cycle the EGR valve, open the throttle plate — to confirm whether the part itself is responding.
Coding & adaptations
Battery registration after replacement, throttle-body adaptation, steering-angle calibration, injector-quantity coding on the diesels we cover.
Compression & leak-down
For misfires that don't show in the live data — a wet/dry compression test and, where indicated, a cylinder leak-down to identify a tired valve or piston ring.
Smoke & pressure tests
Boost-leak smoke tests for diesels and turbocharged petrols, and cooling-system pressure tests for the slow loss that's hard to see on the floor.
Output
What you get at the end of a diagnostic visit.
You leave with a written report — the codes we found, the live data we logged, the tests we performed, and the conclusion. If the next step is a part replacement, we quote the part replacement. If the next step is a deeper strip-down, we quote that and explain why it is justified before we open anything up.
If the verdict is "this car is on the wrong side of economic repair", we will tell you that too. We would rather lose a job we shouldn't take than send you home with an invoice you'll resent.
