Vehicle Diagnostics

Reading a fault code takes a minute. Working out what it means takes experience.

CPA Motorworks diagnoses vehicle faults in Limassol by testing the circuit before condemning a component. A stored fault code names a circuit, not a broken part, which is why the same warning light produces different repairs at different garages.

Marque-specific diagnostics — circuit tested before a part is condemned

A code is a symptom, not a diagnosis

A sensor reporting an out-of-range value might be a failed sensor, a chafed wire, a connector full of moisture, or a genuine mechanical fault the sensor is correctly reporting. Replacing the part named in the code is the fastest way to spend money and still have the problem. We test the circuit before we condemn a component.

What you get back

A plain explanation of what we found, what it will take to fix, and what can safely wait. If something is worth watching rather than repairing today, we will say so — and if we cannot find a fault, we will tell you that too rather than guess at one.

• A warning light has come on and stayed on
• The car runs, but not the way it used to
• A noise that comes and goes, or only when cold
• It failed an inspection and you were not told why
• Another garage replaced a part and the fault came back

Can you diagnose a fault that only happens sometimes?

Usually, yes, but it takes longer. Intermittent faults often leave freeze-frame data stored alongside the code, which records what the engine was doing at the moment it appeared — cold, hot, under load, at a particular speed. That is frequently enough to reproduce it deliberately rather than wait for it.

Do I need a main dealer to diagnose a BMW?

No. An independent workshop with marque-specific diagnostic access reads the same modules and the same data the dealer does. What differs is the price and who you speak to about it.

What happens if you cannot find anything wrong?

We tell you that. A diagnosis that finds no fault is a real result and it is worth knowing, and we would rather say so than invent a repair to justify the time.

Should I clear the warning light before I bring the car in?

No. Clearing the code wipes the data the car stored when the fault occurred, and a reset light hides an intermittent fault until it decides to come back. Bring the car as it is, light on.
