Car Diagnostics and Computer Scan jobs we do
Full computer scan
We read the stored and pending fault codes from every module in the car, including the engine, gearbox, ABS, airbag, body and comfort systems. A fault in one module often sets codes in others, and the full list shows which one started it.
Live data and testing
A fault code points to a circuit, and the part named in it is often fine, so we read live data such as sensor values, fuel trims and temperatures with the engine running. Then we test the wiring and the suspect part before anything goes on the quote.
Check engine and other warning lights
The check engine light covers the engine and emissions, while the ABS, airbag, traction and gearbox lights each come from their own module. A red or flashing warning means stop as soon as it is safe, and an amber light means book a scan soon.
Dealer-level tools for Mercedes-Benz, BMW and Porsche
On these makes many faults sit in the body and comfort modules, which a basic code reader cannot see. Our dealer-level tools read every module and run the tests and resets that a repair needs.
Car Diagnostics and Computer Scan questions
What does a car diagnostic test show?
It reads the fault codes stored in each module and what the car was doing when each fault happened, and the live data shows how the sensors and parts are working now. Testing then confirms which part has failed. A scan cannot see wear that sets no code, such as a worn bush or a slow oil leak, so we look at the car as well.
The check engine light is on but the car runs fine. What should I do?
Book a scan soon and drive normally until then. A steady light with no symptoms is often a sensor, a small evaporative leak or a loose fuel cap, but it can also be an early fault that costs more if it is left. If the light starts flashing, ease off and stop as soon as it is safe.
Can I drive with a flashing check engine light?
Only as far as a safe place to stop. A flashing light means a misfire, which sends unburnt fuel into the exhaust, where it can overheat and destroy the catalytic converter. Avoid hard acceleration and get the car checked before driving further.
Is it serious if the check engine light comes on after an oil change?
Usually not, but have it checked. An oil filler cap that is not seated properly can let air into the engine, and a sensor plug can get knocked loose during the job. If the red oil pressure light comes on, stop the engine straight away, because that is a separate and serious warning.
Why are several warning lights on at once?
Low battery voltage is the most common cause, because the modules log faults when the voltage drops during starting. A failing alternator, a loose earth cable or a fault on the network that links the modules can do the same. A scan shows which module logged its fault first, and that usually points to the cause.
Do you collect the car?
Yes, free, anywhere in Dubai during working hours. We collect the car from your home or office, from Dubai Marina and JLT to Downtown, Business Bay, Mirdif and Dubai Silicon Oasis.
