Engine and gearbox
Check-engine lights, poor starting, hesitation and gear-change concerns can call for engine or transmission data. A warning alone does not establish that an engine or gearbox needs replacing.
Warning lights and fault finding
Car Computer Check in Dubai
A warning light has come back, the engine feels rough, or an electrical fault keeps interrupting your day. Book a car computer check at our Al Quoz workshop. We read the information your car has recorded, explain the findings and discuss any further tests before you spend money on repairs.
Share the warning message and your car’s make, model and year.
Start with what changed
You do not need a fault code before you call. Tell us about the warning, the hesitation when you accelerate, the difficult start or the function that has stopped working. The complaint helps us decide which control units and readings are relevant.
A computer check can retrieve diagnostic trouble codes, often called DTCs, from the systems the vehicle allows us to access. Those records give the technician somewhere useful to start.
If the car is unsafe to drive: stop safely for overheating, loss of braking or severe rough running. Follow the vehicle’s warning instructions and call about getting it to the workshop.
Standalone computer check
What does a scan cost?
- Standard sedanInitial computer check for one vehicle
- AED 150–250
- Luxury carThe required diagnostic access affects the work
- AED 300–500
These are our previously published guide ranges. Their VAT basis is unconfirmed; ask for the current total and whether 5% VAT is included before booking.
Agree what the appointment covers
Confirm the systems to be checked and the available report. Access varies with the make, model, year and equipment; a generic OBD-II scan and a manufacturer-specific check do not necessarily reach the same modules.
Tracing wiring, testing mechanical components or reproducing an intermittent fault may need further diagnostic time. That work is quoted separately, as are parts, repairs, programming and calibration unless expressly included.
A free initial check offered with a repair enquiry may differ from a booked standalone scan. Confirm the applicable charge; a scan fee is not automatically credited against a later repair.
Understanding your fault codes
The part named in a fault description may not be the part that needs replacing. Wiring, connections, power supply and mechanical condition can affect what a control unit detects.
We read the fault information alongside your complaint. Where it is available, the following context helps decide what to test next.
- Current, stored or intermittent
- A fault present now needs a different explanation from an event recorded earlier. The labels depend on the vehicle and diagnostic software.
- The conditions when it happened
- Freeze-frame data records certain readings at the time a fault was registered. Temperature, speed or load may help connect it with a cold start or another driving condition.
- What the car is doing now
- Live data shows readings while the car operates. The technician compares them with the expected behaviour; one number on a screen is not enough to diagnose a failure.
- Readiness after a reset
- On supported vehicles, readiness monitors show whether the car has completed its emissions self-checks. A “not ready” result means a check is incomplete, not that the named part has necessarily failed. Clearing codes or disconnecting the battery can reset these checks, so mention any recent reset.
- A permanent code after repair
- Where permanent emissions codes are supported, a scan tool cannot simply erase them. The vehicle must run the relevant self-check and confirm that the fault is no longer present. The record needs to be read alongside current faults and test results.
Warnings we can investigate
ABS, stability and airbags
Supported control-unit faults can help identify the next sensor, wiring or physical checks. Clearing an ABS or airbag warning is not a repair of the braking or restraint system.
Electrical and comfort functions
Climate-control complaints, intermittent functions and communication errors may involve several modules. When several report faults together, a shared power-supply or communication problem may need checking.
Tell us the exact warning before booking so the required access can be confirmed, including for hybrid and electric vehicles. A general diagnostic appointment does not include high-voltage battery dismantling or repair.
Your scan results and next steps
A useful result connects the scan with the problem you brought in. Ask for the available report and an explanation of what was confirmed, what remains uncertain and whether any repair is recommended.
- The control units checked and any access limitations.
- The relevant codes and their status during the visit.
- Any further tests needed, with their charge agreed first.
- A written estimate for recommended repairs.
If a fault only appears occasionally, tell us whether the engine is cold or warm, what you are doing and how often it happens. Mention recent battery work, repairs or accessories. It may take more than one observation to reproduce the complaint.
No codes, but the problem remains? A scan cannot rule out wear, leaks or every intermittent fault. A noise or fluid loss may need a mechanical inspection. For a used-car purchase, combine electronic checks with a physical inspection; a clean scan does not prove the car is free from accident damage or future faults.
Before your appointment
Send the car’s make, model, year and warning message when you enquire. These details help us confirm the right check.
Can I wait while you check the car?
Ask when booking. Reading the available fault information and tracing the cause can take different amounts of time. An intermittent fault, an inaccessible module or further testing may mean leaving the car with the workshop.
The warning returned after a repair. What should I bring?
Bring the previous scan report, repair invoice and any notes about when the warning returned. Earlier findings help us compare the same complaint without assuming that every stored code is new.
Does the price include fixing the fault?
The guide prices cover an initial computer check. Additional diagnosis, parts and repairs need a separate agreement. Confirm the available report, the final fee and VAT treatment before the appointment.
Is ECU programming included?
Programming, coding, module repair and calibration are separate jobs unless specifically included in your quotation. Reading a control unit does not mean it needs to be reprogrammed.
Can the scan find every electrical fault?
No. The result depends on which systems can be accessed and what the car has recorded. Wiring, power-supply and intermittent faults may require physical tests beyond the scan.
Is this an official vehicle test?
No. A workshop computer check is a diagnostic service. It does not replace an official vehicle-testing certificate.
