A warning light, a rough idle or a sudden loss of power usually starts with a fault stored in the car’s computer. Engine diagnostics means reading that computer, checking live sensor data and testing the parts involved, so the repair fixes the cause and not only the light. Our Industrial Area workshop works on cars and SUVs from Japanese, German, American, European and Chinese brands. We scan with Autel tools, plus dealer-level tools for Porsche, Audi, Toyota and Nissan. The computer scan takes 5 to 10 minutes, and you get a written quotation before any repair starts.
A code shows where the computer noticed a problem, not always the cause. So after the scan we check live sensor data and test the parts involved.
01
From QAR 150
An engine diagnostic starts with a full scan of the engine, gearbox, ABS, airbag and body modules. We follow it with live data checks and component tests, then explain each fault and what it takes to fix.
02
Traced to the source
A check engine light check starts with the code. The light can mean a loose fuel cap, a sensor fault or a misfire. If a check engine light Qatar garages have cleared keeps coming back, we trace the fault to its source, from reading the code to a road test.
03
Programming from QAR 500
ECU car repair means circuit-board repair when a single component has failed, which often costs less than a new unit. When the unit is beyond repair, we replace it. The ECU programming Qatar cars need afterwards matches the new module to your car, including the coding.
04
Tested first
One failing oxygen, mass airflow or crank position sensor causes many warning lights. We test the sensor and its wiring before replacing it, so a bad connector doesn't cost you a new part.
05
Boost and whine faults
We open and repair superchargers that have lost boost or started to whine. A belt and hose check comes first, so a simple fault isn't blamed on the unit.
Our engine tuning Qatar service is a tune-up that restores smooth running: new spark plugs, throttle body cleaning and injector cleaning, with fault codes read before and after. A tuned engine starts easily and uses less fuel, and in summer, with the AC running almost nonstop, worn plugs and dirty throttle bodies show up sooner.
This is a tune-up, not a remap.
It reads the fault codes stored by the ECU and the modules watching the gearbox, ABS, airbags and body electrics, plus the sensors and wiring that feed them. A broken wire and a failed part can throw the same code.
Check engine light on or flashing, rough idle or stalling, higher fuel use, slow pickup or limp mode, harsh gear changes, or several warning lights at once.
A flashing check engine light usually means a serious misfire, and unburnt fuel can damage the catalytic converter. A steady light on a car that drives normally can usually wait a few days.
Repair work carries a workmanship warranty written on your invoice; consumable parts carry none. We clear codes only once the fault is fixed, then road test. Old parts come back if you ask.
What sets our diagnostic work apart:
You may not need any ECU service at all. A weak battery, a loose earth or a worn spark plug can set the same lights. We take on a car ECU repair Qatar job, or a replacement, only after its power supply, earths, wiring, connectors and sensors are ruled out.
WhatsApp replies come in about 10 minutes during opening hours.
We read every module in 5 to 10 minutes, so most owners wait on site.
Live data and part tests confirm the cause.
You get the fault, the options and a written quotation.
Work starts after you approve.
The diagnostic test fee comes off the repair bill if you go ahead with the repair.
A computer diagnostic test starts from QAR 150, and the fee comes off the repair bill if you go ahead. The written quotation is free. ECU circuit-board repair is priced after the unit is tested, and you see every price in writing before work starts.

☎A steady check engine light on a car that drives normally is usually safe for a short trip to the garage, so book a scan soon. A flashing light, or any loss of power or overheating, means stop driving and call us. Breakdown recovery runs 24/7 through our partner recovery company, including nights and Fridays, from QAR 120 inside Doha, and we confirm the price before the truck is sent.
A computer scan takes 5 to 10 minutes. Tracing an intermittent fault takes longer, and we tell you before we spend the extra time.
ECU programming starts from QAR 500. The final price depends on the car, the module and whether it needs new software or only coding, and you get it in writing before work starts.
A replacement ECU usually needs programming to the car before it works properly. The unit has to match the car's software, options and immobiliser, and we do that as part of the replacement.
Reprogramming an ECU yourself is not worth the risk. A failed or wrong software update can leave the car unable to start, and recovering it costs far more than doing it properly.
An ECU fault can cause sudden power loss, but a sensor, wiring, fuel delivery or limp mode causes it more often. We check those first, then test the ECU itself.
Auto Squad Garage does not program car keys. We repair, program and replace ECUs and scan every module, but key programming is not part of our work.
An engine tune-up starts from QAR 190. The final price depends on the engine and the parts it needs, such as plugs, throttle body cleaning and injector cleaning.
No. Clearing the code only switches the light off, and if the fault is still there the light comes back. We clear codes once the fault is fixed, then road test the car.
A computer diagnostic test starts from QAR 150, and we deduct the fee from the repair bill if you repair with us. The written quotation is free. The ECU scan itself takes 5 to 10 minutes.
