Idle Speed Control Valve Cleaning Cost in UAE (2026)
The idle speed control valve (also called the IAC — Idle Air Control valve) regulates the amount of air entering the engine at idle. When carbon deposits and oil residue build up on the valve, the idle becomes rough, erratic, or the engine stalls at traffic lights. In UAE conditions, where engines idle frequently in heavy traffic and heat causes more vapour deposits, the IAC valve requires periodic cleaning.
Typical Costs in UAE (2026)
| Service | Estimated Cost (AED) |
|---|---|
| IAC valve cleaning (off-car) | 100-250 |
| Throttle body + IAC cleaning combined | 200-400 |
| IAC valve replacement | 250-700 |
IAC valve cleaning is often combined with throttle body cleaning since both components work together to regulate idle air flow. Cleaning both at the same time is more economical than separate visits and addresses the full idle system.
Symptoms of a Dirty IAC Valve
Watch for: an unstable or hunting idle that surges up and down, engine stalling at traffic lights when coming to a stop, difficulty starting when the engine is warm, and a rough idle that smooths out once the engine is revved and then returns to the stall point. The check engine light may also appear with an idle-related fault code.
Can IAC Valve Cleaning Be Done Without Replacement?
In most cases, yes. The valve is removed from the engine, cleaned with a specialist spray or ultrasonic bath, and reinstalled. If the valve stepper motor or internal winding has failed, cleaning will not restore function and replacement is required. A mechanic can test the valve electrically to determine whether cleaning or replacement is needed before committing to either.
