The idle speed of Audi q3 is normal. Can the idle speed of Audi q3 be adjusted?

The normal idling range of Audi Q3, taking 2.0T as an example, is 700-750r/min for non-idling and 800-850r/min for idling. The following is the adjustment method when the idle speed is abnormal. When the idle speed of the engine is unstable, first check whether the idle hole and idle air hole are blocked. If the orifice is blocked, it can be cleaned with gasoline or acetone and purged with compressed air. If the measuring hole is not blocked, the engine speed should be stabilized at a certain speed, and whether the intake manifold or the lower gasket of carburetor leaks air. If there is air leakage, it can be eliminated by fastening screws or adding or subtracting gaskets. If the idle speed is unstable and the engine power decreases, the working condition of the spark plug, the sealing performance of the valve and the ignition time should be further checked, and maintenance and adjustment should be carried out if necessary. Idle speed adjustment must be carried out under normal conditions such as normal engine temperature, proper valve clearance, normal ignition system, good pipeline sealing, full throttle opening and tight throttle closing. When adjusting, first loosen the throttle opening adjustment screw to make the engine reach the lowest stable speed. Then screw in the idle speed adjusting screw with a screwdriver. When the engine is about to turn off, slowly loosen the idle speed adjusting screw to make the engine run smoothly and reach a high speed. Then, loosen the throttle opening adjustment screw to reduce the engine speed. Then adjust the idle adjustment screw to increase the engine speed. Repeat this process until the throttle opening is minimum and the engine runs at the lowest stable speed. Finally, increase the speed and suddenly close the throttle, so that the engine can still turn without stalling.
