How do you adjust tickover on a seat leon 1.8 petrol engine?

To adjust the tickover (idle speed) on a Seat Leon 1.8 petrol engine, locate the idle speed adjustment screw on the throttle body. Start the engine and let it warm up to operating temperature. Using a screwdriver, turn the screw slowly to increase or decrease the idle speed until it reaches the manufacturer's specified RPM, typically around 800-900 RPM. Always ensure the engine is running smoothly and check for any vacuum leaks that might affect idle stability.
