To set the ignition timing on a 1997 Volkswagen Cabrio with a 2.0L engine, first, ensure the engine is at operating temperature and then turn it off. Disconnect the timing connector (usually a green wire) to enable the timing to be set at base timing. Use a timing light to check the timing mark on the crankshaft pulley against the timing scale on the engine. Adjust the distributor until the timing mark aligns with the specified timing (typically around 0 degrees BTDC for this engine). Once set, reconnect the timing connector.
