To change the lambda sensor on an Audi TT, first, ensure the engine is cool and disconnect the negative battery terminal for safety. Locate the lambda sensor, typically situated in the exhaust system; you may need to remove any heat shields for access. Disconnect the electrical connector and use a lambda sensor socket or wrench to unscrew the old sensor. Install the new sensor, reconnect the electrical plug, and reattach any removed components before reconnecting the battery.
