How do you change the tappets on a golf gti?

To change the tappets on a Golf GTI, first, ensure the engine is cool and disconnect the battery. Remove the valve cover to access the tappets, then carefully take out the old tappets using a suitable tool or your fingers, making sure to note their orientation. Install the new tappets in the same position, reassemble the valve cover, and reconnect the battery. Always consult the vehicle's service manual for specific torque specifications and procedures.
