How do you change an oil sensor on a mk3 golf vr6?

To change the oil sensor on a MK3 Golf VR6, first, ensure the engine is cool and disconnect the negative battery terminal. Locate the oil pressure sensor on the side of the engine block, typically near the oil filter. Unscrew the old sensor using a socket or wrench, then install the new sensor by screwing it in place and reconnecting any electrical connectors. Finally, reattach the battery terminal and start the engine to check for leaks and proper operation.
