Sometimes the service light on the Audi A4 B6 may not reset, and here are the most common reasons: first, consider the hood release switch. If the light stays on, you need to open and close the hood so the system can recognize that you've added oil. In the video, we see that the micro switch had broken wires, causing the control module to think the hood is always closed.

Check by turning on the ignition and opening the hood: if the open hood light doesn’t come on, then there is a problem with the switch. There is a second possibility: the YouTuber discovered that on some control modules, the service signal and the oil level check may be linked, so resetting the service also resets the oil level light memory.

Another issue not mentioned in the video could be the sensor itself, located in the oil pan, which may be faulty.

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
