oil gauge and taillight

Hi aleyküm friends I just joined you 2004 pejo 206 XT model vehicle on the way while driving on the road, stop and oil light flashes instantly said that it was from the filter.

The sender is the original or sub-industry. Subcontractor may also have problems. If the stop light and the parking brake light are blinking, they do so from the brake fluid. You said above that it flashes instantly. Maybe not the oil that was lit, the handbrake warning light was flashing. If you are sure that you are fat, it is likely that your fat level is normal.

The oil sensor was originally installed, the handbrake light did not come on, but we did not solve it.
