How to install an LED to indicate the regeneration of the particulate filter on the Peugeot 3008

Model: Peugeot 3008 MK 2, P84 - Years 2016-2023
Part: Checks and maintenance

In this video, we see how to install a LED that indicates the regeneration of the particulate filter on the Peugeot 3008: we will need a LED, a resistor (330/470 Ohm) to avoid overloading the car's circuit, an electrical wire, heat shrink tubing, an extension cable with OBD2 connector (optional but very useful for a simple and safe method). The YouTuber shows how to remove the driver's side glove compartment, and in the fuse box identifies the number 6 wire (purple/white color), which is connected to the lambda sensor, which is the signal that is activated during regeneration. We cut the wire, connect the anode of the LED (the positive pole, the longer leg) to the side of the wire that goes to the ECU; we connect the cathode (the negative pole, the shorter leg) through a resistor to the side of the wire that goes to the lambda sensor - without the resistor, the LED would burn instantly - we position the LED: the YouTuber has fixed it with a small hole in a corner of the glove compartment with some glue. This way it is clearly visible but not bothersome.

How to Reset the Tyre Pressure Light on the Opel Grandland X

While driving, if you notice the tyre pressure warning light coming on, first check the actual inflation pressure of the tyres and, if necessary, restore the pressures recommended by the manufacturer. After restoring the correct pressures, you need to reset the warning light that has illuminated on the instrument cluster. To do this, locate the reset button on the lower central console. Press this button and hold it down for at least 3 seconds, after which the low pressure indication will turn off.
