Audi A4 - Video tutorial

Model: Audi A4 B6 - Years 2000-2004
Part: Key
Operation: How to replace the battery of the key A4

How to replace the battery of the remote control key of an Audi A4? Let's see in detail how to do it: take our remote control and press the button to release the metal key (if present). Once extracted we go with a lever to separate the two covers (as in the video). We extract the empty battery from the housing (after having separated the two halves of the covers), let's take a new one of the same size and voltage. We reassemble the plastic battery holder in the remote control cover, finally insert the metal key into the cover. We check the exact operation of the remote control.

How to replace the pollen filter mounted inside the engine compartment of a Peugeot 2008? Let's see in this video how to disassemble the filter placed in the dedicated housing. With a screwdriver we unscrew the screws of the plastic coating placed under the front windshield, then, with a lever, remove the filter holder cover (where the air filter is present). Remove the cap from the filter holder with a screwdriver and extract the cabin filter. We insert a new filter making it adhere well around the walls of the box.
