2004 Audi A4 Avant USP Project – Pt 2

In episode #2 of the Audi Ultrasport project, we discuss a possible oil pressure issue and then move on the next big problem: The alarm siren keeps going off!

Here are some handy shortcuts:

Disassemble the rear of the car to retrieve the module (1:16)
Cut open the module (9:25)
Remove the leaking battery (10:36)
How to clean the board (16:18)
Reinstall the module & reassemble the back of the car (20:00)
Re-sync the key and test the module (23:20)


Here is a list of the items we mentioned in the video:

Alarm module (8L0951605A) CHEAPER THAN THE DEALER!
Torx screwdriver set
De-soldering iron
Soldering Iron
Helping Hands
7.2v NiMH Battery

While we were working to fix the alarm siren, we found a LOT of pet hair and dirt in the back of the car. We’ll be cleaning the interior of the car soon!

We also found a water leak that will also be the subject of another video.

If you have questions, comments, or suggestions, please post them in the video comments on YouTube. Thanks!
