RS4 maintenance
This page contains our videos on the various Audi B7 RS4 build and maintenance items with our Frooog race car but also our daily driver RS4.
Stud conversion
One of the most convenient and necessary modification for any RS4, a stud conversion kit will make changing wheels so much easier and not need to have different sets of bolts if you are using spacers.
Windshield washer pump
The RS4 has 2 washer pumps, one for the windshield and another one for the headlights, one on each side of the washer tank. Thankfully the windshield washer pump is the most accessible one!
Interior and rollcage
In this section you will find the videos related to the interior removal and rollcage construction.
Cartek GT kill switch installation
If you want to learn more about kill switches, check out our Kill switch page.
If you retain the factory key so that the immobilizer and other security features remain enabled, you will have to use a relay to control the ECU fuse. You can use the Cartek GT ECU power lead to power the relay and the ignition lead from the fuse to control the relay. This way if you shut off the ignition or lose power from the Cartek, the car will shut off in both cases.
The diagram below shows how to wire a Cartek GT on the Audi RS4 by tapping fuse #43 (engine management/ECU) that is located on the side of the dash on the driver side. You can look at the accompanying video to see how we routed the wires through the car and installed the Cartek GT near the battery in the trunk.
