Hot steam can escape from the expansion tank when the filler cap is opened. Cover the filler cap with a cloth and unscrew it carefully. Note: When the engine is hot the cooling system is under pressure. Carefully open filler cap on expansion tank to release pressure before starting repair work. Hoses are secured with spring-type clips. When repairing only use spring-type clips. VAG 1921 pliers are recommended when installing spring-type clips. The O-rings installed at the quick-release connections must be replaced if damaged or leaking. When installing coolant hoses, make sure that they are free of stress and do not come into contact with other components (observe markings on coolant connection and hose). Perform leak test on cooling system with cooling system tester VAG 1274 and adapter VAG 1274/8.

By a built-in sensor unit, the manifold absolute pressure sensor detects the intake manifold pressure as a voltage. The ECM then determines the basic injection duration and basic injection advance angle based on this voltage. Since the manifold absolute pressure sensor does not use the atmospheric pressure as a criterion, but senses the absolute pressure inside the intake manifold (the pressure in proportion to the present absolute vacuum 0), it is not influenced by fluctuations in the atmospheric pressure due to high altitude and other factors. This permits it to control the air-fuel ratio at the proper lever under all conditions.

The tire pressure warning system informs the driver if it detects a low tire pressure. When the tire pressure warning system detects low tire pressure in any of the 4 wheels which affects safe driving, the tire pressure warning light comes on. Tire pressure warning system is controlled by the Brake Actuator Assembly (skid control ECU). When the tire pressure reset switch is pushed, the tire pressure warning light goes off.

Preparing Vertical Side Panels for the Panzer Plate
1. First, on level ground, raise the front of the car evenly. To do this, you may choose to drive the car onto ramps, jack the car up and secure with two jack stands or use a car lift. If using jack stands or ramps be sure to chock the rear wheels and place the car in gear and firmly apply the handbrake. You should also wear safety goggles during this entire procedure.
2. Once the car is safely raised, remove the Original Equipment Audi plastic belly pan if your car still has one. Next, on the driver side, remove the rear T25 Torx screw from the tail end of the plastic vertical engine bay side panel. In order for the Panzer skid plate to fit, the mounting spot on the subframe where the side panel attaches must not have a Torx screw or side panel attached to it. Retain the T25 Torx screws for the final skid plate install.

The AWE Tuning RSK04 Fueling Kit picks up where the Audi RS4 leaves off! AWE Tuning worked very closely with GIAC to establish the proper mechanical parameters which would overcome limitations in the RS4 that GIAC documented during chip development. The RS4 Mass Air Flow (MAF) sensor and fuel injectors are inappropriate for use on an S4, and we also had our sights set even higher than chipped RS4 territory with the RSK04 kit.
