S5 error codes help

Code 51 is the Fuel pump and resistor relay and not as how you labeled it. Is your car running okay or are you having hesitation issues when under load?
The other two codes are emission related. Have you removed part or all of the emissions equipment? I believe they are both part of the ACV.

The error codes only tell you if the voltage readings to the two solenoids are correct or not and not if the ACV works or not as the ECU does not receive that type of feedback information. The front solenoid at the ACV is the Port Air Solenoid which has two wires. One is Black/White while the other is Blue. The Blue wire has idle voltage of 2 volts (this ocurs if the mileage is between 20k and 100k, if the mileage is between 100k and 120k then the voltage at idle is 12 volts, if greater than 120k then it is 2 volts) and w/engine rpm above 3500 it is 12 volts. The Split Air Solenoid, closest to the firewall, also has two wires where one is Black/White and the other Blue/Red. The Blue/Red wire has 12 volts in gears 1 through 4 and when in 5th gear it is 2 volts.

The device which is throwing the code is responsible for boosting the voltage to the fuel pump when the engine is under load. Are you having problems w/the car hesitating or lagging under acceleration for if not then you could just leave it be until the performance of the car is hindered.

The Fuel Pump Relay has one plug w/six wires. Three are Blue/red, two are Blue/Green and I think the last wire is Green/Red but the relevant wires are the other five wires. So disconnect this plug and jumper one of the Blue/Red wires to one of the Blue/Green wires and this will bypass the relay.

The air filter you have connects to the AFM. The relay you are looking for has the one plug as mentioned w/the six wires as mentioned. Since there is only one plug in the car w/those six wires and this device is to be located under where the air box is or went it should not be too difficult to find the relay.
