The battery is under the spare tire. . .

All you can do is have the codes read and have the problem repaired.You can drive it that way, it will be 20% down on fuel economy with the light on but usually will have lower emissions!

Check the gear box oil level sounds low to me i had a similar problem with a auto box car before and as for your steering it could be a worn steering rack if the oil level is good

a/c temp pressure sensor could be the main temperature sensor, you will need access to the factory service computer, you may have a leak in your system so it will have to be checked at the dealer, sorry hate to say that, you can try the sensor first, just get one at a parts store or online, it's going to be a gamble without testing the system,does the ac get cold?

I had the same problem with my 2014 RS5. The solution was to keep pressing and releasing the gate remote until it was picked up by the Audi, instead of just pressing and holding the gate remote button. My gate has a Mighty Mule gate opener but the remotes are the same for most makes of gates.

Check the codes!

I would check the OBD codes for clues.

Try the row of large switches above the radio. It is most likely the middle one.

Let's break down the situation: EPC Light: The EPC light typically comes on when there's a problem with engine sensors or components. It might be related to the throttle sensor or the temperature sensor. When the EPC light activates, the engine electronics may limit power and maximum RPM. As a result, the computer might restrict the engine's performance, allowing you to drive at low speeds only. Check Engine Light: The Check Engine light illuminates when the engine management system detects a fault or error. The codes you've provided indicate specific issues: Code 17950/P1542/005442: Angle sensor 1 for Throttle Actuator (G187) has an implausible signal. Code 16891/P0507/001287: Idle Control System RPM is higher than expected. Possible Causes and Solutions: Fuel System Issues: Given the fault codes related to fuel pressure, it's essential to check the fuel system. Low fuel pressure could cause hesitation and trigger both lights. Mass Airflow Sensor (MAF): A faulty MAF sensor can lead to engine hesitation, rough idling, and stalling. Consider inspecting or replacing the MAF sensor. Throttle Body: Although the dealer replaced the throttle body earlier, it's worth verifying its functionality again. Idle Control System: The high RPM issue might be related to the idle control system. Inspect the idle control valve and related components. Wiring and Connections: Check for loose or damaged wiring, connectors, and vacuum lines. Next Steps: Diagnostic Scan: Perform a thorough diagnostic scan to identify any additional fault codes. Visual Inspection: Inspect the throttle body, angle sensor, and wiring connections. Fuel Pressure Test: Verify fuel pressure using a fuel pressure gauge. MAF Sensor: Consider cleaning or replacing the MAF sensor. Idle Control Valve: Inspect the idle control valve for proper operation. Remember that intermittent issues can be challenging to diagnose. If the problem persists, consult a qualified mechanic or an Audi specialist to pinpoint the exact cause and address it effectively.
