2017 audi q7 ac not working have a trouble code B10AE31
The trouble code B10AE31 in an Audi Q7 pertains to the air conditioning system. This specific code indicates a fault in the air conditioning control module.
To diagnose and resolve this issue, you may want to try the following steps:
- Reset the system: Sometimes, a temporary glitch can cause the code to appear. Try resetting the system by disconnecting the car battery for a few minutes and reconnecting it. Then, check if the AC starts working again.
- Check the fuses: Look for any blown fuses related to the AC system. The AC system may not work if there is a blown fuse. Replace any blown fuses and see if that resolves the issue.
- Scan the vehicle: Use an OBD-II scanner or take your vehicle to a qualified mechanic to scan for any additional trouble codes. This will help identify any other potential issues that may be causing the AC problem.
- Inspect wiring and connections: Check the wiring and connections related to the AC system. Look for any loose or damaged wires or connectors. Repair or replace any faulty components as necessary.
- Consult a professional: If the above steps do not resolve the issue, it is recommended to consult a professional mechanic or take your vehicle to an Audi dealership for further diagnosis and repair. They will have the necessary tools and expertise to accurately diagnose and fix the problem.
Remember, working on the AC system of a vehicle can be complex and requires expertise. It is always recommended to consult a professional if you are unsure or unable to fix the issue yourself.
2006 Audi A8 EPC and check engine light.
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.
What can cause vibration from right rear wheel
The most common reasons are listed below. As you vehicle is reasonably new some of the one further down the list will be less likely but it does happen. How long after the repair did the vibration start? If it was on the same day or a few days after take it back to the repairer so they can check their work. On rare occasions even brand new parts can be faulty. It's happened to me with a front wheel bearing. 80 miles and it made more noise than the old one.
I would suggest you get the first 2 on the list checked first as these are the cheaper and simpler fixes.
Wheel and tyre not balanced,
Badly worn tyre,
Warped brake disc,
Worn wheel bearing,
Worn CV joint,
Drive shaft out of balance,
Worn suspension parts.
Audi A6 1.9 TDI (C5) - No communication to car from OBD.
The OBD2 port is connected directly to the ECM and data from other modules is shared from there.
'Mechanics' deal with the mechanical aspects of the car, you need a specialist auto electrician. They have the knowledge and experience and the ability to access and read wiring diagrams.

The first thing to check would be the connectors on the ECM and BCM. Then open them up and look for burned out components.
Full wiring diagrams normally require a website paid or unpaid subscription.

Re-reading the question, did you have one model and year of vehicle and then replace the engine from a different year and model? You can't do that, the ECM has no idea what's going on. ECM are dedicated to the engine it is connected to and programmed accordingly
