Audi A5 (8T) Active/Dynamic Steering

Indentation as used on talk pages:

Each colon at the start of a line
causes the line to be indented by three more character positions.
(The indentation persists

so long as no carriage return or line break is used.)

Repeat the indentation at any line break.
Use an extra colon for each response.
And so forth ...
And so on ...


Centered text


function int m2() is nice.


You can strike out deleted material and underline new material.

Coding

Coding for this Control Module is normally done via Software Version Management (SVM). If the old Control Module is still accessible read/copy it's Coding to the new Module.


Basic Setting

1B-Active Steering

Prerequisites:



- Continue Only after successfully completing the G85 basic settings -

  • Leave the steering wheel in the straight ahead position during the next steps.


[Select]
[1B-Active Steering]

[Security Access - 16]
Enter 61378, to enable the basic setting.
[Do it!]


[Basic Settings - 04]
Group 101
[Go!]
[ON/OFF/Next]

  • The results should be stored after a key cycle and fault code(s) should clear.


[Done, Go Back]
[Fault Codes - 02]
Check and clear fault codes.
[Close Controller, Go Back - 06]

18613/P2181/008577 - Performance Malfunction in Cooling System

Possible Causes

  • Faulty Coolant Sensor
  • Faulty Coolant Thermostat
  • Faulty Wiring, Connections

Note: This fault code sets when engine coolant temperature mapping is lower and out of expected range based on operating conditions of the engine.

  • For example: Engine warms up, thermostat opens and stays open, coolant temperature drops below normal operating range. The ECM knows the coolant temperature should stay within 80.0...110.0 °C typically after warm up. Thus a drop in coolant temperature below normal operating temperature is not possible without a malfunction in cooling system.

Possible Solutions

  • Check G62 - Engine Coolant Temperature Sender
    • Inspect wiring for G62 (Coolant Migration, damage, corrosion, etc)
  • Check (if applicable) G83 - Radiator Outlet, Coolant Temperature Sender
    • Inspect wiring for G83 (Coolant Migration, damage, corrosion, etc)
  • Check Coolant Thermostat
    • Use Graph function in VCDS, Measuring Value Blocks - MVB
    • Start Engine cold, graph Coolant Temperature Sender (G62) Typically MVB Group-001
    • Hold RPM around 1,500rpm and watch coolant temp increase in Graph until thermostat opens, indicated by a slight drop in coolant temp
    • If coolant temp drops below minimum operating temperature (80°C) or never reaches operating temperature, (verified by external thermometer) suspect failed thermostat
  • Vehicles with both G62-Engine Outlet, Coolant Temperature Sensor and G83-Radiator Outlet, Coolant Temperature Sensor
    • Use Measuring Value Block group MVB-130 instead on MVB-001
    • G62 should increase in Temperature before G83 increase when engine coolant is cold
    • G83 will increase when the thermostat opens and after G62 reaches operating temperature (80°C)
    • If G62 and G83 both increase while engine warms up, suspect failed thermostat


Special Notes

  • Check the stored Freeze Frame data with this fault code. Freeze Frame information will be found in the fault code description (if the module supports it) or in Generic OBD-II if the vehicle complies with those regulations.
    • Freeze Frame data stored at -40*C is generally an indication of a faulty ECT or wiring.
    • Freeze Frame data stored at +140*C is generally an indication of a faulty ECT or wiring.
    • Freeze Frame data stored with in the 68*C ~ 80*C range is an indication that the vehicle was close to, but not within, the cooling systems normal operation range. The Thermostat itself or Cooling system components may be at fault.




Clean Diesel Readiness Status (non UDS Controllers)

This information can be found in the [01-Engine] Measuring Value Blocks in the form of binary data.

Below is a guide so it is possible to read and understand the binary data in the fields.

  • Measuring Value Block Group [089]
    • Field 1 - 0000 0000 - Fault codes stored and Check Engine Light Status
    • x??? ???? - Fault code count in binary
    •  ?xxx xxxx - Check Engine Light On = [1], Off = [0]

Field 2 = 0000 0000 ?xxx xxxx - N/A x?xx xxxx - Comprehensive component monitor readiness status, Incomplete = [1], Complete = [0] xx?x xxxx - Fuel system monitor readiness status, Incomplete = [1], Complete = [0] xxx? xxxx - Misfire monitor readiness status, Incomplete = [1], Complete = [0] xxxx ?xxx - Ignition monitors - Spark or Compression , Supported Function = [1] xxxx x?xx - Comprehensive component monitors, Supported Function = [1] xxxx xx?x - Fuel system monitor, continuous, Supported Function = [1], Not Supported = [0] xxxx xxx? - Misfire monitor, continuous, Supported Function = [1], Not Supported = [0]

Field 3 = 0000 0000 - Monitors that are supported ?xxx xxxx - EGR/VVT System Monitor, Supported Function = [1], Not Supported = [0] x?xx xxxx - DPF (Diesel Particle Filter) Monitor, Supported Function = [1], Not Supported = [0] xx?x xxxx - Exhaust Gas Sensor Monitor, Supported Function = [1], Not Supported = [0] xxx? xxxx - Not used on diesel vehicles at this time xxxx ?xxx - Indicates Boost Pressure System Monitor, Supported Function = [1], Not Supported = [0] xxxx x?xx - Not used on diesel vehicles at this time xxxx xx?x - NOx/SCR After-treatment Monitor, Supported Function = [1], Not Supported = [0] xxxx xxx? - NMHC Catalyst Monitor, Supported Function = [1], Not Supported = [0]


Field 4 = 0000 0000 - Readiness status of the supported systems ?xxx xxxx - EGR/VVT System monitor readiness status, Incomplete = [1], Complete = [0] x?xx xxxx - DPF readiness status, Incomplete = [1], Complete = [0] xx?x xxxx - Exhaust Gas Sensor monitor readiness status, Incomplete = [1], Complete = [0] xxx? xxxx - Not used on diesel vehicles at this time xxxx ?xxx - Boost pressure system monitor readiness Status, Incomplete = [1], Complete = [0] xxxx x?xx - Not used on diesel vehicles at this time xxxx xx?x - Readiness status of NOx/SCR After-treatment Monitor, Incomplete = [1], Complete = [0] xxxx xxx? - Readiness status of NMHC Catalyst Monitor, Incomplete = [1], Complete = [0]
