Adaptation

Basic Setting

Throttle Body

Prerequisites:

  • Ignition ON
  • Engine OFF
  • System voltage at least 11.0 V.

[Select]
[01 - Engine]
[Basic Settings - 04]
Group 060
[Go!]
Activate the Basic Setting.
[ON/OFF/Next]
Wait until Field 4 shows "ADP. O.K.".
[Done, Go Back]
[Close Controller, Go Back - 06]

  • Switch Ignition OFF.


Kick Down

Prerequisites:

  • Ignition ON
  • Engine OFF
  • System voltage at least 11.0 V.

[Select]
[01 - Engine]
[Basic Settings - 04]
Group 063
[Go!]
Activate the Basic Setting.
[ON/OFF/Next]
Press the pedal to the floor and hold it there for at least 2 seconds.
Observe Field 4, once the adaptation is successfully done it should show "ADP. O.K.".
[Done, Go Back]
[Close Controller, Go Back - 06]

  • Switch Ignition OFF.

Fuel Pump

Prerequisites:

  • Ignition ON
  • Engine ON
  • System voltage at least 11.0 V.

[Select]
[01 - Engine]
[Basic Settings - 04]
Group 103
[Go!]
Activate the Basic Setting.
[ON/OFF/Next]
Wait until Field 4 shows "ADP. O.K.".
[Done, Go Back]
[Close Controller, Go Back - 06]

  • Switch Ignition OFF.

Note:

  • Timing chain driven engines such as the CCTA, CBFA and CCTA were phased in during model year 2008. Those engines do not use a G410 (Low) Fuel Pressure Sensor so Basic Settings 103 is not applicable.

Intake Manifold Runner

Prerequisites:

  • Ignition ON
  • Engine OFF
  • System voltage at least 11.0 V.

[Select]
[01 - Engine]
[Basic Settings - 04]
Group 142
[Go!]
Activate the Basic Setting.
[ON/OFF/Next]
Wait until Field 4 shows "ADP. O.K.".
[Done, Go Back]
[Close Controller, Go Back - 06]

  • Switch Ignition OFF for at least 60 seconds.

Notes:

  • Timing chain driven engines such as the CCTA, CBFA and CCTA were phased in during model year 2008. Those engines use an entirely different IMRC system which uses engine vacuum in conjunction with a solenoid so Basic Settings 142 must be completed at idle.
  • Never run Basic Settings with the IMRC motor linkage disconnected from the intake manifold. It may damage the new part.

Readiness

Prerequisites:

  • Ignition ON
  • Engine at idle
  • No fault codes


[Select]
[01 - Engine]
[Basic Settings - 04]
Group 200
[Go!]
Activate the Basic Setting.
[ON/OFF/Next]
Firmly press Brake Pedal and Throttle Pedal (Full Throttle) at once to activate the basic setting.
Field 1 shows the steps counter, which counts down to 0 - then setting readiness is done.
Stay on the pedals as long as the procedure lasts.
[Done, Go Back]
[Close Controller, Go Back - 06]

Special Functions

Checking Fuel Pressure

Prerequisites:

  • Ignition ON
  • Engine ON (Idle)
  • System voltage at least 11.0 V.
  • Coolant Temperature at least 80 °C

[Select]
[01 - Engine]
[Meas. Blocks - 08]
Group 103
[Go!]
Field 1: Fuel Pressure (Low), Specification: 2800...7200 mbar
Field 2: Fuel Pump Adaptation, Specification: -1000...+1000 %
Note:

  • Timing chain driven engines such as the CCTA, CBFA and CCTA were phased in during model year 2008. Those engines do not use a G410 (Low) Fuel Pressure Sensor so Measuring Blocks group 103 is not applicable.


Group 106
[Go!]
Field 2: Fuel Rail,Pressure (actual): 55% or below is normal at idle

  • 55% to 60% is a gray area, it may be okay, but may indicate a problem
  • Above 60% implies there is a failure or restriction
    • Causes of low pressure can include kinks or restrictions in fuel lines
    • Fuel filter issues including restricted/clogged or incorrect part number
    • Failing lift pump in fuel tank. We have seen numerous cases of sub-standard quality "factory" replacements in "factory boxes" that were obtained from aftermarket sources and are not sourced from official dealers. This led to troubleshooting problems that were solved by installing correct factory parts. We encourage customers to only install lift pump and fuel filter sourced directly from a VW/Audi dealer.


Group 140
[Go!]
Field 3: Fuel Rail Pressure (High), Specification: 25.0...110.0 bar
Increase the Engine Speed while checking this value, the Pressure has to rise with the Engine Speed.

Group 230
[Go!]
Field 1: Specified Fuel Rail Pressure (High)
Field 2: Actual Fuel Rail Pressure (High), Specification: 25.0...110.0 bar
Field 3: Deviation between specified and actual fuel pressure, Specification: max. 5.0 bar
