=== Injector Quantity Adjustment (IMA) and Injector Voltage Adjustment (ISA) ===

''These values represent the behavior of an injection valve (Piezo Injector). Caused by manufacturing tolerances the injectors have a unique behavior and get divided into separate classes. In combination with the automatically determined learning values of the engine control module the pre- and post-injections are being calculated individually for each valve.''
''The behavior of an injection valve is also mileage dependent, so a valve with e.g. 10000 km has a different behavior then one with 70000 km. The control module determines these automatically while driving so the learning values change against the mileage.''
''When altering one of the following values the learning values are being reset because the ECU thinks you are adjusting a new valve.''

'''The IMA-ISA values need to be adapted when:''' 

* One or more injection valves have been replaced. Make sure not to adjust the valves which have not been changed!
* The engine control module has been replaced.
* ''Do NOT adapt these values when you did not replace one of the above parts, also not for training or demonstration purposes.''

The adjustment code can be found on the injector itself, it is a 7-digit value and does only use the following chars: 1,2,3,4,5,6,7,8,A,B,C,D,E,F,G,H,K,L,M,N,O,P,R,S,T,U,V,W,X,Y,Z. ''A value of ''AAAAAAA'' is also not valid.''

'''[Done, Go Back]''' 
* Switch Ignition OFF, wait 10 seconds and switch Ignition ON again. The values should be saved now, please verify them by double checking the adaptation values.

* The Test value shows "AAAAAAA" if you have entered an implausible value. If the IMA-ISA value on the new injector is difficult to read, consider scanning the QR code with a smart phone app.
**We have had success with BB, Android and iOS platform mobile devices running i-nigma's free app. 

* If the Injector Calibration value is submitted correctly, but the ECM rejects it (Request out Range), please verify the correct injector part number has been installed.

=== Particle Filter Emergency Regeneration ===

'''Prerequisites:''' 
* Ignition ON
* Engine ON (Idle)
* Oil Temperature above 70 °C ''(see MVB 007.2)''
* Particle Filter Load below 68g ''(see MVB 104.3)''
** If the Particle Filter Load is above 68g the Particle Filter needs to be replaced since the car may burn down when regenerating.
* Engine Hood CLOSED
* Parking Brake ENGAGED
* Transmission in (P)ARK
* Temperatures at the Exhaust System may rise up to 300 °C!!!
* No Fault Codes Stored
* Power Consumers ON ''(Light, Seat Heating, Front/Rear Window Heater, Climate Control)''

The Regeneration may take up to 40 minutes, the engine speed automatically increases to about 1500 RPM.

== P026A/000618 - Charge Air Cooler: Efficiency Below Threshold - MIL ON ==

==== Possible Symptoms ====

* Malfunction Indicator Lamp (MIL) active
* Reduced engine output

==== Possible Causes ====

* Intercooler restricted (internal or external)
* Faulty sensor
* ECM firmware issue

==== Special Notes ====

* On some TDI CR engines, a faulty G42 / G31 sensor at the top of the intercooler may report a much higher than possible temperature:
** IDE04938 - Sensor for temp after charge air cooler: raw value
** [https://forums.ross-tech.com/index.php?threads/32948/ Case Study - P026A/000618 - Charge Air Cooler: Efficiency Below Threshold - MIL ON]

* When found in a Touareg with the 3.0L TDI CNRB engine, there may be a firmware update for this:

Jef: /* Special Notes */

__FORCETOC__
== 01826 - Sensor for Steering Angle (G85); Supply Voltage Terminal 30 ==

==== Possible Symptoms ====

* Malfunction Indicator Light (MIL) active

==== Possible Causes ====

* Temporary Supply Voltage Interruption
* Steering Angle Sensor (G85) faulty
* Steering Column Control Module (J527) faulty

==== Possible Solutions ====

* Perform Steering Angle Sensor (G85) Adaptation
** See Vehicle specific [[Diagnostic Procedures]] for Details
* Check/Replace Steering Angle Sensor (G85)
* Check/Replace Steering Column Control Module (J527)

==== Special Notes ====

* When found in Audi A4/S4/RS4/Cabriolet (8E/8H): Brake Electronics, these are the most likely causes if the Basic Setting fails or the Fault comes back shortly after clearing. See TPI 0984403 for further details.
** MY 2001: Steering Column Control Module (J527) was the most common fault
** MY 2002: Steering Angle Sensor (G85) was the most common fault
** MY 2003/2004: Experience has shown the Steering Angle Sensor (G85) were the only cause, Steering Column Control Module (J527) were not defective yet.
** MY 2006/2007: Steering Column Control Module (J527) was the most common fault
* In many cases this code can be cleared out by a simple test drive
** Do several figure 8 turns (lock to lock) in a safe area
** Short road test, 0.5km
** Again, do figure 8 turns (lock to lock) in a safe area
** Follow up with another short road test, 0.5km
