Special Functions

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.

• 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.
    

Particle Filter Emergency Regeneration

Prerequisites:

• Ignition ON
• Engine ON (Idle)
• Oil Temperature above 70 °C (see MVB 007.2)
• Particle Filter Load below ???g (see MVB 105.3 for Bank 1 & MVB 106.3 for Bank 2)
  • If the Particle Filter Load is above ???g 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.
