You can test the injectors in VCDS. There is a TSB somewhere..
After an overnight stationary period drive the vehicle with cold engine between 1200 - 1600 rpm till the complaint occurs. Constantly read the measured value block 13 and 14 for the smooth running control in the engine control unit. The values of one or several cylinders should noticeably move to positive.
modified injectors A8: with 3.0l, 4.2l TDI from: WAUZZZ4E*7N016685
Replace the injector with the highest deviation and all injectors produced between 1.3.2006 and 30.4.2006.
Example of production date: 060304 stands for 4.3.2006
vcds go to address 01 measured values below
013 Smooth running control
1)Cyl. 1 Injection quantity variation
[mg/stroke]
2)Cyl. 2 Injection quantity variation
[mg/stroke]
3)Cyl. 3 Injection quantity variation
[mg/stroke]
4) Vacant
Permissible values at idle: +- 2,99 mg/stroke
A If the permissible tolerance is exceeded
first check injector IQA-IVA adaption values
014 Smooth running control
1)Cyl. 4 Injection quantity variation
[mg/stroke]
2)Cyl. 5 Injection quantity variation
[mg/stroke]
3)Cyl. 6 Injection quantity variation
[mg/stroke]
4) Vacant
Permissible values at idle: +- 2,99 mg/stroke
A If the permissible tolerance is exceeded
first check injector IQA-IVA adaption values
015 Fuel consumption
1) Engine speed
[rpm]
2) Injection quantity
[mg/stroke]
3) Fuel consumption
[ltr/h]
4) Engine torque specification
[Nm] Driver input via accelerator pedal
I replaced mine with later ones EU5 ones, but not the very later ones for 4 digit engine code cars.I used the later ones as they were cheaper.
