I read about modifying the EGR duty cycle and the amount of fuel going to the engine on another Audi forum so tried this today with the aim of reducing the amount of black smoke and dirtying on the EGR and intake manifold by reducing the EGR to it's minimum setting.
The values I changed are found and modified by going into 01 Engine in vag-com, login using 12233 and in adaption, looking at channel 01, 02 and 03
01 is apparently the fuel quantity, 02 the idle setting and 03 the EGR cycle
All three were set to 32768 on mine, so I changed 01 to 32784 and 03 to 33638.
Now the car just seemed a little more pokier on accelerating, the midrange seemed improved to me, I even had an S3 on the slip road onto the M40 earlier!
I need some time to monitor the black smoke, fingers crossed it will be reduced.
