Some DBW/VAG help please
no help in the A4 forums so I thought I would ask here. In searching I have a feeling block 006 might not be the same with the S, but in any case, I'm asking about the block which tells you when you are at idle/part throttle/overrun/enrich. TIA.
When I'm at idle I see idle, when I'm at part throttle I see it say part throttle. When I get off WOT throttle is says overrun. When I get on the throttle it says enrich, then about half a second later it says part throttle again until I let off. Even if I get full boost before putting the pedal to the floor I get part throttle. Is that right?

but should it stay on enrich when the pedal is on the floor?
I guess I'm getting at if I have the pedal on the floor and it says part throttle, am I going from closed to open loop?

Its been a while since I logged it but what you are describing sounds like what I saw.
Dunno if the part-throttle signifies open loop or not. If I have a chance I'll do another log and see if I can figure it out.

Open loop = adjusting AFR based on O2 sensors...
Closed loop = relying entirely on preprogrammed fuel maps.
Generally open loop happens at idle and part throttle and closed loop is at WOT.
