Been running a Chipwerk Pro Stage 2 for about a year. Just got a CEL. VCDS shows these two DTCs. I'm going to clear them and drive it as usual tomorrow (single parent this week while the wife is out of town and the yard needs mowed). Seems odd to pop up now.
I thought something had gone bad with the DSG as the car started to shift very differently.

The way the CW operates is by messing with the boost signals/reading, so it makes sense. Anyway, I wouldn't give it a second thought unless the codes pop up again.

Fingers crossed. I plan on going with a tune soon but am saving my $100 bills. I was going to say pennies, but then Audi tax.

So the CEL didn't come back on but the car is not shifting right. I keep the car in dynamic mode and it is no longer blipping the throttle when slowing down. It is not very responsive to my manual input on the paddle shifters either. Shit.

Easy way to start your process of elimination is to disconnect your Chipwerke module and run without it... See if that changes anything.

Same codes came back on my 2nd drive of the day. I'll certainly now start with disconnecting the Chipwerk.

Well, that embarrassing. The connector to the CW box itself had worked loose. Time for a zip tie.
