ok well here these are the check engine codes that are coming up on my car, alot of the stuff i removed, maybe i have removed something i need u tell me. here they are:

20 – MOP
25 – solenoid valve (pressure regulator control (PRC))
26 – step motor (MOP)
30 – split air solenoid valve
31 – solenoid valve (relief)
32 – solenoid valve (switch)
33 – port air solenoid valve
34 – solenoid valve (bypass air control (bac))
38 – solenoid valve (accelerated warm-up system)
40 – auxiliary port valve
41 – solenoid valve (variable dynamic effect intake control (vdi))

I'm running a premix so i don't have the metering oil pump on there and i know it will run in limp mode or what ever its called, but anything else?

Hmm, does limp mode affect idle also?

Definetly a question an S5 guy is gonna have to answer...

Luke_Tech

i don't know thats what i'm asking

yeah some of what you removed is needed just to run the car properlly and for decent power.


why in the world would you remove the aux port and VDI actuation???

With everything removed like that you might as well just put a 12a in there and of course the car is in the limp mode.

And no BAC?? I guess you are not driving on the street and need air condition, rear defrost, headlights, etc???
