Power loss diag update - snow button So I have come across something that seems to have fixed the very slow responsiveness of the throttle in my series 1 RS4 auto today. I met up with the local stagea owners over the weekend and I heard at some point that the snow button on the centre console pressurizes the Atessa system when it is flicked on. So I thought that maybe in my car it is not pressurizing correctly upon ignition and that might be why the car feels so sluggish. I tried it this morning I flicked the switch to "snow" and back to "power" a couple of times and there it was: torque, accelleration, response. I can now feel the difference between off boost and on boost more defined and the wheels spin much easier too. So is there any info you guys might have or know of about how the "pressurizing" of the Atessa system works? Should I get the awd serviced maybe?

R33 Rb25det not performing New to the forums not really sure if this is the right section to be posting in but I've spent several hours raiding the forums and can't find a solution anywhere. I have an r33 rb25det it has a bigger fuel pump, front mount intercooler, super spark coils pack, 3.5" turbo back exhuast and a boost tee. It's running 0.74 bar of boost but it feels like it's not even boosting I can hear the turbo working and the gauges are reading 0.74 bar of boost. It smells like it's running real rich and has recently started to really chew through fuel. I have changed the spark plugs had them gapped correctly and the coil packs are 2 months old. What could be causing it to feel like it's not on boost and being real slow?
