OK I need help. My car has just thrown a code P2074. Has anyone seen this before? The car will no longer hold boost but will idle fine.
Any ideas?
The car has only 2700 miles on it!

Are the mods listed in your sig the only mods you have?
I just did a little searching and it appears that code is often set overboosting under part throttle if you have an aftermarket wga. Could be something else also I guess.
Reset the computer and see if it comes back...

Yeah, I use to throw the part throttle over boost when I had my WGA and Boost Controller. All I did was disconnected the red line that attaches to the Upper Intercooler Hose.

The mods listed are the only mods so far.
I am away from home on business right now (at Belvidere Assy Plant) so my son is looking after the car for me. He found some info on-line about a vacuum hose by the turbo. He managed to get his hand in the area and found a slightly lose but still connected vacuum. He pushed it all the way home and now the car appears to be running right, the light took a few miles of driving before going out. We have it booked into the dealers for next Tuesday just in case the issue returns!
Has anyone had vacuum hose issues? I have already had to replace the vacuum coupling on top of the cylinder head due to it splitting in half!

Vac lines will often blow off especially when you start upping the boost. It's recommended, and is even part of the s2 install, to zip tie all vac lines.

As soon as I get home I will go around and zip-tie all the lines. I am planning stage 2 in the future so I will just get a jump on this part of the install!
Thank you for your help, much appreciated.
