Err well here it is the first code to pop on the problematic ctt P0234 overboost. Was driving to today and booted it a bit and felt flat to redline Wtf, almost like the variocam didn't switch to high lift because the boost gauge said +0.8 bar still as per spec. So I whipped out the trusty v-checker which is always in the temperamental Pig in case, and it shows the P0234 code. I know the possible causes and have read a lot of posts of this code but not found any with fixes except loose piping broken piping which at the moment I'm thinking I don't have any (all bloody new).

Hey guys, I'm trying to figure out an issue in my TT. Boost delivery isn't as smooth as it used to be. Under constant throttle application (lets say half throttle) boost will hold at .4bar for a number of seconds when it should really be building up, and then all of a sudden it jumps up to 1.2bar and takes off. Occationally it will jump up to 1.5 bar and hold until I let off (I don't hold it for long, and I try to avoid this). I've got an EPL K16 flash set for 1.2 bar, so 1.5 is overboosting. And then, sometimes I just can't get up to the 1.2 bar...it will max out at .8-.9 occationally. So fa
