Would say there is a possible boost leak man, had a wee search and its either that or a sticking DV but seeing as youve just fittted the 008 id sya boost leak.

Could be leak. Faulty dump valve. Faulty maf, faulty n75, faulty n249 . Think that covers it.

well n249 is bypassed , would that throw up this code?? ( atm the box is still connected )

Dump valve holds pressure according to the liquid gauge so wouldnt have thought it was faulty?

n75 seems to work according to the liquid as well , when off throttle postion is at 0% when on throttle postion is at 95%?

Maf ... hmm how can i check the Maf? (havent had it on the liquid yet what should i be looking for on it??)

Try running air flow logs. See what your max is. A under reading maf will cause the fault code, been there done it.

just to add , told my mate this anyone get any info from this that could point me in a direction ?

'after clearing the code the first time when I started the car again , there was a loud noise from the exhaust and a sortoff bang then the engine was screaming its tits off as well as the exhaust shaking sort off as could feel it under the car if you know what I mean , I turned the car off then back on and the revs were rising up and went to about 2k then came back down , then the code was back, any ideas?'

The MAF reading is a bit low....have you unplugged it and gone for drive to see if things improve?

i have not nope , just unplug the plug , or remove it completly?

163 = about 203 bhp , which is also pretty low :/ , when i was reading my bhp on the gauge i was getting about 190 bhp ... which sucks

Just unplug the MAF and go for a drive , if it pulls better then you need a new MAF if it is horrible and feels worse then it is likely to be something else, I am having issues with my LCR too and it is getting to be a real joke now seeing as I have only had it 2 months!

right so on way home i went to basically redline it in 4th at about 100mph , and got 164 g/s on the Maf so that basically the max which is low ?

then coming into inverurie just before i my house , car felt sluggish checked n75 , was opening only to 5%? and also boost was max 6psi and once released at 10psi ? im guessing this is LIMP mode?? (which im not really sure what that it)

anyway why would my car have went into limp mode? because im sure my car does this quite a bit , as ive noticed it feeling sluggish quite a few times tbh ? :|

Can you hear a hissing noise from anywhere in the engine (other than the turbo?). When I popped a hose I lost most of the power and could hear air escaping. If you can't hear any leaks, I'd look at the MAF. The N249 Bypass won't through that code up, that'll show a 17608 and another one I can't remember, but not the one you mention (they both relate to solenoid and open circuits. I.e the N249 solenoid) :)

Just also thought, as mentioned ooop there ^^^ could be a leaking DV, but you'd hear that hissing too I think
