Thanks for that, have just sent him a pm

The y shaped breather pipe on mine from the cam cover was split, have resealed it, was like this when i got the car last week and was driving fine then with original map on it. I thought this was just a oil breather pipe and not a vac pipe?? Any ideas for price or part number of this pipe as it may be the cause when putting more boost through the pipe work?? The map was a slight increase in boost approx 10% as didnt want to push the car too much as its getting old lol

Where did you get the diagram so you could remove most of the vac pipes from? Where did you get the catch tank from any pictures of the install

Have just flashed the original map back on to the car, now running fin all be it slower lol No fault codes stored great. Poss the remap is causing the n75 to operate out of tollerence causing the limp mode? Almost certain no pipes can be at fault as they would show up when im driving it with the original map on it. Might get the boost pressure turned down slightly on the remap and try it from there, could also be the n75 valve needing replaced if i am running higher boost? Was looking at the n75 j version not the original n75?

Going to get the logs with vagcom on way to work will let me see whats going on, will start to get bothered when i run out of things to check lol, got loads to check before i get to the stage of letting it go on fire

I think it will go for the original map on first as it was fine until it was mapped, could be the remap runing slighty more boost causing an old pipe to split but hope not as it seem a nightmare trying to trace which pipe is split and leaking, have ordered new boost/vac pipes anyway graet fun

I will just need to dig my magic wond out lol, it will be getting sold if i cant cure it

Yes it does seem a bit of a nightmate lol, might put the original map back on and run it see what happens, this will be easier to start with rather than looking for a needle ina haystack, thanks for the tips will update the progress i make or dont make lol.

Thanks for that will check tomorrow, ps i drove the car 5 miles from switching it off and restarting and it drove fine even under hard acceleration, if the pipes were split etc surely i would hear this clearly when boosting as the pressure would be escaping ?

Will do but it does seem like an electrical fault as when switching engine off the back on it returns to normal, cant hear any leaks, boost pipes being split etc, as far as i can remember it was fine before the remap

Yes spot on m8, that does look like the code i had, what are you thinking?

Has anyone has similar fault. Start veihcle up drive as normal full boost no engine managment light on, then after approx 6 mile there isnt any boost, switch engine off restart back to normal full boost again. Did notice there is a slight hesitation when lightly accelerating. not a misfire as just replaced coil packs and plugs as they went down. Vehicle has been remapped so have replaced the divertor valve, ws thinking the n75 valve might be on way out ??? Is it worth getting the n75 j valve as this may run better with the car being remapped??? Have checked the fault think it said boost fault between turbo and throttle!! Any would be great
