Newbie here so hope I am posting right... So here goes I have a 2004 fabia vrs front mount intercooler 160cc injectors stage 2 remap upgrade turbo etc etc, if been using your forum and previous members help for days I originally had no boost and fault code 17564 so I rewired the map sensor all the way back to pin 71 and 31 on the ecu, I have now got rid of code 17564 which if memory serves me was map sensor earth to ground, now I have code 18000 I cannot clear the code even with the engine not running so leads me to believe it's not a turbo issue I have cleaned the earths under where the original air filter sat but now I'm lost. Also I made a school boy error when fiddling and removed all the pipes off the vacuum box on the drivers side wing I think it put them back the right way but does anyone have a diagram or such like just so I can be 100%? please help am I missing something all positive input much appreciated!

The actual code is 18000/p1592 altitude sensor/ boost pressure sensor implausible correlation. Thanks
