I've been having this problem ever since i bought this car, since then ive acquired a vag-com and was able to find out what the computer was saying.
the car is completely stock...

Since seeing this trouble code I have:
-Pressure tested the boost system (held to 20 PSI)
-Checked the DV with the finger-suction method
-Cleaned the intercooler and MAP sensor
-Cleaned the MAF
-Replaced all coil packs
-Bypassed the n249
-Replaced the n75 (runs better but still throws the code when getting on freeway)

I have NO IDEA which direction to head now.....any help would be greatly appreciated

thanks
