Boost Surging

[h100vw]

Okay so when i got home from work i unplugged the N75 Valve and measured the resistance which was 29.5 Ohms, which is just within the tolerances ive read about on the internet, however this won't prove that is working completely. As the problem only occurs during full throttle could this valve still be the issue as I know that the N75 runs of throttle position. I also removed the vac pipe from the DV and attached some tubing of my own and did the suck test, and it didn't loose vacuum.

So i got my tablet and using the torque pro app (I know its not as good as Vag-Com). Before going for a drive i had zero fault codes. After going off and giving it some beans, i got home and re scanned and had P0141 (02 Sensor Heater Circuit (Bank 1 Sensor 2)
Could this be the issue causing it to surge?

I also noticed that it spikes and holds boost on half throttle and only surges when you have your foot flat to the floor.

The heater fault isn't the problem.

You need VCDS or a way of logging multiple blocks at once. ME7logger will do this with an ebay VCDS cable.

I don't think there's anything wrong with the N75 either

Google that, I can send you one of the files you'll need to enable the logging to work for the Polo ECU.
