Couldn't find a video for this so i made one, it's made after since i was all covered in grease and fuel while doing it but you'll get the idea, hope it helps.
Sorry, totally forgot to explain that you can remove bottom screw after you pull the pump out of the engine and get it up slightly, then you can take the pump out completely.
Faults I had:
Fuel Pressure Regulator Valve (N276)
P2296 - 001 - Short to Plus - Intermittent - MIL ON
Fuel Rail/System Pressure
P0087 - 008 - Too Low - MIL ON
Random/Multiple Cylinder Misfire Detected
P0300 - 001 - - Intermittent - MIL ON
And also bunch of Cylinder misfires.
Here's link to check fuel pressure if you have VagCom:

Except for this car Group 230 was actually 231.
My pressure stayed at 6.5bar, which is what tank fuel pump creates i guess.
After fixing it was up in 35bar range.
