I was under the impression the apr fuel pump is one of the best. oh well, if it goes bang al have to invest in a Loba.

Mine struggled with similar issues. Bought a new battery and it worked even though battery test showed my existing battery seemed fine.
Also as good practice I now turn the key over halfway until the lights come on. Wait about 3 seconds until the lights go off and then I turn the key fully and even in the cold the car now starts perfect.
It used to judder a bit before I did this.

I bought a new battery from vw - it did improve the engine starting as before it would really struggle to start but would still start even if it took a little longer. I usually do let the lights go off (im used to driving diesels). I think I was just in a rush when i recorded that video. Its not the pcv as i have checked it today. I think I will get the coilpacks changed. Iv seen people putting in r8 coilpacks - how are these different from the standard ones?

I've heard the red blue pink whatever don't mean squat regards better power as they are just newer than your worn ones :signLOL: whoever says different doesn't know what they are taking about. :ashamed:

Looks and sounds like the start is spinning well with plenty of juice there to turn it over so I'd rule out battery and starter motor.
Red coil packs are more for show than anything
Have you had VCDS plugged in to it to see if there's any faults stored?
