Could it be the MAF????

I have noticed that the car is sluggish in the day when its hot/warm ie today 25c, but when it gets to about 9 10 at night when its 12 13c it has alot more power and there's more torque when you put your foot down? also seems to useing abit more fuel getting about 10mpg less, i was thinking it might be the maf?? has anybody had this before?

Fairly normal... hot air is less dense... makes turbo engines lathargic... ECU will compensate to a degree by upping boost to meet torque request

I would log airflow before coming to the conclusion that the MAF is tired tbh..

Cheers for the info, I found the problem today, there was a split in the pcv pipe, replaced it and has worked a treat more power back now and noticed the idle is a tad smoother to
