Cheers, it did end up being the exhaust turbo actuator. I tried lubing it but it didn't work. Ended up buying a new actuator

65plt 1.2 tsi 8v cbzb decides to lose power occasionally, ive also noticed mpg slightly less than usual. Garage suggested it could be the MAP sensors, so ive cleaned them with contact cleaner. When removing the one at the back of the engine it has no screws holding it in place! Ive had the car 5years so dont know why these would be missing, so not sure if they have never been there or have worked loose? And wether this might cause an issue? Turbo actuator has also been mentioned but thats a dear-do in replacing so hoping the MAP sensor cleaning does the job.
