I do have a button like the one described, but mine has a picture of a fan on it, i thought that might be for the rear air con of something? What does a winter pack do anhway?
AS for the power loos il tell you all the story from start to fin in a nutshell:
A few weeks earlier, i had a full service, everything was fine thena week later a loss of power occured, no turo and only revvs up to 1000, so i did almost 5mph all the way to the garage. When i got there, we couldnt figure out the problem, do he took off the fule filtler only to find it was full of CXXp. So replaced it, put purge stuff in the tank and ran the engine on high revvs for a little while and it seemed to clear, then everything was fine again. Until the following week whe my van wouldnt start all all, turned out he glow plug relay had gone, so put another one in.
Everything was fine again, but everytime i cold start now i get a juddering and whitesmoke, so last week i changed the glow plugs themselves, only to find the older ones where perfect. grrrrr
So now im at a loss, im going to start the van in a min, to see if i have that button and turn it off.
As for the air filter, its a new one only been in a few weeks.......
