Ah your 2nd post we were expecting, hope you are enjoying the P12 apart from this episode of course. It sounds like one of the the MAF's (Mass Air flow Sensors) one on the air filter housing the other on the exhaust side. With care and gentle treatment they can be cleaned and allowed to dry with carb cleaner. They are delicate so don't hold the spray to close (10 2) the aim is to allow the cleaner onto the film to do its work not blast the thing clean. You will need a security torx to get it off. If that does not work the faulty one will have to be replaced. I believe they are interchangeable. but you ought to check, they are not cheap either.

yes defo sounds like MAF problem, as for the windows, they don't like the ice. If they are stuck and you try to open them, there is a small clip which breaks. This can be replaced but often the cables come away at the same time so the whole motor unit may need replaced!!!

Well There are two mafs on the p12 which believe are interchangeable, So the one you took off must be working, I assume the one you put on is working so swap the one on the exhaust side with the one you took off and see what happens
