Several questions about the Focus II Trend Tournament 1.6 TDCi

Guude ihr Leud, last week i buried my Fiesta MK III 1,3l with the recycler and decided for an annual car of the above type. But now i have some questions about the focus, because i am still mentally strongly fiestarized. And these are “only minor” different*gg* So, point one would be the trunk lock, it has happened to me now 3 times that i am standing at the traffic light and my trunk has unlocked by ghost hand. Is there an explanation for this? I don’t want to have that on the highway. Luckily it only happened in the stand, but it stops the traffic. Point two. Since the focus is already beyond the 25,000 km, I wanted to animate it, of course only warm driven, sometimes to the maximum performance, however, it has from 130 only badly accelerated. At the driving destination I looked at the air filter once and found it strongly augmented. I would like to know if it is really only the air filter, which will be tomorrow l changed, or can there be more? There was no message in the on-board computer and no message about a lamp in the amature board. Point three. Sounds stupid now, but do I get the matching warning triangle only at Ford, or is there any other dealer for? My previous warning triangle is about twice as big as the trimming in the trunk floor pretends. And I hate nothing more than when something stupid is fooling around in the trunk. Greeting Alexander
