V70 BJ99 Car purchase Detail questions

Hello first time, since I’m new here in the forum I introduce myself briefly. My name is Jan, ’87 year of construction and come from the vicinity of Bielefeld (JA there really is!) I play with the thought to buy a ’99 V70 with 198tkm from a notorious Volvo driver. Except the usual flaws (art leather partial equipment is the face and the usual signs of wear, brake is still enough for about 3/4 year) he stands there. To the detail questions : As soon as one activates the brake pedal lights up an orange warning light with a pear symbol, lights are all as far as I have seen this i.O. –> hint of bigger problem? In the rear passenger door should actually be a “position light”, this has been expanded because the permant lights –> door contact or even what bigger is it? The disguise trunk flap is loose, has to save something like that follows: ~8tkm 2.5lPS switch is not available in winter time.
