Hello together recently bought me a Subaru for the first time. Built. 94, 135 TKM, 2 l Legacy Turbo. Now I have two questions: 1. Is it normal that the initially usual “nails” do not disappear even after warm running of the engine? If not, what can I do (aditive is already inside)? 2. Various LED’s don’t work, or I’m not sure if LEDs are installed at all: rear disc switch, seat heating, main light switch, warning indicator. Question: what is this, it ka nn hardly be that all LED’s have given up the mind! Thanks for the help
