I've had a bunch of trouble with my new car(Dacia Dokker, bought in Janury), mostly because the garage people are idiots/assholes.
After the latest problem I found the following part lying loose under the back chairs and we also found a plastic nut(the type that also holds the jack in place in the back) in the back wich we can't find the source for.
Codes on the inside are
85042 5283 R Mp6818
But these don't give me anything relevant on google. I want to know what this is so the garage can't make up anymore bullshit.
