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.

enter image description here enter image description here enter image description here

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.

  • Hmm well it looks plastic to me so I would think it isnt anything too mechanically important. Curious to see if anyone knows! Commented Jul 22, 2017 at 0:59
  • What work was done?

  • My blinkers weren't working and they said the problem had to do with the cabling at the tow hook. That's all I know.

  • Could it be a cover / protector for the end of a seat rail or edge of a fokding seat or rear seat catch?

  • Oh and they also replaced the AC because it wasn't working(forgot because that problem was noticed 2 months ago already) I'm currently checking anything I can too see if anything's missing in the engine or anywhere else ....

Looks like a bumper mounting bracket. Not sure if it's front or rear.

Google image search for 850425283R

Google image search for 850425283R

Some Russian auto parts site has BRKTMTG RR BMPR (Bracket Mount Rear Bumper?) in a description for it.


And finally here is Ukrainian classified ad, which lists it as right front bumper fastening bracket (Кронштейн крепления бампера правый передний) for Renault (Dacia) Duster.

  • ugh, from the way the codes were printed I thought 85042 and 5283 R were 2 different codes, now I feel like a dumbass. Too bad all the sites are in slavic languages but at least now I know it's part of the bumper and know where to look.

    And googling the code in the format of your picture of the original renault bag I found a page where they specify its location: apc.onwheels.ru/… (part nr 19) , Now I'm gonna check in the morning if they just forgot about it or maybe put in another one and this was a spart part of sorts they left behind.
