Hey everyone, I’m new here, I have a 1995 Audi A6 Quattro, it’s a 5 speed manual, so I just got this Audi last Sunday and it was missing some things so I’ve been going through replacing and fixing issues, but on the passenger side head to the rear of it, there is an area that is clearly supposed to have something bolted to it but I can’t figure out what it is, I saw a diagram somewhere and it said it was supposed
to be a vacuum pump, I cannot find this part anywhere or find any other info on what is supposed to be there. I know a little about cars but I’m far from a mechanic, if anyone could help I would greatly appreciate it
