I have a 2007 s6 that I’m trying to sort out. I purchased it from a dealership (not an Audi dealer) that did a hack job putting the car back together after a small fire. Todays adventure was tracking down where a vacuum line that was taped off. The line is run between the fans and front of the motor and is hanging open on the passenger side of the engine bay. I haven’t been able to find anything missing a vac line. I found a vacuum line parts diagram on line and noticed a line that looks like the one Im trying to find a home for going to a vacuum reservoir. I can’t find the reservoir listed for the s6 anywhere on my car. I do however see a big (or at least big for this car) empty space on the passenger side under the headlight where the line is pointing. Is this where the reservoir goes? Nearly all the damage to the car was in this area so it’s not hard for me to believe a plastic bottle could have melted. Thanks for any help you can provide.
