1997 Aero.
My boost gauge wasn't working when I picked up the car last weekend.
I assumed the vacuum hose had popped off the gauge, so performed a test. I located the vacuum hose that goes into the false firewall (right between the flow and return hoses for the heater) and disconnected the hose from the T piece. I then connected a piece of hose via a vacuum hose connector to the hose that disappeared into the firewall and blew through it. My son was sat in the car and said he could hear a hissing sound and I felt little resistance to the air I was blowing through it, so clearly a hose was loose somewhere.
so being a bit daunted by the idea of taking the top of the dash off to gain access to the back of the gauge, I removed the panel where the pedals go into and could see the hose, but when I gave it a gentle tug it felt firmly held, ie attached. Weird.
I posted a question about how to get to the back of the gauge without taking the dash op off and "fellow Saaber" came up trumps by suggesting that it may have popped off in the Aquarium (the Aquarium is under the long plastic strip at the base of the windscreen/Windshield that the washer hoses disappear into)Sure enough, there is a white vacuum hose nipple sticking out of the real firewall with my hose popped right off it. The hose was perished anyway, so I replaced it with some nice new red hose that I have just finished dressing the engine with. (While I was in there, I lubed the windscreen wiper mechanism and checked the ventilation filter, which looked like it had been ventilating a coal mine it was so thick with black soot!)
Rather than re-use the rather brittle T-piece, I decided to run the new hose to the extra vacuum nipple on the back of the throttle body.
Gauge is now fine, windscreen wipers have lost the annoying squeek and I have much better ventilation.
Not a bad evening's work!
Hope this helps someone one day
