Interesting. In the US, Audis generally get no respect from the public at
large. They're percieved as expensive, slow, fragile cars for weirdos. And
given the way Audi built cars for this market and the models they chose
to import, I can't blame the american public 100%. The A4 is starting win
people over, but it might just be that I live near Boston now. European
cars are popular in new england. In the American midwest, Audis are
frequently reported as UFOs.

Hmmm. I didn't know you could do that. That does make it sound kinda cool.
I gotta get me a Coupe with a digital dash and see how I like it. The Coupe
dash is green, though. Yours is orange, right?

That's it. It's a little grey box attached to the fuel distributor with 2
screws. It has a 2-prong plug on it. In the older US models, this valve was
plumbed into the fuel lines separately and resides back between the fuel dist
and the strut mount. The ECU in the US model interprets the OXS voltage and
uses this valve to constantly trim the control pressure so the engine is
running stoich all the time (except for warmup and full throttle). At some
point, the old style freq valve was dropped in favor of the newer grey box
style. The function remains the same. In the US models, the ECU also used
the freq valve to play with the control pressure during warmup. It looks
like Audi implemented this in the Euro models in '88. Cool. They worked out
all the bugs in the US market, believe me. So your ECU, unlike the ECU from
a WR engine car, has a couple fuel curves. See, WR engine cars have no way
to let the computer affect the car's fueling. The MB engine does, thanks to
the freq valve implemented for the US market. That's why you have the hat-
shaped fuel pressure dampers, by the way. they make the flow of fuel to
the fuel dist very smooth, so the freq valve doesn't have to fight uneven
fuel flow.

Tell me about it. I've gone to great lengths to put my car (an '85) back
to the way it should be. Kim Collins of Quattro Sports (Sussex?) provided
me a set of "real" bumpers, I've installed the good lights, the engine's
got most of it's power back, and the box sections are coming out of the
trunk VERY soon. I'm going to be back in touch with him soon for a cam,
blacked-out taillight lenses (another omission from the US market), and
maybe a fuel dist and computer. At least Audi made it easy to put everything
back.
One quick final question: The switches on the left side of the instrument
pod - the top control is the headlight switch, and the bottom is the
panel brightness. From top to bottom, what are the other two switches?
Later,
