[s-cars] An A/C question

[Ian Duff]

According to Mr Bentley, page 87-126, for an R-134a system, he's right:
"Only a high pressure service valve is used for A/C system servicing. A low
pressure service valve is not installed in the A/C system. Perform all A/C
system service operations (i.e. discharging, evacuating, and charging)
through the high pressure service valve only."

According to a friend of mine who is a Audi/Porsche master mechanic there is
NO low side port on the S4 AC system. The freon must be forced in with the
vehicle off, you can't top it off with a can, etc.
