I just replaced the oil in both the trans and diff in my '90 200TQ (should
be exactly the same as your car).
The capacities are:
transmission--3.4 qts (3.2 l)
differential--2.3 qts (2.2 l)
Incidentally, I use Mobil 1 synthetic gear lube, 75W/90. I have made this
change on other quattros, and as expected, get better performance in the
depths of winter. Note that both the trans and diff have two drain plugs;
remove both, and you don't have to worry about putting the car on an
incline to completely drain the oil. In a related point, I use Mobil 1
5W/30 for engine oil in the winter and never have seen a problem with oil
pressure. Furthermore, the car starts more easily in below 0 temperatures.
