Oil light, pressure gauge and other

[Joshua Field]

Recently acquired a 1990 Coupe Quattro (and i am thrilled!) - and I've got 
a long list of things to deal with. #1 on the list is sorting out the 
warning i am getting. As i accelerate and hit about 3k RPM the oil warning 
light starts to beep and flash. (the little dripping oil can animation)

Also - the gauges aren't doing anything (oil pressure and oil temp). The 
pressure gauge reads all the way to the right and the temp is flat at the 
left. I am wondering if the sensor/sender is integrated with the dash 
warning or not.

Incidentally, the coolant temp gauge is dead as well. related? - i am 
guessing its only related in as much as its an Audi electronic part. :)

thanks for any help!
