5KT oil filter (was Oil change)

I have an '87 5KT (non-Q), which only uses 1 oil filter due to the 
water-cooling of the turbo as Glen pointed out.  It's also intercooled, BTW.
Is there a line running from the water-pump to the turbo and should you hear 
this cycling on for a fixed period whenever the engine is turned off?  On my 
other turbocharged car which also has a water-cooled turbo, the pump runs for 
30 secs every time the engine is switched off.  I don't hear this in the 5KT 
so I usually take it easy after getting off the highway to let the turbo wind 
down or let the car idle for a few minutes.

P.S. when did Audi start providing air-bags as a feature (std/optional)?
