Online manuals anywhere?
 

In the forum for one of my Japanese cars, a few guys got together and made the factory manuals for the older model available online.
I am trying to help out a friend with a strange problem and it would be very helpful if I could reference one for the 85ish Jetta.
Does anyone know where one of these might be online without having to buy the very expensive manual?
He is having the oil pressure beep beep even though the pressure is 38psi warm idle.
I would greatly appreciate any help you folks could offer.

Thanks much!
