Not sure if it is exactly the same but generally speaking this may help. You can also look easily online for hands on instructions. FIRST as always disconnect the negative on your battery. On my 90 VW Passat there are a total of 4 bolts that hold the alternator in place. Two at the top left which are associated with the slotted metal bar and two at the bottom (right and left) which allow the alternator to pivot back and forth along the slotted bar. Loosen the bottom two bolts then slowly the top bolt, do not remove any yet. Now if necessary slowly rotate/pivot the alternator loose. Now remove belt then all three bolts, then all small connectors on back of alternator as well (usually 3, label them if neccesary). Note you will need some long box mm wrench's to reach the bottom bolts. Keep all bolts and nuts and first inspect new alternator to make sure the old and new are the same. To replace follow the steps in reverse, ensuring little slack in tension.

When a started malefactions on a 1998 VW Passat the solenoid will make a clicking noise but the engine will not turn-over. To replace the unit remove the two bolts mounting the part onto the transmission.
