Alternator Bosch or OEM Volkswagen

i had the same exact problem. tested the battery and alternator, both tested good. came across a fanactic VW mechanic. told him my problem, he test drove it for a couple of minutes. then he told me it was my alternator. my alternator is going bad. so i took his advise, bought a new bosch, and now, new more red light. plus the new alternator seemed to give me more power, thats from what i feel. probably just my imagination.

well i need a alternator because my bearing is about to fail and my buddy is selling me a BRAND NEW bosch unit for 50 bucks so why not...

I got a bosch when mine died on me. No complaints :thumbup:

my alternator is of the clutched variety. Its from a 1997 and will not contribute to the crank nose keyway issue. 90A Bosch $35 plus shipping

My 93 vw cabriolet is running an oem alternator from the factory.

I had to fit a new alternator since the old one had died on me: I replaced the non-original alternator with a bosch 90A alternator OEM VW/AUDI. It got up to 13.9volts now, the regulator limits it to 14V.

I ran the Toywagen with the waterpump and the crank. PS is only with the crank. I had to use a MK3 v-belt PS pulley for the waterpump as the stock one didn't align for some obscure reason. I have one of those aftermarket Bosch alts, so I had to put 2 washers to space the toyagen even more

Yeah I just bought a bosch too and it was too wide also I had to hacksaw a mm off to get it to fit in my bracket.

alright guys...i charged the battery and it started right up...put my meter on the batter with it running and it just kept going down in voltage over a 10 min span...so i would say the alt is bad...

I had a Bosch reman that self-machined itself to pieces in less than a year on my street car - the car that rarely saw more than 5K rpms. The Bosch replacement seemed to work OK but I sold the car shortly thereafter.
