Owner reviews for alternator

I would try replacing it with a stock Bosch alternator.

Between the two that I've owned, I have way over 250k miles in 'em and they are awesome vehicles. Maintenance has been very reasonable although we just had to put a new alternator in the one we have now.

I ordered an alternator with code 07C903021N (Hitachi LR1190-907E) and I hope it is the right one, because there are many versions and the all look the same, except for the position of the B+ post and the DFM terminal connector with respect to the orientation of the cooling tubes.

Got it. So am I correct in thinking that these Bosch alternators have both diodes to get to DC and voltage regulators to make it a clean voltage?

Welp... the alternator AND the battery are dead. New battery is in, now to do the alternator but I need food first. I was amazed that the store had a rebuilt Bosch alternator IN STOCK

My 05' Golf TDI came with a Bosch unit from the factory and lasted about 90k or so, I replaced it with a Bosch Reman and its been doing well, 120k now.

I got an OEM (Bosch) new replacement 120A alternator from German Auto Parts. It came with the pulley installed.

I recently replaced my alternator with a new Bosch. It has been running fine now for about 300 miles. Now however my alternator light is coming on.

My mom had a 93 Lumina Euro sedan with the 3.8. The only real serious issue it had was a failed alternator which drained the battery and almost left me stranded one night because the headlights dimmed to the point of being unusable. Other than that, yes the alignment was poor and it had some bad brake wear and warping of the rotors.

My Rabbit's alternator lasted a solid 40,000 miles!
