I just had to swap my alternator today on my MK7. Mine was Valeo but I could only find a Bosch locally, I decided to give it a shot and it worked just fine. Just a PSA for anyone in the same situation, they are both the same barring a slightly different orientation of the plug on the back.
I just had to replace original alternator in my 213k mile 2017.
I legit daily drive an 03 camry, the only thing that needed changing in my 2 years of owning it was the alternator.
For any other car it would be replace but it's a Camry, those items especially water pump and alternator generally needs replacing at 220k but as long as you replace them with OEM Toyota parts you'll be good for years to come.
I am currently leaning towards picking up a new Bosch 120 amp over the BMW.
I\u2019m 43 and only have had 3 cars in my life only Corollas and Camry. I get a new one around 250k miles. They are great reliable cars that run well with basic maintenance. Only wear and tear items have I ever replaced with the exception of an alternateer on one of my corollas at around 200k miles. As long as I can keep going to 250k I will keep buying them.
My last OEM Toyota alternator made it to 250K miles. My future non-Toyota ones failed because they were cheap remanufactured ones and later I found a failing harmonic balancer that was putting extra pressure on bearings of the alternator
Did this years ago in my 5th gen, not because of more Amps, but because for some dumb reason the Alternator for the Celica was $250 reman (back in 2014), but Camry's in the Junk yard with Good OEM Alternators were plentiful. That was after I had 3 reman alternators fail in less than 6 months, 2 being DOA!
Literally just put a FCP Bosch remanufactured 2 pin alternator in our 530 last week--it doesn't work at all. Communicating with FCP currently to send it back and get a replacement, but I'm not happy about it. I was told that Bosch was the one to go with for best quality, but now I'm skeptical.
the bosch alternators are junk. I had to warranty mine through fcp 3 times for the exact same bs: loud ass whining noise and over volting immediately after instal. Cheap chinese junk.
