I own a rio 2013. di ko gets bat marami parin nagsabi ng walang parts available sa kia e nasa shopee lang lahat. madali lang rin ayusin, naka DIY na ako nagpalit ng alternator, clock spring, ignition coils at eps motor. halos lahat ng fix nasa youtube lang.

Pros: parts available, easy to repair
Vehicle: Kia Rio

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.

Pros: worked just fine, compatible

In place of the Valeo alternator I installed a Bosch VR6 120 amp alternator with a Bosch ABA alternator pulley (its 5 ribs versus 6 ribs of the VR6).

Pros: increased amperage

I just went over 195,000 miles while I've driven it over 26,000 miles this year with the only failures being the original 15 year old Bosch alternator and the spark plugs needing to be replaced.

Pros: motor itself is reliable
Cons: alternator needed replacement
Mileage: 313821 km

I had an 08 Rio that I bought used in 2011 barely used. It was good for a couple of years but once things started to go it was one thing after another. Alternator twice, the starter.

Pros: good for a couple years
Cons: alternator failed twice
Vehicle: Kia Rio

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.

Cons: doesn't work at all
Vehicle: BMW

Cons: loud whining noise, over volting
