Alternator OEM KIA or Bosch
I have a 2013 Soul !. Got it about 2 years ago. Very reliable, only had one issue and that was the alternator going out on me a few weeks ago. 182k miles on it. It doesn\u2019t consume oil at the same pace others mention. It does currently idle a little rough, but Not terribly.
*Hella* is €216 to €380, *Bosch* is €212 to €432. Location: Germany, "*autodoc"* website
I've got the flickering lights so I'm going between the Denso reman and Bosch reman. Looks like the Bosch reman is done in house and the germans have pretty good engineering imo.
I recently replaced my alternator on one car w/a new Bosch unit. Cost about $200 and took me a couple of hours. Dealer cost just for the part was $700 and with book time they priced it out at over $1,400.
Bosch Alternators have 2 posts on them, the big one is for main battery ground, the smaller one is for the exciter or blue wire. When the cars ignition switch is turned on, the Dash light (led and diode) applies 12V+ to the coils to excite them, so the alternator can produce a charge. When the Alternator is producing current and voltage it goes to 13.5-14Volts.
The part # for the Alternator (Automatic trans) is 6H903016L and it's made by Bosh. [Europaparts](https://parts.audiusa.com/p/Audi_2012_A4-Base-Sedan-20L-AT-Quattro/Alternator/48001649/06H903016L.html) sell's it for $499.95 (OEM).
I replaced the battery, and upgraded to an AGM battery while I was at it. The problem still wasn’t solved though.
I order a Bosch AL113MX Reman Alternator (yep Bosch reman the Motorola) since that was what was currently in there. The 81 has a big square York compressor mounted right on top of the alternator which means that to get the rear alternator bolt you better have the right extensions and you are going to do it blind. So after at lot of effort I got the old alternator out and the new one in and only then did I notice that the pulley did not line up.
Alternator and the battery are overpriced 2x (google replacement Varta battery and smth like Bosch alternator for your car on pkwteile or idealo).
I bought a brand new, OEM Bosch alternator from Rock Auto. A week back I started noticing a bearing squeak sound in the engine on startup... Later got another battery light... Today was driving and lost power steering suddenly and got battery light again. Pulled over as the car was getting hot quickly. Opened the hood and the serpentine belt was shredded. Alternator was completely seized and had burnt belt on the pulley. Got it towed home.
