Alternator Denso or OEM Volkswagen

Denso or nothing. You'll be doing this again in about 2 years if you chose poorly.

I went with Denso Reman for my choice. 2 years so far and no issue.

My auto shop is replacing the alternator on my 2013 Sienna for $657 with a DENSO part which is the only brand you should be using IMO.

Put the desno in fixed all my problems

Just bought one better denso at the auto parts store last year, was a 20min install, btw need to remove the rf tire and plastic to easily access as well as the bottom plates. Imo nice solid car and needs a decent part.

Denso is the OE for Land Rover.

Denso for sure, will last as long as the original, I think 20 years was a good life. The no name and parts store brand ones almost always fail shortly after install

Replaced the alternator - twice. The second one failed as a result of a jump start scorching a relay in the voltage :-( Replaced the starter (in 2024), First alternator failed at 49K miles - oddly, when the car came out of the shop, the oil light came on and they found debris in the pick up so I got a new long block (under warranty so I suspect VOA knew of some defect for that model/year). Had one strut bearing fail at about 90K miles. I also had the AC recharged - car actually came from the factory with too much pressure (would ice up on humid days). I've stuck to dealer maintenance for everything except the strut repair and the usual annual CC alignments (well documented issue...) and keep all fluids (coolant/brakes/DSG) fresh. My car is still a daily driver - I'm probably due another battery soon but it runs great. I'm tempted to freshen the struts and control arms and add a rear sway bar - and possibly a tune, but I also see a Golf R in my future! I've run 3 other cars to 250K miles (Volvo 850, Highlander and an Audi 4KQ) and I don't see any reason why the dub can't get to 200K+ particularly if you keep up with a full maintenance plan. You may need to have some carbon blasting done at 100K, have the timing chain tension and service the PCV (leaving that too long leads to the carbon build up in the DI engines) but those are like 50K mile intervals

The alternator (new OEM Denso, 2nd one, installed about 100kmi ago) on my wife's 2007 Solara v6 3MZFE with 227kmi just died last night. She didn't make it home.

I bought reman denso 2 years ago and it lasted 1 year.
