      My suggestion is to replace the Denso unit with a Denso unit. I've had very good experiences with Denso, including a variety of electrical components, so I (personally) don't think there's an advantage to the Bosch unit. Instead, you could (potentially) send the wrong voltage straight to the ECU and cause god-knows-what. If there's one thing about Volvo's, it's that they are SENS-I-TIVE to voltage. I strongly suggest you check Denso's website at http://densoautoparts.com/find-my-pa...icle-selection and at least source one out near you to get a complete cost/benefit analysis.

      That being said, if you do get the Bosch and it works... lets us know!

      Ugh, why so confusing?

      The Denso website shows a 2005 S40 as 210-0764, and a 2006 S40 as 210-0764 or 210-0841. Just for grins I put in 2004 and got the different motor selection for gen1 and gen 2 cars, chose the 2.5 T5 and got another number, 210-0843 !

      Upon closer inspection on FCP's website they show the 2005 being a Bosch AL7673X, and the 2006 as a Bosch AL9436X.

      Only iPd shows a more more precise VIN breakdown with the AL7673X being for 2004.5 thru part of 2005, then the AL9436X for the rest of 2005 through 2007, but who knows if they're right?

      It's almost like that VIN break in 2005 confuses these suppliers or something. Another example, RockAuto only lists Bosch for 2005 the AL7673X, then for 2006 only the Denso 210-0764.

      I dunno, so many discrepancies for us 2005 owners it seems. By the way, the label on my car says it was manufactured 09/2004.

      So what is it about the Bosch alternator that doesn't work? Is just that my female harness connector simply won't physically push down on the male connector block even though they're both 3-pin? Or is it because of the wiring mystery? I really would have no way of knowing which pin on the Bosch leads to the ECM, I only know that it's the middle pin on my harness that appears to run to the ECM and the other two are jumpered together.

      Edit: Bennett Auto Supply shows up as the Denso supplier in my area. I will give them a call tomorrow.

      Because the Denso and Bosch units are wired differently.

      I had the same question about my alternator (see above). If your current alternator is a FoMoCo 3M5T-10300-SD, then Denso alternator part#2100764 is the right part. Promise.

      Based on my vin (last 6 digits), the alternator for my car falls in the middle. This price for it from tasca is $443 + $50 core. Searching for that part number shows that the Bosch AL9436X might be a replacement for $300 cheaper. I need to a little more research before going that route.

      Here's the Denso sticker off my alternator ... notice the Volvo part number 30667103



      Here's the VIDA screenshot using my car/VIN ...



      So, VIDA is saying that 36001463 is the correct part number for chassis numbers 45204-250052 and that it's an exchange for (among others) part number 30667103.

      If the Bosch alternator is wrong, mis-wired, or otherwise won't work then why do all these reputable part supplier's cross reference the AL9436X with the Volvo part number 36001463?

      You are down to the correct chassis split stuff now.

      As for Bosch... Several years back Volvo sent out a Tech Bulletin (Sorry, I no longer have access to it). It basically said they were having short term supply issues with replacement Denso alternators. They gave a Volvo part number for a Bosch unit & also a number for a required wiring harness (cheap, I assume a short adapter of some sort). Perhaps Bosch has now created a direct replacement for the aftermarket. I don't know. I would give FCP or IPD a call & inquire. Hopefully we all learn something here.

      Edit: Even more fun if you check the Bosch Website. Try plugging in the various versions there. Here is the AL7673X they list for 2005

      I know what you're saying: volvo part# 30667103, which is the FoMoCo denso, is (most likely) superceded or at least cross referenced by volvo part# 36001463, which is a bosch. Try it and let us know if that's the case. Maybe we'll all learn something and finally the forum moderators will sticky this thread.

      Update, spoke to Jason at FCP and he concurred that the Bosch AL9436X would be correct after running my VIN through the latest version of VIDA (I have 2012). He said he could get a Denso unit too, but at $279 + $75 core. The Bosch unit is $227 + $75 core. I'm not 100% sure I want to be a guinea pig, but there are two members in this thread that reportedly have used the Bosch, albeit on 2006 cars.

      Then there's that Denso 210-0764 sitting at RockAuto (only 3 left) at $189 + $68 core.

      By the way, I called the local Denso supplier here (Bennett Auto Supply, according to the Denso website) and they cannot get either of the Denso units company-wide (they have 37 stores in FL), so the local option without having to pay shipping on a core is ruled out.

      Decisions, decisions.

      Damn alternators are getting cheap. A year ago I had to hussle a deal out of an auto parts store (price matched rock auto+AAA discount) and I still paid 250ish. Personally, I'd go with the cheaper denso via rockauto. I believe it comes with a 3 year warranty and I can confirm that they work perfectly.

      Well, I pulled the trigger and ordered the FCP Bosch alternator. The FCP unit was free shipping, plus my loyalty discount, versus RockAuto's $14 shipping but with the 5% code you can find on the internet, it boiled down to I was paying $23 more for the Bosch from FCP. I'm fine giving Scott and Nick the $23 plus I get the lifetime warranty ... and, I get to put a Bosch in a 2005, yippee! (I think). It'll be 2 or 3 weeks until I get to this, unless I have to do it sooner, thanks guys.

      Just installed the bosch unit from FCP in the v50 last week. Works great. That was the biggest PITA install of an alternator I have ever done. That TB is annoying to get on and off of the T5

      2006 or 2005 V50?

      Edit: Nevermind, I see in your profile that you have a 2006, so you would be the third person in this thread by my count that has used a Bosch in their 2006 car.

      Well, it works The Bosch AL9436X alternator went in without a hitch. Not the easiest job, but not the worst one either. Recently that award goes to the PCV job on my S60. I figure that no blood and no swearing, about 3.5 hours of time, I'm good. I encountered the usual suspects that others have mentioned and they were a little challenging (bottom passenger alternator bolt, back passenger side throttle body bolt), but fortunately I have accumulated lots of good tools over the years and am also used to dealing with tight "blind" fasteners on these cars. I hooked the car up to Vida and all the dtc's that reported numerous sensors and modules as bad were all gone. The charging voltage also went up to 14.3V, it was only 13.7V previously.

      I thought the whine I was getting would go away, but I finally realized that the noise wasn't coming from the alternator, it's coming from the electric power steering pump. I'll start a separate thread about that with a couple videos to see if you guys think the noise is normal or excessive.

      Way to go! I'm glad I have a 2.4i when I did my alternator change. Removing and replacing bolts by feel was the hardest part in my case.
      You ought to invest in a mechanic's stethoscope to pinpoint where noises are coming from. I'd misplaced mine so I used a long screw driver with the handle in my ear and the blade on the alternator case.

      Haha, my new "listening tool" is a small transmission fluid funnel with a flexible tube. The funnel part covers my ear entirely. It works really well, wonder why I never thought of it before.

      I think having a 2006 you may be in luck as there were a couple "1 year wonders" in 2004.5 & 2005. The best one to find is a Denso rebuilt (actually rebuilt by Denso).
      I am in need of a 2004.5 S40 T5 alternator don't suppose you know where I can find the part number to order? Local auto parts store gave me several to choose from but I don't know which is the right one.

      Here is the factory page. The numbers they are referring to are the last 6 of your VIN. Most likely you'll need the first one (CH -045203) possibly the second (CH 045204-250052). I added the zero's for clarity.

      I found these guys a while back and haven't done much looking at them, but it is an interestingly weird concept to have such a high power setup for such a small car. Can you imagine 320 amps?

      Why so many amps? OEM is 150 I believe, that seems plenty.

      I was able to get the number off my original alternator (Denso) and order a replacement Denso alternator from FCP Euro. The core charge is a little crazy but the final price isn't too bad if you return the old one as a core. Plus, they have a lifetime warranty on their parts.

      The Denso replacement is working great.

I called the ebay seller that I bought it from out of Chicago, they had no more in stock and wanted $180 to rebuild it. They wouldn't help me out, even considering it was giving wonky voltages after about 18 months. Oh well.

      I bought the Bosch AL9436X from FCP, https://www.fcpeuro.com/products/vol...50-c70-al9436x

      $217 with the loyalty code, plus I had to ship the core back to them for $12 (I sent them the original that I had from the first swap). Just did the install (boy I forgot how fun that was) and now I am getting a solid 14.5v and no more dimming headlights when I turn the wheel.

      The Dayco belt I bought two years ago was already cracking. Had to swap it with an overpriced Gates from Oreilly's -

      Long story short - just go FCP next time. Lifetime warranty too.

      That's unfortunate, but glad you found a good replacement at FCP Euro - they're hard to beat with the included warranty.

      FCP Euro warranty is great. They replaced my LCA's and an endlink for free.

      No, but I'm probably going to replace it anyway. Then install the other alt and see if there is too much current anywhere. In hoping that maybe it was just a faulty Bosch unit.

      Yikes, flames huh? That's an easy diagnosis (probably).
