Actually, I don't believe the French ever fielded a 7.62x51mm rifle. They went from the 7.5mm French (MAS 36, MAS 49 and MAS49/56) right to the 5.56x45 Famas.

I personally own both a MAS 36 and MAS 49/56 and yes, they had never been fired when I purchased them. Never been dropped either...never left the armory.

The brand list is growing:
Behr, GKR, Valeo, Meyle, Siemens, Hella, Uro, Denso, & Sitronic.



I hope the French aren't listening to our subtle humor ...

Definitely getting confusing....some of these look like they are just listing the "cross reference" part numbers, rather than promoting a particular brand...

While I was searching and searching and searching (I'm not French ... I don't give up that easily) ... Here are the wiring diagrams I found for the blower motor resistor. Notice in the 3 series, there are separate heater blower motor and ac blower motor final stage resistors.

(1) (2) (3) (4)

But all suffer from lack of detail.

Do you know of a better wiring diagram for the blower motor resistor operation?

Good point. How do we know which is the cross reference and which is the brand?

BTW, searching found one more brand, the amazingly cheap $40 "Power Pro" to the list (as shown below).

The previous MatWiz Behr photo was a Behr with Denso (rebranded?).

Here's a photo of Behr that's just a Behr (i.e., no Denso) for the E39 FSU (from here).

That is, I presume it's a Behr. I'm just guessing. I have 3 choices based on the label:
Behr, GKR, or BMW

How can we tell which is the manufacturer and which is the cross reference?

I bought an FSU from the BMW dealership yesterday and it looks exactly like the one Matwiz has. It is the most recent update for the FSU offered from BMW.

BMW made quite a few revisions over the years and farmed it out to different manufacturers with their specifications. The E39 is not the only model that uses this particular FSU, or similar variant, so it makes sense that BMW switched manufacturers for each revision because a large number were involved - very common in design and manufacturing.

Sitronic took over the climate control division for Bosch, so you can combine those two. http://www.sitronic.com/index.php?id=96&L=1

In most cases a car manufacturer will spec out a part and work with a component manufacturer for an integrated part in the car design. Sometimes, if production from the comp. man. is not sufficient, it will be farmed out to a second source to meet production demand. So, you will sometimes see different name brand components on the same model car in the same production month. No big deal, and nothing to worry about - similar to NGK or Bosch plugs as OE. However, if there is a design/man. flaw, then revisions are made and it might not necessarily be the original comp. man. as these type things are bid out. So, you will end up with the latest revision by a certain comp. man., in this case Sitronic/Bosch, which is the one to be looking out for. Not that the Valeo or Siemens are less quality than the Bosch, they are just not desirable because they will be of the older design or not OE. Of course, there is a possibility that BMW could have used multiple comp. man. for the latest revision right off the bat, but unlikely.

Hi Michel,

Your post helps us a lot to order the Sitronic/Bosch at the top.

Other questions arise ... like ... um ... what is "GKR" since it's on almost all of the FSR labels. And, of all the FSRs pictured, most say "BMW" in text, but only one has the BMW logo.

And, if Sitronic/Bosch is #1 for the E39, then how do we order the rest, particularly Behr and Valeo (which I had originally)?

BTW, I replaced my Valeo in March of 2008 with the $75 AutoHauz FSR. Unfortunately, I can't tell the brand from the angle of my photo in that thread (see below) of my replacement FSR, but, it doesn't look like the lower-case "s" for Sitronic/Bosch ... so I wonder what brand I have in there now ... (I sure don't want to wrestle that thing out of there again to check!)

As always, I'll stick my neck out ...

How is this for desired brand order?

#1: Sitronic/Bosch
#2: Behr
#3: Valeo,
#4: Siemens
NOT DESIRABLE: Meyle, Hella, Uro, Denso, or Power Pro

Hi,

That should be correct. As I too got my FSU from a BMW dealer (Crown BMW, btw).

Quote:
Sitronic Expands Activities SITRONIC GmbH & Co. KG, a medium-sized automotive supplier specialising in intelligent sensor and control technology based in Gärtringen, Germany, takes over the entire Air Conditioning Controls segment from Robert Bosch GmbH, effective January 01, 2009.
Good find. Good to know!

As to the dealer price going down. It was my understanding that BMW changed their pricing scheme and they are now using "dynamic" pricing that will be updated every couple of weeks, based on the Euro/Dollar exchange rate. The Euro lost a lot of its value lately, which could explain the FSU price going down here in the US.

French FSU giving up easily and riffle that never shot and dropped once. You guys are hysterical!!!

The interesting thing is that GKR is the actual manufacturer and the others are re-branding the same unit with their numbers when GKR is referenced. Same goes for the newer, revised version manufactured by Sitronic.

My old FSU actually has the GKR logo stamped into the metal, in addition to the label reference.

I just looked again at my paperweight because of this FSU off-brand failure thread.

- GKR is stamped on the metal tab of my bad (original) FSR
- The paper sticker says GKR, BMW, and Valeo

Since GKR is obviously the failed FSR, is the the trick NOT get "GKR" FSUs?

Correct. The most updated version from BMW is the one Matwiz and I have and is the one you want - Sitronic. All others are updated versions as my parts guy told me there were about three revisions to this part. They stock many of these at their dealership.

It's so nice, after six years of owning this car, to have an AC that responds to my commands without question. It's nice to get in the car, knowing that there aren't any electrical bug "surprises" waiting for me (weird light behavior, 999999 on odometer, radio going out and back on, central locking system locking and unlocking, etc...) and I can decide what temp I want it to be in the car and simply make my selection and drive.



To think, that if I had gotten off of my lazy azz and broke open my wallet when I had much more disposable income, I could have put this entire thing behind me on my way across the country from where I picked up my car to drive home. Boy, was that a HOT ride in August of 04 from Miami to Pasadena, CA.

Thanks EAC Tuning!

In another thread someone requested I post this here. I recently had my FSU break, 2 months after I replaced it (the old one lasted 9 years).


It's a Meyle, which set me back around €70.

Notice the grease above the connector. This came out of it (or so it seems). I cleaned this off and the next day it was back again.

There is no sticker on it, but on the side it says:
3148600000. Some numbers can be off, since the printing is really vague.

I've now replaced it with an old one, which will hopefully last more than 2 months.

Meyle, hmmmmm. That's one more strike against Meyle.

Here's the old list (prior to the GKR information):
#1: Sitronic/Bosch
#2: Behr
#3: Valeo,
#4: Siemens
NOT DESIRABLE: Meyle, Hella, Uro, Denso, or Power Pro

Now that we know GKR is one of the main culprits (others offer rebranded GKRs), I wonder if the list should simply be:

Recommended:
- Sitronic/Bosch

Not recommended:
- GKR
- Behr
- Valeo,
- Siemens

Certainly not recommended:
- Meyle
- Hella
- Uro
- Denso
- Power Pro

Ran into a guy in a 97 540 yesterday who had a new Meyle that he hadn't installed yet. I didn't have the heart to tell him what to expect. He was also under the assumption that he had to take apart the entire right side of his dash to get to it. I offered to replace it for him right there in the parking lot of the gas station in about 15 minutes.

It "should" take fifteen minutes but it took me an entire superbowl to get the clips to let go (they were like the alien on the face that just won't let go).

Anyway, there's a nice pictorial FSU DIY over in the E46 forums that shows a nice picture of the Hella/Behr/BMW FSU as shown below.

So far, I think we're not sure, but, Sitronic/Bosch/BMW is the only one we trust (right?).

In that same thread, you can see the "bad" FSR is branded with four names:
- GKR
- Behr
- Denso
- BMW

And, you can barely make out the GKR stamp on the screw tab.

This is yet another vote against GKR (who I presume made this bad FSU).

I just looked at my old FSU. Just like Bluebee's and mmm635's, mine is the same GKR stamped into the metal, and the paper sticker says BMW, GKR & Valeo (identical to Bluebee's picture).

Mind you, that is the FSU that was installed in 2003 by the dealer, to replaced the original bad one. My fan was stuck on full volume. It lasted about 4-5 years, and I replaced it with the current Sitronic/BMW in 2009.

So the GKR worked 4-5 years. We still need to see how long the Sitronic will last. But so far, it looks that it is better than most out there, as per Bluebee list.

I agree that the Sitronic/Bosch seems like the best bet for our E39s at this point.

BTW, while researching dead-battery threads for a newbie, I noticed that the GKR isn't always molded into the aluminum ears; in the case of Kraft's original (failed) final stage resistor, the GKR is apparently molded in the inside of the final stage unit harness connector.

Any one tried the Blower Final Stage Resistor sold in eBay

Any one has any luck with the Final Stage Register sold in eBay?

One has a 12-month warranty:

http://cgi.ebay.com/ebaymotors/ws/eB...category=46094

There is one made by Eurasia. It is posted at:

http://cgi.ebay.com/ebaymotors/BMW-E...Q5fAccessories

I bought no brand one from eBay (from New York) and it went bad in less than
6 months. I am looking for another replacement.

Thanks,

JP
