I have not come across Fast-Good-Cheap before. I must look it up. But my instincts tells me good and cheap repel each other and no amount of force can bring them together and keep them together for long.

Given BMW's considerable commercial success, I have a great deal of faith in BMW's engineers or the engineers of the contractor company they use for manufacturing their parts. Therefore I am convinced those engineers would have taken the best solution at a predesigned cost level to create their FSRs. If the ebay FSR is both cheaper and superior to the BMW's FSR, I cannot imagine those engineers would missed out on that fact. So it's safe to conclude BMW would have used the ebay FSR if it was superior. The fact they didn't suggests it wasn't superior.

Let's assume for a moment the BMW engineers had no clue and did not use the best solution at a lower cost, we can look for a more competent group of engineers at other car makers. So we can see which other car manufacturer is using the ebay FSR. Is Porsche using the ebay FSR ? Is Ferrari using the ebay FSR, etc, etc. These questions should be easy to answer using google as practically nobody would treat the FSR as a trade secret. With the answers, we can decuce the following:

1. No car manufacturer uses the ebay FSR. This means the ebay FSR is crap because of all the world's engineers, not one chose to use the ebay FSR. They can't all be wrong.

2. Some respected car manufacturers use the ebay FSR. This means there is technical merit to the ebay FSR, and so it may be possibly worthwhile for people to spend their money on.

Without bothering to google, I know which outcome it will be. If you wish to confirm, please be my guest.

I am an armchair logician. I find it surprising I have greater faith in engineers making the right choices than a real engineer such as yourself.
I just glanced at the first three-four words of your long-winded post and skipped right over it. This is what everybody else is doing as well. Quit it.

As for this part, I am very interested. Does anybody know how long their FSR will last once it starts effing with your electrical system and draining the battery? Or is it just random? I have to get around to doing this. My HVAC speeds all work perfectly except the highest one which when set to high, it jumps back and forth from medium to high all by itself. But speeds 1, 2, 3, 4 all work as it should. I'm sure this will deteriorate even more soon.

I'll have you know that this is quite an old thread. I bumped it because TitanSilverE46 installed the new BPSX FSR, and he never came back to share his input on whether it was holding up or not. Of course being that it is summer time, any FSR faults are going to be a real pain in the ass if they haven't been rectified yet.

GoingNuts did share his own experience with the FSR. He located the FSR and found that there was some white buildup on the female plug connectors and the male pins of the FSR. He reported that he was able to scrape off the buildup, and that his own blower fan issues disappeared after that. This was some time ago, so I am not sure how well his fix has held up.

There are also a number of threads on Bimmerfest related to this issue that I have referenced: one is concerned with which brand of FSR to buy (most recent design with 58 pins is best... or is it?), while at least one other thread involves an autopsy of a 'failed' FSR.

For the record, my own blower fan has been chirping for the past three years. It was only yesterday that I noticed a problem. I got into the car and turned it on, but had no air coming out of the vents. This prompted me to investigate the issue. I believe the best solution is to replace both the blower fan and the FSR. I will use the BPSX FSR once it is available for purchase again.

Product Page for BPSX FSR: http://betterpartx.com/products.aspx

As a comparison, we can purchase new BEHR FSRs from PelicanParts or eEuroParts for about $65. The dealership priced me $120 for the same part. BPSX wants less than $28 for their FSR. If quality and longevity of the part are as good as what they claim, I'm sold.

My questions:
1) What is the failure mode of the FSR (FSU) ?
2) Will running a new FSR with a worn blower fan result in a quicker failure of the FSR?
3) Just how good is BPSX's 'better' FSR?

Did your blower fan emit the chirping noise associated with failing bearings? Mine has been chirping for the better part of my time spent with the car (3+ years). I had no airflow coming through the vents yesterday, which led me to this thread. I did read that a failing blower would require more current to operate, which would in turn cause failure of the FSR.
I had no problem with the blower fan itself ... no chirping so hopefully no failed bearings. The problem was the FSR which caused the fan to play funny, sometimes revving up, sometimes slowing down, finally staying on when the key was removed draining the battery. (Classic FSR fail symptom). There had been a thread suggesting this Prongless FSR offered a new approach that did not produce the heat that the OEM types had to dissipate via their prongs. Thought I would try it (3 year guarantee) and report to the forum.

As with any part ... if it is working forget it and leave it alone. My Prongless FSR is such an item, performing perfectly 4 months in. Sitting back enjoying the Bavarian motoring.

Product Recall

It seems from responses that I seem to be on only E46Fanatic that has fitted the BSPX 'Prongless' FSR to my cabin blower following the OEM failure. I have a 2001 325.
It was an awkward install, positioned where the FSR is, but quite doable. My unit has been performing perfectly for 4 months now, I have had no problems and am quite satisfied with its performance.

I was interested to see a poster say units were on back order until 5th July and I wondered why.
The reason became apparent when I received an email yesterday from the makers, APSX, that a 'revised' unit had been posted to me. I received the following 'Recall' email this morning:-
IMPORTANT RECALL NOTICE

Dear BPSX FSU Customer:

This notice is sent to you because of a product failure experienced due to a risk of part defect in our BPSX FSU product.The product was redesigned recently as version 2 to eliminate that problem completely.

What is the reason for this notice?
BPSX has decided that a defect which relates to product failure exists in parts sold between December 2010 and April 2011. Connector parts may cause the connectors melt and the blower functions to fail.

What MUST you do?
You MUST replace the part with the new part (version 2) we just mailed to you on July 5th 2011. Please use the same USPS small flat rate priority mail box, small bubble package and the return address label you will get, to send us the old part to our office at:

BPSX
9435 Waterstone Blvd. Suite 140
Cincinnati, OH 45249


Please fill out the form we sent you along with the letter with your car model/year information so that we can keep the demographics of the cars using our products.

Who to contact if you experience problems?
If you are not satisfied with the product you receive from us, you may contact:
info@apsx.com

What to do if you sold your vehicle to someone else with BPSX FSU.
If this is the case, please provide us the contact information of the new owner of your car and return the new part back to us asap. We will then update our records and send the new owner a new part.

If you have any questions about this notice please contact us at:
info@apsx.com

We apologize for any inconvenience this campaign may cause you.
Sincerely,
BPSX Better Part Solutions www.betterpartx.com

I had emailed BPSX yesterday before I received the recall notice, asking why a new unit was being posted to me. They replied as follows:-
You should have gotten the email regarding to "recall" we had to issue today.

Since two incidents we heard happened just within 30 minutes after installation, we don't expect anything wrong if you have been using it without any problem so far. But you need to replace it when you get the new unit.

As a responsible and committed company, we thought we have to inform our customers about the updates on the product.

Sorry about the any inconvenience you may have.

BPSX
When I received my original unit I noticed that a couple of the connector pins appeared to me to have a film of plastic covering them from the molding process. I carefully scrapped this off to ensure a good contact before installing. Perhaps this was the problem referred to in their recall notice and I averted it by my actions.

I am posting this as I believe members of this forum should have a balanced view on all subjects affecting them. There have been skeptics to this product such as 'GoingNuts' but we all know that many of his comments are as a result of him liking to 'stir the possum' as we say here in Oz. No matter ... Forum members have a right to hear that while I have been perfectly satisfied with this unit, there has been a recall and a revised version is now the one being sold.

I must say that I am impressed that a company has sent new units to all purchasers and is intent on having ALL the version 1 units returned from the field. Such a supplier should be supported.

I'd say nice find and progress reports. There's always a better way to engineer something, note my signature. I'd give her a go.

We'll let the purists keep their wiener roaster resistormatics. Geez, talk about resistance.... to change.

I asked of BPSX the following:-
Was it a poor connection between the loom plug and the FSR? I ask this because when I received my original unit in Dec 2010, I noticed what appeared to be a thin plastic covering on a couple of the pins due to leakage during moulding. I carefully scraped all the pins until I was satisfied that there would be good contact made.

Has anything else been changed in Version 2? I ask this because my unit is performing correctly and has done for 4 months.
BPSX replied in an email to me today:-
Yes there is a change in version 2. Version 1 did not have a part that protects from this failure completely. Because of fluctiations of the voltage coming from the blower motor (it may be due to the age of it or just the quality, but it happens), the unit may not handle it. If the blower motor produce that "unusual" voltage spike long enough, the FSU connector pins can not handle the heat and makes a white smoke and FSU fails completely.

We wanted to inform all our customers, because there were 2 incidents like that just within 30 minutes after they were installed. We sold around 100 units so far. After we discovered the reasons behind it, we replaced the units that our own BMWs use. So we strongly advise replacing the current ones. And we tried to do that through the "recall" process.

I hope that helps.

Thanks

Finally got around to swapping my original BPSX FSR for the MkII version yesterday. Only took 30mins as I had only used 1 screw to secure the FSU. easy peasy.
Had no problem with original unit after 5 months, but better safe than sorry so installed the replacement unit they sent me.

3 year warranty is great, and no extra heat from the pronged OEM type.
If interested check out BPSX website.

It held up extremely well. In fact it became a lifetime part. To prevent future build up, I used non-conductive specialist grease to fill the plug and socket. Future corrosion and build up on the connectors is no longer possible as these are now immersed in air tight seal by the grease.

Installed the BPSX unit over the weekend, worked great for about 30 minutes. Now my fan speeds are more erratic whenever it decides to even work at all. Contacted the vendor and they said that I probably didn't install the plug far enough, pretty sure I did because it was a PITA to get the prongs on the plug to where they clipped in. I'm taking it out tonight and putting the old unit back in for now.

Sorry to hear of your bad experience. Did you fit the plug to the FSR BEFORE you fitted the FSR or after. With it out it is a lot easier to ensure it is properly attached. - Had no problem with mine.

I plugged it in before installing it in location, it was a very snug fit so I don't think I could have plugged it in after it was installed.

The only other thing I can think of is there was a suggestion of a smear of plastic on a couple of the pins from the moulding process. I carefully scraped all pins before I fitted.

Other thought ... are you sure your cabin blower itself is up to scratch? Why did you change the FSR in the first place? What symptons did you have?

It was working for the most part, the gauge indicated the fan was on but on occassion it would not blow any air. It would also quit for 10 minutes or so then start up again, some times it would work for days without a problem.

It may be a problem with the blower itself but I'm not sure, I'm not getting any cricket sounds that some have described when the blower motor is going out. I hope that is not the issue, I looked at teh DIY links on that and it looks like a major PITA.

FYI the unit I replaced was a aftermarket unit, so someone has been in there before. (car only has 86K on it)

I've tried reaching Rick and no response. Blower motor in my car was on its way out for some time, so I replaced it with a new unit, and it didn't spin up. I switched back to the old FSU that I had lying around and did A/B test to confirm that the BPSX FSU was no longer working. Emailed Rick to ask for his input and how they would handle warranty claim. No response as of two weeks ago. I'm quite disappointed because I was very excited about this product and was looking forward to championing it more, with all the fuss that goes on because of FSUs.

Anyone know how I can get a hold of Rick?

Now this is interesting. As you know I have been happy with both the original unit supplied in Dec 2010 and the Mk II supplied in July 2011 which in Australia is the middle of winter. Now we are coming into warmer weather and the Mk II is starting to play up. If the car is left in the sun and heats up inside, when I return to the car and start up, the blower quickly goes to high speed for 10 - 15 secs then shuts down completely. Next morning works normally. It has now done this on several occasions but works fine on cooler days.
I emailed Rick 24/10 with my observations and while he did not reply to my email, I have received a UPS Shipping Advice 28/10 that a new unit has been posted to me.

The address I used was info@apsx.com

While I have been a strong advocate of this new technology, I think further development is needed. Perhaps the circuitry added to prevent overheating from a faulty blower motor is now causing this 'switch off' when ambient temps in the car become too high.

I'm in NA so the temperatures here have been steadily dropping for some time. Thankfully the lack of blower motor functionality hasn't been too much of a problem yet as I find that the cabin will still warm up to an acceptable level after a while. I am concerned that this will present an issue once it's cold enough for fog to start collecting on the interior of the windshield. Will try again with Rick -- hopefully your experience means that I can expect some positive response from him. If anything my failed unit could serve to help them identify issues that need to be resolved in future designs.
