As to posting pictures, the fan is in the car, I'm not going to tear it
out just to post pics. And pics aren't likely to do much to solve
the question of what exactly failed.

"So when you decided to get rid of the X and sell it to a new X owner are you going to replace the DISA valve and Aux Fan? Probably not and probably won't tell the new owner about these two problems. "

And there you go again, with more totally unsupported personal attacks.
Is that what this forum is about now? As to lacking power in the
mid-range, you're once again in over your head. I've seen absolutely
no noticeable difference in performance with the DISA working or
disabled. I have seen others here report the same thing. Are you
going to personally attack them too?

"In the good old days you would just jump 12V to the compressor to confirm its ability to function. Now days all parts up stream must be working before system tests will complete."

So, stop lying.

I think you started the personal attack when you called me a liar.

Wrote row--and away he goes. Upallnight, might as well as go for the throat or assume others will ignore his ranting posts and let him have the last useless word. He continually demonstrates courtesy, reason, wisdom and respect doesn't alway prevail.

I also updated the electric fan thread. I think he will have difficulty waging war on two fronts and finding anything to support his argument, using an attic fan as a comparison, that an electric fan won't work in place of the clutch fan.

On topic--The auxiliary fan has other purposes. One being to prevent overheating and should be replaced ASAP. Some problems, or lack there of, owners are having are climate sensitive. New Jersey is cold country so the auxiliary fan is less critical than an area that is consistently hot in the summer. The following video explains the DISA valve functions: https://www.youtube.com/watch?v=B_HWy9gOymE One thing not mentioned, at some point the pin that goes though the flap can fall out and get sucked into the engine resulting in valve or cylinder damage.

To those that are irritated that this is off topic--please try to look at it as entertainment or a version of the infamous Saturday night skit--Jane you ignorant slut.

I have a simple answer to this issue. Why not take to vehicle to the dealer
or a reputable indy and get the system in question tested. Then decide what the
next course of action should be. If you don't have to money to fix it, save up then
get it done in the future. Either way arguing with others doesn't solve the problem
but getting it fixed will.

Never said that your experience is not factual. Only said it is anecdotal and cannot be universally accepted.

Pile on--there's that--I'm the victim complex.

You've seen other posts verifying your experience---in my view, because of the importance of a properly working aux fan, they should have also replaced the fan ASAP.

Why should I replace a $450 fan so it can fail again-- I have over 114,000 miles on the original aux fan that has been activated far more than yours ever will be.

Less critical is still critical.

The point of posting the video link was to show that performance is effected with an explanation of how the DISA works. Along with lost performance is reduced mileage. Here is another source of verification: BMW E60 5-Series DISA Valve Replacement (M54 6 Cylinder) - Pelican Parts Technical Article

My posts aren't to convince you of anything---that would follow the definition of insanity. My posts are for those that might take you seriously.

Case in point--a 10hp attic fan of any size to endorse your point is at best funny. If you had done a little research you would find years and years of the proven benefits of an electric fan over a clutch fan.

I did't say you can't loosen the clutch fan nut with a wrench, a screwdriver and a hammer. I said some do and for some it does not work. Plus, I don't use that method because there is a risk of damaging the water pump. I also provided a link to a $10 best practice tool set. Based on the cost of a water verses a $10 tool to eliminate that risk I think it is extremely poor advice to recommend otherwise.

My electric puller fan did not blow up. The fan is fine. The controller fried. I replaced it with the same one. I had recently adjusted the controller to the summer setting. I'm guessing that had something to do with it. Bragging--if that was the case, I wouldn't have posted the controller failure. And I never even implied clutch fans are inferior as far as quality. My electric fan cools better than my clutch fan did and does not use horsepower to turn it. Based on my particular application it has benefits that I deem important.

I've driven the X5 here in the environment I use it in and I've
never had the temp gauge go above normal. NEVER. I've seen
other folks report the same thing.

"New Jersey is cold country so the auxiliary fan is less critical than an area that is consistently hot in the summer. "

Wow, you figured that out? I suppose I should replace that $450
fan so it can fail again just in case the car somehow winds up in
Phoenix just to make you and upallnight happy.

Watched your video link. It's pretty much OK, except he claims
that the DISA improves low and high end performance. I recall
Bentley saying it increased mid-range performance. He's wrong
about the gasket not being replaceable separately. I have one
on the car, they are available from a variety of sources.

Since you want to drag your electric fan conversion into it,
I never said it would not work in place of the mechanical fan.
I said that I think your claim of it being a miracle 5 or 10hp
boost in available power is nuts and I showed you what a
10hp fan actually looks like. It wasn't a typical attic fan,
it was a whopping huge one like 5 ft in diameter.
You may think I'm an idiot, but at least I can easily get the
X5 fan off with a good old 1 1/4" wrench, how about that
for mechanical skills?

I see your less than a year old electric fan conversion recently
blew up, so IDK why about this you're bragging. My stock, original mechanical fan is still running fine.

work, no?"

You replied:

"Another shade tree mechanic fix. Fix it right or don't fix it at all. From you previous posts I see that you are taking my advice about not fixing stuffs that breaks on your X."

My post said nothing about what the final solution is. It was not
a "fix", it was a test suggestion. In fact, I only made the post to
clarify StephenVa's post that said you can't do this test with an X5
like you could in other cars. And to that you started the attack by
calling me a "shade tree mechanic" and making snide remarks.
And you are lying when you imply that I ever suggested anything
like that as a "fix".

It's a curious thing. I get jumped on by you. Yet in
another recent thread, there were a couple of buffoons claiming
that it was peachy keen to go ahead and change an alternator
without first disconnecting the battery. He even had a picture
of the energized alternator cable suspended right in the work
area.l Now *that* is something worthy of correcting, worthy of
warning, interjecting. Yet, guys like you were silent on that.
But I'm the shade tree mechanic. Go figure.

Since you know how to quote people, why don't you quote me in the above referenced thread, instead of just typing something together and claim that I made a post on the thread.

The posts I quoted are right here, in this thread.

#23 Where I said:

#24, Where you started the attack. You quoted my post above,
and said:

Just you, in your own words. And it's an obvious attack based on
a lie, because hooking 12V up was for a *test*. StephenVA claimed
that you can't do that test with the X5, like you could with older
cars. I thought it should be clarified, so I replied. Neither
Stephen or I ever suggested in any way that it was a *fix*.

Feel free to apologize at any time.

I can find my posts, not the post that you said I jumped all over you about some alternator. PS until your last post no where in your previous postings did you ever mention that hooking up 12 volts was for a test. My two posts stated that this should only be used as a test.

You should not drive with the car set up like this since the system is designed to cycle off and on. With 12 volts jumped to the compressor, you eliminate the cycling of the system off and on. If he has a bad aux fan the high side pressure will build to the point that you can blow out the condensor coil or a refrigerant hose. The high side sensor prevent this from occurring, but it won't do this if you have the system jumped.

Another shade tree mechanic fix. Fix it right or don't fix it at all. From you previous posts I see that you are taking my advice about not fixing stuffs that breaks on your X.

Nope, my statement and explanation implies that this should only be done only as a test. It should not be considered a FIX or a work around to get back AC in the car without fixing the real problem.

Let See my statement was Fix it right or don't fix it.
You have a broken DISA valve that you know of, but didn't fix but still drive the X.
You have a broken Aux Fan that you know of, but didn't fix but still drive the X.

Glad I'm no longer in the market for a X. With owners that maintain cars like you I can see why there are so many noobs coming on this forum after purchasing a use X.

The video claims DISA is there for performance at the low and high end.
Bentley says it's to improve mid-range performance. All I can tell
you is that I couldn't see any *noticeable* difference in performance
with the DISA operational or not. I've seen others here post the same
thing. Your mileage claim is a new one and IDK what you're basing
that on. I did not see any difference in mileage. And I don't see
the harm in others hearing that. IMO, the DISA is like an appendix,
a wee little refinement that gives some minimal benefit that typical
drivers will never see. They will however see all the repair bills
associated with the added complexity. Others here have reported
exactly the same thing, why don't you start correcting them?

The 10hp fan is indeed pretty funny. It takes a whopping big fan moving
a whole lot of air to consume 10hp. It's the power of a lawn tractor.
If you want to believe that little mechanical X5 fan is using all that
power, be my guest. It would for sure make BMW pretty stupid.
I mean they are doing anything and everything, desperate to get
even a tiny boost in MPG for decades, yet they used a mechanical
fan that sucks up 10hp, about 20% of what the vehicle uses on
the highway. Go figure.

Removing the fan, you do it your way, I'll do it mine. You think a
water pump is fragile and it's going to be easily damaged. Can you
point us to one person here who damaged the WP removing the fan?
Lots of people are just using the 1 1/4" wrench and hammer, where
are all the failures? Others can judge for themselves. And I've said
many times, your car, your dollars, your choice.

Electric fan didn't blow up, just the controller, not much difference
IMO. It didn't last a year, my mechanical fan is original. And it's
news to me that the stock cooling system in the BMW is inadequate.
Maybe you should take that up with and explain it to BMW. They
are supposed to build the ultimate driving machine, yet they
produced millions of vehicles with inadequate engine cooling so
that you need to remove the stock fan?

I've been giving you some slack since english is obviously your second language.

To your posts, yes, you should add a disclaimer--- Please note that my comments should not be taken seriously.

I can't see lost performance said the closed mind blind man.
It doesn't matter what source for verification we use. Don't use what I referenced. Use the Bentley manual stating there is lost performance which you claim is not the case. You are not agreeing with your own source of reference and have no awareness that is the case.

You don't know why I mentioned reduced mileage but then you say if an electric fan freed up any horsepower BMW would be using them to increase mileage. Doesn't seem you understand yourself. Have you noticed in many newer vehicles including BMWs the mechanical fan has been eliminated?

Never said, even implied, the cooling system is inadequate. I said in my application the electric puller fan has benefits I deem important.

Your opinion the controller is the same as a fan failure is ludicrous. The controller I am using could be an ongoing failure but there are many other controllers out there or I can eliminate the controller as the thermostat. The overall electric fan benefits are exceeding my expectations. The controller failure is a small bump in the road.

I'm not going to address your attic fan or a lawn tractor blade bs. If readers know the earth isn't flat they know that means nothing more than you know attic fans and lawn tractors exist.

I agree that there are those that hit the wrench with a hammer--have at it. My point is there is no logic to take the risk of damaging the water pump. I stand corrected the Bentley manual, states to put an inch and a quarter wrench on the nut and whack the hell out of it with a big hammer. I also spoke with several of the current ebay sources that sell the tool for $10-20. You are again correct, they keep offering it even though they've collectively only sold 7 in last 10+ years they have been making them.
