I apologize for that. You could have simply pointed that out a couple
posts ago, when I first replied, instead of starting personal attacks.

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?

Your statement that I responded to wasn't the above, it
was this:

"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.

areas. Overheating? Who should I believe, you or my own eyes?
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.

"Why can't you still do this with the X5? Hook up 12V to the compressor,
take the car for a drive, which provides the necessary cooling for
the condenser. If it blows cold air, the system is working. Should
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.
