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

"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? "

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

"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."

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.

Should have listen to another forum member when he PM this:

trader4
please add him to your ignore list for his posts, he only gets off on having stupid arguments with us on the boards.

You just been added to my ignore list.

To the original poster that started this thread, here's a post about the same problem and the solution.

http://www.xoutpost.com/934481-post52.html

Guys, let it go.
Gee, I will never post again a known quick test to confirm a component is functioning as part of a series of steps to determine fault issue, without a legal disclaimer on usage, potential issues, user stupidity challenges (do not put an electrical device in the tub when showering, etc).

Upallnight, thanks for posting a quick link to the same old problem solution of AC not working, or why does my AC stop blowing cold air in traffic, at a light, etc?

Now regarding the question of how long one can drive with this part or that part missing, broken, fallen off the car. ANSWER : Until the car dies, or causes other major system failures. All of this is dependent on the owners tolerance. See space shuttle disaster for extreme example.

As our cars age, owners move into two camps. One group will fix everything, while the other camp will decide to "drive until it dies". Newbies get to choose the camps to listen to based on economics and or skill sets. The forum is here to help those who wish to fix their cars. If you have chosen to go down the path of band aids and coat hanger repairs, remember not everyone agrees with that concept including every repair shop, as they are in the business to fix things right once.
