ebox Fan error and where located on 545i?

I'm received a Ebox fan control error (22c2F71), does anyone know what the control error means? I've checked the fuse and it's good. I also searched for the fan/ebox as I thought it was covered by the panel above the driver's feet, but only a small ecu is there and no fan or ducting to it is visible, so it looks ambient cooled. I also checked the passenger side and it's not covered by that panel.

It's located under the hood on the passenger side. You have to remove everything from the electrical box to replace the fan.

Thank you for replying, your information and the photo log really is great! I know know exactly where it is and how to dig down to it. In your case, did you also have the ebox fan control error and when you got to the fan, was it broken? Curious if it was seized or something else had happened to it.

Those pictures aren't mine, but I did change mine out 6 months ago or so. It wasn't bad--just a little "holy crap that's a lot of wires" moment when I first opened that box with all the computers in it..

To answer your question, yes I did have the error, but I do not recall what was wrong with it. I THINK the bearings were gone and it would barely turn but could not say for sure. I found a cheapo used replacement on eBay and it has worked fine ever since

Thanks! I'll do the same for the replacement, it's just a 12v fan, after all...

Don't worry, BMW can over-engineer and screw up anything

I have the same fan error when I run INPA for stored errors in memory. For me I know what caused it a couple years ago.

It was about 4 inches of water stuck right below the electronics, the fan was immersed in the stale water.

I was getting wet passenger floorboard at the time. After chasing my tail on sunroof drains, rubber trim I saw a slight bead of water under the dash as there is an air port that leads into the electronics box. Mine was not draining except into the footwell.

What has happened is the seal was bad or BMW at one time did not place the electronics cover on correctly. If you look water can shed right down the windshield and make its way under the cabin airfilter covers and the black trim that runs under the wipers.

After I cleaned dried the box I re-inserted all the electronics then ran a bead of silicone around the cover. I never had a problem since (except for the fan now being locked up)

I will eventually replace it but not urgent.

My advice run a bead of silicone sealer or silicone dielectric grease to keep any water from getting under the cover.

Thanks, mine is dry inside.

Does anyone know if the fan runs continuously, any time the car is running or is it controlled by a temp sensor. With the cover off the e-box, I can confirm the fan is not running when the engine is.

I took the e-Box fan out and the fan motor was running intermittently, I took the motor apart but the armature was worn out and not repairable. Instead of spending $145 at BMW for a complete fan unit I instead purchased a new electric motor at Radio Shack: $5.95 9-18V DC motor, PN# 2730256 it fits into it's housing as good as the original and works perfectly! The fan's impeller was easy to remove from the old motor's shaft, the new motor's shaft was exactly the same diameter.. so an easy slam dunk!

remember too, you will need to remove the wires and RF filter circuit board from the old motor and solder it to the new one, a five minute exercise. the one thing I did not duo was record which terminal on the new motor I soldered the "Red" wire of the old motor, it's important to make sure the fan is rotating in the correct direction to blow air out for the housing. If you have a 12v source, you can do a trial and error check with the fan roughly held inside the fan housing to make sure it "Blowing" before soldering anything, that is what I did.

Hey I finally purchased the DC motor from Radio Shack and installed last weekend. A perfect fit and easy to solder in the wiring and circuit.

While my Ebox was clean here is a pic of the old DC motor that had gotten wet and rusted.

It would've been nice if the motor is readily accessible to check the condition of the motor... oh well...

Yeah it's not . From the birds eye view of the ebox I couldn't tell. But I did have the Ebox fan fault in INPA, plus I knew water intrusion issue so I kind of expected to see this.

But the Radio Shack motor does the trick to a "T"
