1) the DISA on my X5 is a factory OEM BMW valve, not an aftermarket copy, and
2) the steel pin is still in place, and hasn't fallen into the intake manifold.

Why haven't I checked it yet?

1) I've got one car down (for 9 months, so far) for repairs (waiting for my back to let me crawl under it, again),
2) had to make minor repairs on another, prior to inspection this week,
3) had to assist my wife with projects that had to be done ASAP (she's trying to compensate for the passing of her father, recently), and
4) preparing, in secret, my repairs for the X5 (not permitted to find/fix the P0171, P0174, P0313 codes until the first car is done).

She left for the weekend to babysit dogs for a highschool chum (actually gets money to do so), so I am completing my home-made smoke device, to find the vacuum leaks

1) sauerkraut jar,
2) two tire valves,
3) siphon pump,
4) tiki-torch wick,
5) silicone tubing,
6) mineral oil, and
7) a soldering iron

Attachment 81322

It makes smoke, but kind of wispy, so I probably need to add glycerine for thicker smoke. A larger jar and a better heat source would be of benefit, too, but this was all I had on hand.

I'll be pulling off the DISA tomorrow, to see if it's genuine. If not, I'll have to buy a used BMW DISA on E-bay (in secret); I'd never willingly install a DISA without the GAS kit, after reading of the pin falling out.

I finally pulled the Disa valve, without smoke-testing it first, since my smoke machine is still under construction (sealing two leaks with epoxy). It's been almost a month since I parked the X5 with three recurring codes
https://xoutpost.com/bmw-sav-forums/...-codes-me.html

I just pulled the DISA as the sun was setting, and plugged the hole with a towel, having wasted the day fixing the garage side-door (to be able to use it again, after sealing it shut 15 years back; new threshold, locks). I was surprised how easily it came out, practically zero resistance while pulling. I would say that surely the flattened O-ring was leaking, but I haven't finished my smoke machine to verify that.https://xoutpost.com/bmw-sav-forums/...s-codes-4.html

I was glad to see that the steel pin was intact, that the valve still worked when tested, and that the BMW logo and part number were on the housing, so I can install the GAS repair kit (and not worry about the DISA again). I'll fix the DISA and re-install it tomorrow!

P.S. I decided to overhaul the DISA after I posted earlier. It took me just short of two hours, since I had to find tools in my home computer/activity room (sorta mixed-up between projects) without going out to the X5, or my truck, where most of my proper tools are). Getting the old O-ring out and the groove cleaned-up took the longest time; I made some micro-grooves in the slot, but I used a lot of Superlube grease to try to compensate.

New driving lights (nice color)
New lower water pump hose.

Looking at the wds, it sure looks like with s536 aux water pump is only wired to webasto. Gotta look more in to it, since wds doesn't tell pin number or wire color behind ac panel.

The water pump is controlled by Webasto but it works as auxiliary water pump if IHKA is activated and there is temp demand (pump controlled by K-bus command from IHKA even if Webasto itself is not started). If you check the live status on Webasto with for example INPA you should see this.

Wds shows that without webasto pump is controlled from pin 9 blue 26pin connector from ihka. With webasto, wire goes only from webasto to the pump...

Or does it needed to be coded as aux heater to this work? (But even that really doesn't resolve what i'm after)

But even when I set ihka temp to 32c, pump isn't running, until I start webasto.

I already forgot you are talking about 3.0i, not the typical 3.0d with mandatory Webasto. If there is a separate voltage supply wire from Webasto to aux water pump (this can be clearly seen on Webasto wiring Pin 1), it must be controlled by Webasto and bus signal from IHKA. If the voltage comes directly from IHKA then it must be coded as active on IHKA.

Yea, just was thinking this. So I will try to code aux water pump not enabled from ihka.

Changing the alternator bracket gasket, and it’s a mofo’ing beach!! Not fun!

Isn't it wonderful?

I think I could do it again much quicker, but that first time was a pain. And it doesn't help that everything is covered in oil/dirt while you're working down there.
