- 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

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

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. |
