Where is this screw/hole you speak of to pop off airbag? Behind the wheel? Underneath the bottom front of the airbag? Woops. Never mind. Found it, and airbag is off.

Now, I can unplug the airbag wire connector plug, but the black wire harness disappears off to the right behind the plate that is held on by the 4 green torx screws. How do you disconnect that wire so the airbag and wire can be completely removed from the steering wheel?

If you got Alan Gun (AGLA) to thicken it, are you happy with it?

So, is the bleeding procedure incompletely done if the ABS pump is not bled? Does the car have to go to the dealer anyway, to hook it to the PIWIS for ABS bleed? If the ABS has to be bled, any way to do it without the dealer or a PIWIS?

Most dealers do not both to bleed the ABS unless the system has been open (i.e. lines or components replaced).

I have a PST (and PIWIS) and and I usually do not bleed the ABS on my own car.

Thanks.

I'd like to be your next door neighbor! (Can I borrow a cup of sugar, and the PIWIS?)

Does Porsche not have a "bleed valve" at the ABS manifold/pumpmotor assembly? Both of my Lexus vehicles, '92 LS and '01 RX, do. Actually the '92 has two additional ones, one at the ABS pump/manifold and another at the Trac pump/manifold/accumulater.

Absent that extra bleed valve you'll need to get the Porsche's ABS/PSM/Trac pumpmotor to activate for an extended period of time to get the "old" brake fluid to flow out of "those" brake line sections. My '92 even has a 3000 PSI nitrogen filled accumulator that holds a substantial level of brake fluid that must also be "bled".

Even with the extra fittings, valve(s), the Lexus "techie" who did my '92 put it on a rack and "drove" the rear wheels for a minute or so to get the Trac system to activate and force fluid flow in from/into those line sections.

Porsche's method to bleed the ABS is to hookup a PST2 or PIWIS tester and use a built-in function that starts the ABS pump during bleeding.
