It was obvious to me that the dealer only used the outer bleed valves when they did it.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I bought my car last November as a CPO car with 18,000 miles. I was told that the brake fluid was flushed as part of the certification.
This morning I decided to flush out the system with some ATE blue. It was obvious to me that the dealer only used the outer bleed valves when they did it.
The inner valves clearly had never had the rubber cover removed since leaving Germany.
What is wrong with the world when even a Porsche service center can't (or won't) do a simple procedure correctly.
I could possibly understand an indy service place not knowing that there were two bleed valves per caliper but Porsche?!!!!
I know some of the mechanics at the local dealer and I have never asked if they bleed both nipples. We have debated this issue at our local work on cars days when we bleed brakes. Some say it is necessary only to bleed the outside nipple as any fluid/air in the 2 inside pistons would be forced into the 2 outside pistons and then out of the outside bleed nipple. There is a tube that connects the outside and inside of the caliper together. We also debate which nipple you bleed first, the inside or outside.
One of these days I will ask.
I'm less than thrilled with my Porsche dealer as well, but then again, the Lexus dealer is no better. But they're all in it as a business for profit so like anything else it pays to shop around. For example, my dealer wanted $498.00 for the short shifter yet another Porsche dealer about 50 miles from here sold it to me for $340.00. Yes, they were both sold as OEM and not as B&M.
My car is also CPO but I am not really sold on the integrity of the CPO certification process. But there is a great deal of peace of mind knowing I have a factory warranty.
May be a dumb question (won't be my first), but I'm having my brake system bled in the next few weeks before bedding the car for the winter. Holbert's in Warrington PA is going to do it (along with an oil service). With this post in mind, are there any specific instructions I should give their service folks or should they know exactly what needs to be done for this routine maintenance?
Here is an excerpt from the Renntech DYI section.
"Bleed order - Right rear, Left rear, Right front, Left front.
Place your drain tube over the outside bleed nipple and in the bottle (remember it will need to hold a liter when you are done).
Bleed the outer bleeder valve first
. Open each bleeder valve until clear, bubble free brake fluid emerges.
Take care to bleed at each brake caliper and at both bleeder valves.
Carefully tighten the bleed screw. Wipe off the area and replace the rubber protective cap over the bleed screw.
Repeat steps 8-10 for the interior bleed screw
. Then reinstall the wheel and move on to the next wheel."
Yeah, just spoke with Bill in Service this AM. I've had work done there before, and have been very satisfied. They're thorough, careful, and don't overprice their services (relative of course with any Porsche). He agreed that oil and brake flush need to be done, but felt that cooling system can be simply checked and not flushed.
