Let us know how your recall update (Powertrain Shutdown / Loss of Power) went

[JD4S]

Here's a weird one: after taking delivery of my 4S about three weeks ago, I read (on this forum!) about the software recall.

Went to the manufacturer website, put in my VIN: "no recall necessary". Phew! No problem!

Then 3 days ago, an urgent email from Porsche Mothership: MANDATORY RECALL. MUST BOOK SERVICE APPOINTMENT!

Dang. So I booked the appointment.

Today, the service manager called me and said "Hey -- no problem, sir! I pulled up your car on the computer and your vehicle is NOT affected!"

I'm relieved, I guess? Kind of a case of right hand / left hand not checking their voicemails. Maybe?

Exact same thing happened to me. Had latest update 4 weeks ago, everything working great. Got recall email, also checked on recall site and confirmed it was showing there as well, set appointment, got call back 30 minutes later saying MY20 not on list anymore. My dealership said that they have done 3 recall updates within an hour and no reported issues. Keeping my appointment for August just in case something changes. Also said they can’t keep loaner cars as they are selling everything they have. Did offer to have someone drive me on any errands during the install.

Just got back from the dealer after completing my recall update. Took almost exactly 1.5 hours, no issues thus far. Everything is exactly the same including all of my personal settings, favorites, etc.

All good so far.

No problem with the update.
Service tech said they he knew of a couple they did so far and no issues.

No problems. Took the dealer an hour or so. Driven it a couple times today since and no noticeable changes or problems.

Update went smoothly, however within just a few miles of driving (on the same day of receiving the car back from Porsche) I lost power on a dual carriage way. Scary.

Now what?

Uh.... take it back to the dealer.

I really hope this is just a case of the dealer not applying the update or not applying it correctly.
The last thing we need is a f'ed up recall.

I took the car back to the dealer (luckily this happened just 5 minutes away from them so I took it straight there), they confirmed the update had been applied correctly.

They are hoping there’s some deeper issue with my vehicle that they might be able to identify tomorrow. I hope so too because, as you say, none of us want an f’ed up recall.

Funnily enough, aside from an all wheel drive error after a launch control once, I hadn’t seen this power loss error many others had been getting prior to the update that was supposed to fix it. ?

It is hard to imagine how the dealer can mess up this update. They connect PIWIS and select the AutoProgramming function. They don't manually pick versions or anything like that. At the end they manually verify the version of DME and PE are 0014 and 0012 respectively just to confirm that the auto-update succeeded.
Also according to the AMB5 TSB, if they perform an autoprogramming routine in any of the three modles (DME, front PE, rear PE) it will automatically program all three modules so there should be no chance to leave one of them in the wrong version.

This is not like the WMA5/6 update that needs a lot of manual interventions and it has a sequence of update procedures.

A few options I can think of that happened here:

1. The update was not applied correctly, despite them saying so
2. The update does not fully fix the issue, only partially
3. Your error was caused by a different issue than the one that was patched
4. The patch itself caused a different regression which now introduces a new way to have sudden loss of power

None of which are good.

Thanks for the info - please keep us posted on what they say. I’m scheduled next week for my update.

so it didn't go smoothly, the update was ineffective.
I hope that this doesn't devolve into issues that keep the car off the road for a long time.

5. The update doesn't fix the issue at all.

a question regarding your region.
do you think that I'd be able to get from the norfolk Va area to the ferry at lewes DE on 1 charge? there seems to be very little DC charging on that route? or should I go around via new castle DE to my final stop in Cape May NJ?
